The War Powers Resolution: Concepts and Practice

Summary: This report discusses and assesses the War Powers Resolution and its application since enactment in 1973, providing detailed background on various cases in which it was used, as well as cases in which issues of its applicability were raised.

Summary: In the post-Cold War world, Presidents have continued to commit U.S. Armed Forces into potential hostilities, sometimes without a specific authorization from Congress. Thus the War Powers Resolution and its purposes continue to be a potential subject of controversy. On June 7, 1995, the House defeated, by a vote of 217-201, an amendment to repeal the central features of the War Powers Resolution that have been deemed unconstitutional by every President since the law's enactment in 1973. In 1999, after the President committed U.S. military forces to action in Yugoslavia without congressional authorization, Representative Tom Campbell used expedited procedures under the Resolution to force a debate and votes on U.S. military action in Yugoslavia, and later sought, unsuccessfully, through a federal court suit to enforce presidential compliance with the terms of the War Powers Resolution.

Summary: The War Powers Resolution (P.L. 93-148) was enacted over the veto of President Nixon on November 7, 1973, to provide procedures for Congress and the President to participate in decisions to send U.S. Armed Forces into hostilities. Section 4(a)(1) requires the President to report to Congress any introduction of U.S. forces into hostilities or imminent hostilities. When such a report is submitted, or is required to be submitted, Section 5(b) requires that the use of forces must be terminated within 60 to 90 days unless Congress authorizes such use or extends the time period. Section 3 requires that the "President in every possible instance shall consult with Congress before introducing" U.S. Armed Forces into hostilities or imminent hostilities.

Summary: From 1975 through March 2017, Presidents have submitted 168 reports as the result of the War Powers Resolution, but only one, the 1975 Mayaguez seizure, cited Section 4(a)(1), which triggers the 60-day withdrawal requirement, and in this case the military action was completed and U.S. Armed Forces had disengaged from the area of conflict when the report was made. The reports submitted by the President since enactment of the War Powers Resolution cover a range of military activities, from embassy evacuations to full-scale combat military operations, such as the Persian Gulf conflict, and the 2003 war with Iraq, the intervention in Kosovo, and the anti-terrorism actions in Afghanistan. In some instances, U.S. Armed Forces have been used in hostile situations without formal reports to Congress under the War Powers Resolution. On one occasion, Congress exercised its authority to determine that the requirements of Section 4(a)(1) became operative on August 29, 1983, through passage of the Multinational Force in Lebanon Resolution (P.L. 98-119). In 1991 and 2002, Congress authorized, by law, the use of military force against Iraq. In several instances none of the President, Congress, or the courts has been willing to initiate the procedures of or enforce the directives in the War Powers Resolution.

Summary: In the 115th Congress, U.S. military operations related to the joint counter-Houthi campaign conducted by the Kingdom of Saudi Arabia and the United Arab Emirates (UAE) in Yemen spurred congressional legislative action in both houses of Congress. The Senate on December 13, 2018, voted to adopt S.J.Res. 54, a joint resolution to "direct the removal of United States Armed Forces from hostilities in the Republic of Yemen that have not been authorized by Congress," marking the first instance that such a joint resolution received consideration and passed the full Senate under the expedited consideration provisions of Section 1013 of the Department of State Authorization Act, Fiscal Years 1984 and 1985 (P.L. 98-164; 50 U.S.C. §1546a). In the 116th Congress, the House of Representatives on February 13, 2019, voted to adopt a similar joint resolution on U.S. military involvement in Yemen, H.J.Res. 37, and the Senate is expected to take up a companion measure, S.J.Res. 7, in March 2019.

Under the Constitution, the war powers are divided between Congress and the President. Among other relevant grants, Congress has the power to declare war and raise and support the armed forces (Article I, Section 8), while the President is Commander in Chief (Article II, Section 2). It is generally agreed that the Commander-in-Chief role gives the President power to utilize the armed forces to repel attacks against the United States, but there has long been controversy over whether he is constitutionally authorized to send forces into hostile situations abroad without a declaration of war or other congressional authorization.

Congressional concern about presidential use of armed forces without congressional authorization intensified after the Korean conflict. During the Vietnam War, Congress searched for a way to assert authority to decide when the United States should become involved in a war or the armed forces be utilized in circumstances that might lead to hostilities. On November 7, 1973, it passed the War Powers Resolution ( P.L. 93-148 ) over the veto of President Nixon. The main purpose of the Resolution was to establish procedures for both branches to share in decisions that might get the United States involved in war. The drafters sought to circumscribe the President's authority to use armed forces abroad in hostilities or potential hostilities without a declaration of war or other congressional authorization, yet provide enough flexibility to permit him to respond to attack or other emergencies.

The record of the War Powers Resolution since its enactment has been mixed, and after 40 years it remains controversial. Some Members of Congress believe the Resolution has on some occasions served as a restraint on the use of armed forces by Presidents, provided a mode of communication, and given Congress a vehicle for asserting its war powers. Others have sought to amend the Resolution because they believe it has failed to assure a congressional voice in committing U.S. troops to potential conflicts abroad. Others in Congress, along with executive branch officials, contend that the President needs more flexibility in the conduct of foreign policy and that the time limitation in the War Powers Resolution is unconstitutional and impractical. Some have argued for its repeal.

This report examines the provisions of the War Powers Resolution, actual experience in its use from its enactment in 1973 through March 2015, and proposed amendments to it. Appendix A lists instances which Presidents have reported to Congress under the War Powers Resolution, and Appendix B lists certain instances of the use of U.S. Armed Forces that were not reported.

Provisions of the War Powers Resolution(P.L. 93-148)

Section 1 establishes the title, "The War Powers Resolution." The law is frequently referred to as the "War Powers Act," the title of the measure passed by the Senate. Although the latter is not technically correct, it does serve to emphasize that the War Powers Resolution, embodied in a joint resolution which complies with constitutional requirements for lawmaking, is a law.

Section 2 states the Resolution's purpose and policy, with Section 2(a) citing as the primary purpose to "insure that the collective judgment of both the Congress and the President will apply to the introduction of United States Armed Forces into hostilities, or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, and to the continued use of such forces in hostilities or in such situations."

Section 2(b) points to the Necessary and Proper Clause of the Constitution as the basis for legislation on the war powers. It provides that "Under Article I, section 8, of the Constitution it is specifically provided that Congress shall have the power to make all laws necessary and proper for carrying into execution, not only its own powers but also all other powers vested by the Constitution in the Government of the United States...."

Section 2(c) states the policy that the powers of the President as Commander in Chief to introduce U.S. Armed Forces into situations of hostilities or imminent hostilities "are exercised only pursuant to—

(2) specific statutory authorization, or

(3) a national emergency created by attack upon the United States, its territories or possessions, or its armed forces."

Section 3 of the War Powers Resolution requires the President "in every possible instance" to consult with Congress before introducing U.S. Armed Forces into situations of hostilities and imminent hostilities, and to continue consultations as long as the armed forces remain in such situations. The House report elaborated:

A considerable amount of attention was given to the definition of consultation . Rejected was the notion that consultation should be synonymous with merely being informed. Rather, consultation in this provision means that a decision is pending on a problem and that Members of Congress are being asked by the President for their advice and opinions and, in appropriate circumstances, their approval of action contemplated. Furthermore, for consultation to be meaningful, the President himself must participate and all information relevant to the situation must be made available.

The House version specifically called for consultation between the President and the leadership and appropriate committees. This was changed to less specific wording in conference, however, in order to provide more flexibility.

Section 4 requires the President to report to Congress whenever he introduces U.S. Armed Forces abroad in certain situations. Of key importance is Section 4(a)(1) because it triggers the time limit in Section 5(b). Section 4(a)(1) requires reporting within 48 hours, in the absence of a declaration of war or congressional authorization, the introduction of U.S. Armed Forces "into hostilities or into situations where imminent involvement in hostilities is clearly indicated by the circumstances."

Some indication of the meaning of hostilities and imminent hostilities is given in the House report on its War Powers bill:

The word hostilities was substituted for the phrase armed conflict during the subcommittee drafting process because it was considered to be somewhat broader in scope. In addition to a situation in which fighting actually has begun, hostilities also encompasses a state of confrontation in which no shots have been fired but where there is a clear and present danger of armed conflict. " Imminent hostilities" denotes a situation in which there is a clear potential either for such a state of confrontation or for actual armed conflict.

Section 4(a)(2) requires the reporting of the introduction of troops "into the territory, airspace or waters of a foreign nation, while equipped for combat, except for deployments which relate solely to supply, replacement, repair, or training of such forces." According to the House report this was to cover

the initial commitment of troops in situations in which there is no actual fighting but some risk, however small, of the forces being involved in hostilities. A report would be required any time combat military forces were sent to another nation to alter or preserve the existing political status quo or to make the U.S. presence felt. Thus, for example, the dispatch of Marines to Thailand in 1962 and the quarantine of Cuba in the same year would have required Presidential reports. Reports would not be required for routine port supply calls, emergency aid measures, normal training exercises, and other noncombat military activities.

Section 4(a)(3) requires the reporting of the introduction of troops "in numbers which substantially enlarge United States Armed Forces equipped for combat already located in a foreign nation." The House report elaborated:

While the word "substantially" designates a flexible criterion, it is possible to arrive at a common-sense understanding of the numbers involved. A 100% increase in numbers of Marine guards at an embassy—say from 5 to 10—clearly would not be an occasion for a report. A thousand additional men sent to Europe under present circumstances does not significantly enlarge the total U.S. troop strength of about 300,000 already there. However, the dispatch of 1,000 men to Guantanamo Bay, Cuba, which now has a complement of 4,000 would mean an increase of 25%, which is substantial. Under this circumstance, President Kennedy would have been required to report to Congress in 1962 when he raised the number of U.S. military advisers in Vietnam from 700 to 16,000.

All of the reports under Section 4(a), which are to be submitted to the Speaker of the House and the President pro tempore of the Senate, are to set forth

(A) the circumstances necessitating the introduction of United States Armed Forces;

(B) the constitutional and legislative authority under which such introduction took place; and

(C) the estimated scope and duration of the hostilities or involvement.

Section 4(b) requires the President to furnish such other information as Congress may request to fulfill its responsibilities relating to committing the nation to war.

Section 4(c) requires the President to report to Congress periodically, and at least every six months, whenever U.S. forces are introduced into hostilities or any other situation in Section 4(a).

The objectives of these provisions, the conference report stated, was to "ensure that the Congress by right and as a matter of law will be provided with all the information it requires to carry out its constitutional responsibilities with respect to committing the Nation to war and to the use of United States Armed Forces abroad."

Section 5(a) deals with congressional procedures for receipt of a report under Section 4(a)(1). It provides that if a report is transmitted during a congressional adjournment, the Speaker of the House and the President pro tempore of the Senate, when they deem it advisable or if petitioned by at least 30% of the Members of their respective Houses, shall jointly request the President to convene Congress in order to consider the report and take appropriate action.

Section 5(b) was intended to provide teeth for the War Powers Resolution. After a report "is submitted or is required to be submitted pursuant to section 4(a)(1), whichever is earlier," Section 5(b) requires the President to terminate the use of U.S. Armed Forces after 60 days unless Congress (1) has declared war or authorized the action; (2) has extended the period by law; or (3) is physically unable to meet as a result of an armed attack on the United States. The 60 days can be extended for 30 days by the President if he certifies that "unavoidable military necessity respecting the safety of United States Armed Forces" requires their continued use in the course of bringing about their removal.

Section 5(c) requires the President to remove the forces at any time if Congress so directs by concurrent resolution; the effectiveness of this subsection is uncertain because of the 1983 Supreme Court decision on the legislative veto. It is discussed in Part II of this report.

Section 6 establishes expedited procedures for congressional consideration of a joint resolution or bill introduced to authorize the use of armed forces under Section 5(b). They provide for

(a) a referral to the House Foreign Affairs [International Relations] or Senate Foreign Relations Committee, the committee to report one measure not later than 24 calendar days before the expiration of the 60 day period, unless the relevant House determines otherwise by a vote;

(b) the reported measure to become the pending business of the relevant House and be voted on within three calendar days, unless that House determines otherwise by vote; in the Senate the debate is to be equally divided between proponents and opponents;

(c) a measure passed by one House to be referred to the relevant committee of the other House and reported out not later than 14 calendar days before the expiration of the 60 day period, the reported bill to become the pending business of that House and be voted on within 3 calendar days unless determined otherwise by a vote;

(d) conferees to file a report not later than four calendar days before the expiration of the 60 day period. If they cannot agree within 48 hours, the conferees are to report back in disagreement, and such report is to be acted on by both Houses not later than the expiration of the 60-day period.

Section 7 establishes similar priority procedures for a concurrent resolution to withdraw forces under Section 5(c). For a recent use of these procedures see the section on the " Legislative Veto ," below.

Section 8 sets forth certain interpretations relating to the Resolution. Section 8(a) states that authority to introduce armed forces is not to be inferred from any provision of law or treaty unless such law, or legislation implementing such treaty, specifically authorizes the introduction of armed forces into hostilities or potential hostilities and states that it is "intended to constitute specific statutory authorization within the meaning of this joint resolution." This language was derived from a Senate measure and was intended to prevent a security treaty or military appropriations act from being used to authorize the introduction of troops. It was also aimed against using a broad resolution like the Tonkin Gulf Resolution to justify hostilities abroad. This resolution had stated that the United States was prepared to take all necessary steps, including use of armed force, to assist certain nations, and it was cited by Presidents and many Members as congressional authorization for the Vietnam war.

Section 8(b) states that further specific statutory authorization is not required

to permit members of United States Armed Forces to participate jointly with members of the armed forces of one or more foreign countries in the headquarters operations of high-level military commands which were established prior to the date of enactment of this joint resolution and pursuant to the United Nations Charter or any treaty ratified by the United States prior to such date.

This section was added by the Senate to make clear that the resolution did not prevent U.S. forces from participating in certain joint military exercises with allied or friendly organizations or countries. The conference report stated that the "high-level" military commands meant the North Atlantic Treaty Organization, (NATO), the North American Air Defense Command (NORAD) and the United Nations command in Korea.

Section 8(c) defines the introduction of armed forces to include the assignment of armed forces to accompany regular or irregular military forces of other countries when engaged, or potentially engaged, in hostilities. The conference report on the War Powers Resolution explained that this was language modified from a Senate provision requiring specific statutory authorization for assigning members of the Armed Forces for such purposes. The report of the Senate Foreign Relations Committee on its bill said

The purpose of this provision is to prevent secret, unauthorized military support activities and to prevent a repetition of many of the most controversial and regrettable actions in Indochina. The ever deepening ground combat involvement of the United States in South Vietnam began with the assignment of U.S. "advisers" to accompany South Vietnamese units on combat patrols; and in Laos, secretly and without congressional authorization, U.S. "advisers" were deeply engaged in the war in northern Laos.

Section 8(d) states that nothing in the Resolution is intended to alter the constitutional authority of either the Congress or the President. It also specifies that nothing is to be construed as granting any authority to introduce troops that would not exist in the absence of the Resolution. The House report said that this provision was to help insure the constitutionality of the Resolution by making it clear that nothing in it could be interpreted as changing the powers delegated by the Constitution.

Section 9 is a separability clause, stating that if any provision or its application is found invalid, the remainder of the Resolution is not to be affected.

From its inception, the War Powers Resolution was controversial because it operated on the national war powers, powers divided by the Constitution in no definitive fashion between the President and Congress. Congress adopted the resolution in response to the perception that Presidents had assumed more authority to send forces into hostilities than the framers of the Constitution had intended for the Commander in Chief. President Nixon in his veto message challenged the constitutionality of the essence of the War Powers Resolution, and particularly two provisions. He argued that the legislative veto provision, permitting Congress to direct the withdrawal of troops by concurrent resolution, was unconstitutional. He also argued that the provision requiring withdrawal of troops after 60-90 days unless Congress passed legislation authorizing such use was unconstitutional because it checked presidential powers without affirmative congressional action. Every President since the enactment of the War Powers Resolution has taken the position that it is an unconstitutional infringement on the President's authority as Commander in Chief.

War Powers of the President and Congress

The heart of the challenge to the constitutionality of the War Powers Resolution rests on differing interpretations by the two branches of the respective war powers of the President and Congress. These differing interpretations, especially the assertions of presidential authority to send forces into hostile situations without a declaration of war or other authorization by Congress, were the reason for the enactment of the Resolution.

The congressional view was that the framers of the Constitution gave Congress the power to declare war, meaning the ultimate decision whether or not to enter a war. Most Members of Congress agreed that the President as Commander in Chief had power to lead the U.S. forces once the decision to wage war had been made, to defend the nation against attack, and perhaps in some instances to take other action such as rescuing American citizens. But, in this view, he did not have the power to commit armed forces to war. By the early 1970s, the congressional majority view was that the constitutional balance of war powers had swung too far toward the President and needed to be corrected. Opponents argued that Congress always held the power to forbid or terminate U.S. military action by statute or refusal of appropriations, and that without the clear will to act the War Powers Resolution would be ineffective.

In his veto message, President Nixon said the Resolution would impose restrictions upon the authority of the President which would be dangerous to the safety of the Nation and "attempt to take away, by a mere legislative act, authorities which the President has properly exercised under the Constitution for almost 200 years."

The War Powers Resolution in Section 2(c) recognized the constitutional powers of the President as Commander in Chief to introduce forces into hostilities or imminent hostilities as "exercised only pursuant to (1) a declaration of war, (2) specific statutory authorization, or (3) a national emergency created by attack upon the United States, its territories or possessions, or its armed forces." The executive branch has contended that the President has much broader authority to use forces, including for such purposes as to rescue American citizens abroad, rescue foreign nationals where such action facilitates the rescue of U.S. citizens, protect U.S. Embassies and legations, suppress civil insurrection, implement the terms of an armistice or cease-fire involving the United States, and carry out the terms of security commitments contained in treaties.

On June 23, 1983, the Supreme Court in INS v. Chadha , ruled unconstitutional the legislative veto provision in Section 244(c)(2) of the Immigration and Nationality Act. Although the case involved the use of a one-House legislative veto, the decision cast doubt on the validity of any legislative veto device that was not presented to the President for signature. The Court held that to accomplish what the House attempted to do in the Chadha case "requires action in conformity with the express procedures of the Constitution's prescription for legislative action: passage by a majority of both Houses and presentment to the President." On July 6, 1983, the Supreme Court affirmed a lower court's decision striking down a provision in another law that permitted Congress to disapprove by concurrent (two-House) resolution.

Since Section 5(c) requires forces to be removed by the President if Congress so directs by a concurrent resolution, it is constitutionally suspect under the reasoning applied by the Court. A concurrent resolution is adopted by both chambers, but it does not require presentment to the President for signature or veto. Some legal analysts contend, nevertheless, that the War Powers Resolution is in a unique category which differs from statutes containing a legislative veto over delegated authorities. Perhaps more important, some observers contend, if a majority of both Houses ever voted to withdraw U.S. forces, the President would be unlikely to continue the action for long, and Congress could withhold appropriations to finance further action. Because the War Powers Resolution contains a separability clause in Section 9, most analysts take the view that the remainder of the joint resolution would not be affected even if Section 5(c) were found unconstitutional.

Congress has taken action to fill the gap left by the possible invalidity of the concurrent resolution mechanism for the withdrawal of troops. On October 20, 1983, the Senate voted to amend the War Powers Resolution by substituting a joint resolution, which requires presentment to the President, for the concurrent resolution in Section 5(c), and providing that it would be handled under the expedited procedures in Section 7. The House and Senate conferees agreed not to amend the War Powers Resolution itself, but to adopt a free standing measure relating to the withdrawal of troops. The measure, which became law, provided that any joint resolution or bill to require the removal of U.S. Armed Forces engaged in hostilities outside the United States without a declaration of war or specific statutory authorization would be considered in accordance with the expedited procedures of Section 601(b) of the International Security and Arms Export Control Act of 1976, except that it would be amendable and debate on a veto limited to 20 hours. The priority procedures embraced by this provision applied in the Senate only. Handling of such a joint resolution by the House was left to that Chamber's discretion.

House Members attempted to use Section 5(c) to obtain a withdrawal of forces from Somalia. On October 22, 1993, Representative Benjamin Gilman introduced H.Con.Res. 170 , pursuant to Section 5(c) of the War Powers Resolution, directing the President to remove U.S. Armed Forces from Somalia by January 31, 1994. Using the expedited procedures called for in Section 5(c), the Foreign Affairs Committee amended the date of withdrawal to March 31, 1994, (the date the President had already agreed to withdraw the forces), and the House adopted H.Con.Res. 170 . The Foreign Affairs Committee reported:

Despite such genuine constitutionality questions, the committee acted in accordance with the expedited procedures in section 7. The committee action was premised on a determination that neither individual Members of Congress nor Committees of Congress should make unilateral judgments about the constitutionality of provisions of law.

Despite the use of the phrase "directs the President," the sponsor of the resolution and Speaker of the House Thomas Foley expressed the view that because of the Chadha decision, the resolution would be nonbinding. The March 31, 1994, withdrawal date was later enacted as Section 8151 of P.L. 103-139 , signed November 11, 1993.

The automatic withdrawal provision has become perhaps the most controversial provision of the War Powers Resolution. Section 5(b) requires the President to withdraw U.S. forces from hostilities within 60-90 days after a report is submitted or required to be submitted under Section 4(a)(1). The triggering of the time limit has been a major factor in the reluctance of Presidents to report, or Congress to insist upon a report, under Section 4(a)(1).

Drafters of the War Powers Resolution included a time limit to provide some teeth for Congress, in the event a President assumed a power to act from provisions of resolutions, treaties, or the Constitution which did not constitute an explicit authorization. The Senate report called the time limit "the heart and core" of the bill that "represents, in an historic sense, a restoration of the constitutional balance which has been distorted by practice in our history and, climatically, in recent decades." The House report emphasized that the Resolution did not grant the President any new authority or any freedom of action during the time limits that he did not already have.

Administration officials have objected that the provision would require the withdrawal of U.S. forces simply because of congressional inaction during an arbitrary period. Since the resolution recognizes that the President has independent authority to use armed forces in certain circumstances, they state, "on what basis can Congress seek to terminate such independent authority by the mere passage of time?" In addition, they argue, the imposition of a deadline interferes with successful action, signals a divided nation and lack of resolve, gives the enemy a basis for hoping that the President will be forced by domestic opponents to stop an action, and increases risk to U.S. forces in the field. This issue has not been dealt with by the courts.

Major Cases and Issues Prior to the Persian Gulf War

Perceptions of the War Powers Resolution tended to be set during the Cold War. During the 1970s the issues revolved largely around the adequacy of consultation. The 1980s raised more serious issues of presidential compliance and congressional willingness to use the War Powers Resolution to restrain presidential action. With regard to Lebanon in 1983, Congress itself invoked the War Powers Resolution, but in the 1987-1988 Persian Gulf tanker war Congress chose not to do so. Following is a summary of major U.S. military actions and the issues they raised relating to the War Powers Resolution from its enactment in 1973 to August 1990.

Vietnam Evacuations and Mayaguez: What Is Consultation?

As the Vietnam War ended, on three occasions, in April 1975, President Ford used U.S. forces to help evacuate American citizens and foreign nationals. In addition, in May 1975 President Ford ordered the retaking of a U.S. merchant vessel, the SS Mayaguez which had been seized by Cambodian naval patrol vessels. All four actions were reported to Congress citing the War Powers Resolution. The report on the Mayaguez recapture was the only War Powers report to date to specifically cite Section 4(a)(1), but the question of the time limit was moot because the action was over by the time the report was filed.

Among the problems revealed by these first four cases were differences of opinion between the two branches on the meaning of consultation. The Ford Administration held that it had met the consultation requirement because the President had directed that congressional leaders be notified prior to the actual commencement of the introduction of armed forces. The prevailing congressional view was that consultation meant that the President seek congressional opinion, and take it into account, prior to making a decision to commit armed forces.

Iran Hostage Rescue Attempt: Is Consultation Always Necessary and Possible?

After an unsuccessful attempt on April 24, 1980, to rescue American hostages being held in Iran, President Carter submitted a report to Congress to meet the requirements of the War Powers Resolution, but he did not consult in advance. The Administration took the position that consultation was not required because the mission was a rescue attempt, not an act of force or aggression against Iran. In addition, the Administration contended that consultation was not possible or required because the mission depended upon total surprise.

Some Members of Congress complained about the lack of consultation, especially because legislative-executive meetings had been going on since the Iranian crisis had begun the previous year. Just before the rescue attempt, the Senate Foreign Relations Committee had sent a letter to Secretary of State Cyrus Vance requesting formal consultations under the War Powers Resolution. Moreover, shortly before the rescue attempt, the President outlined plans for a rescue attempt to Senate Majority Leader Robert Byrd but did not say it had begun. Senate Foreign Relations Committee Chairman Frank Church stressed as guidelines for the future: (1) consultation required giving Congress an opportunity to participate in the decisionmaking process, not just informing Congress that an operation was underway; and (2) the judgment could not be made unilaterally but should be made by the President and Congress.

El Salvador: When Are Military Advisers in Imminent Hostilities?

One of the first cases to generate substantial controversy because it was never reported under the War Powers Resolution was the dispatch of U.S. military advisers to El Salvador. At the end of February 1981, the Department of State announced the dispatch of 20 additional military advisers to El Salvador to aid its government against guerilla warfare. There were already 19 military advisers in El Salvador sent by the Carter Administration. The Reagan Administration said the insurgents were organized and armed by Soviet bloc countries, particularly Cuba. By March 14, the Administration had authorized a total of 54 advisers, including experts in combat training.

The President did not report the situation under the War Powers Resolution. A State Department memorandum said a report was not required because the U.S. personnel were not being introduced into hostilities or situations of imminent hostilities. The memorandum asserted that if a change in circumstances occurred that raised the prospect of imminent hostilities, the Resolution would be complied with. A justification for not reporting under Section 4(a)(2) was that the military personnel being introduced were not equipped for combat. They would, it was maintained, carry only personal side arms which they were authorized to use only in their own defense or the defense of other Americans.

The State Department held that Section 8(c) of the War Powers Resolution was not intended to require a report when U.S. military personnel might be involved in training foreign military personnel, if there were no imminent involvement of U.S. personnel in hostilities. In the case of El Salvador, the memorandum said, U.S. military personnel "will not act as combat advisors, and will not accompany Salvadoran forces in combat, on operational patrols, or in any other situation where combat is likely."

On May 1, 1981, 11 Members of Congress challenged the President's action by filing suit on grounds that he had violated the Constitution and the War Powers Resolution by sending the advisers to El Salvador. Eventually there were 29 co-plaintiffs, but by June 18, 1981, an equal number of Members (13 Senators and 16 Representatives) filed a motion to intervene in the suit, contending that a number of legislative measures were then pending before Congress and that Congress had ample opportunity to vote to end military assistance to El Salvador if it wished.

On October 4, 1982, U.S. District Court Judge Joyce Hens Green dismissed the suit. She ruled that Congress, not the court, must resolve the question of whether the U.S. forces in El Salvador were involved in a hostile or potentially hostile situation. While there might be situations in which a court could conclude that U.S. forces were involved in hostilities, she ruled, the "subtleties of fact-finding in this situation should be left to the political branches." She noted that Congress had taken no action to show it believed the President's decision was subject to the War Powers Resolution. On November 18, 1983, a federal circuit court affirmed the dismissal and on June 8, 1984, the Supreme Court declined consideration of an appeal of that decision.

As the involvement continued and casualties occurred among the U.S. military advisers, various legislative proposals relating to the War Powers Resolution and El Salvador were introduced. Some proposals required a specific authorization prior to the introduction of U.S. forces into hostilities or combat in El Salvador. Other proposals declared that the commitment of U.S. Armed Forces in El Salvador necessitated compliance with Section 4(a) of the War Powers Resolution, requiring the President to submit a report.

Neither approach was adopted in legislation, but the Senate Foreign Relations Committee reported that the President had "a clear obligation under the War Powers Resolution to consult with Congress prior to any future decision to commit combat forces to El Salvador." On July 26, 1983, the House rejected an amendment to the Defense Authorization bill ( H.R. 2969 ) to limit the number of active duty military advisers in El Salvador to 55, unless the President reported any increase above that level under Section 4(a)(1) of the War Powers Resolution. Nevertheless, the Administration in practice kept the number of trainers at 55.

Honduras: When Are Military Exercises More than Training?

Military exercises in Honduras in 1983 and subsequent years raised the question of when military exercises should be reported under the War Powers Resolution. Section 4(a)(2) requires the reporting of introduction of troops equipped for combat, but exempts deployments which relate solely to training.

On July 27, 1983, President Reagan announced "joint training exercises" planned for Central America and the Caribbean. The first contingent of U.S. troops landed in Honduras on August 8, 1983, and the series of ground and ocean exercises continued for several years, involving thousands of ground troops plus warships and fighter planes.

The President did not report the exercises under the War Powers Resolution. He characterized the maneuvers as routine and said the United States had been regularly conducting joint exercises with Latin American countries since 1965. Some Members of Congress, on the other hand, contended that the exercises were part of a policy to support the rebels or "contras" fighting the Sandinista Government of Nicaragua, threatening that government, and increased the possibility of U.S. military involvement in hostilities in Central America.

Several Members of Congress called for reporting the actions under the War Powers Resolution, but some sought other vehicles for congressional control. In 1982, the Boland amendment to the Defense Appropriations Act had already prohibited use of funds to overthrow the Government of Nicaragua or provoke a military exchange between Nicaragua or Honduras. Variations of this amendment followed in subsequent years. After press reports in 1985 that the option of invading Nicaragua was being discussed, the Defense Authorization Act for Fiscal Year 1986 stated the sense of Congress that U.S. Armed Forces should not be introduced into or over Nicaragua for combat. In 1986, after U.S. helicopters ferried Honduran troops to the Nicaraguan border area, Congress prohibited U.S. personnel from participating in assistance within land areas of Honduras and Costa Rica within 120 miles of the Nicaraguan border, or from entering Nicaragua to provide military advice or support to paramilitary groups operating in that country. Gradually the issue died with peace agreements in the region and the electoral defeat of the Sandinista regime in Nicaragua in 1990.

Lebanon: How Can Congress Invoke the War Powers Resolution?

The War Powers Resolution faced a major test when Marines sent to participate in a Multinational Force in Lebanon in 1982 became the targets of hostile fire in August 1983. During this period President Reagan filed three reports under the War Powers Resolution, but he did not report under Section 4(a)(1) that the forces were being introduced into hostilities or imminent hostilities, thus triggering the 60-90 day time limit.

On September 29, 1983, Congress passed the Multinational Force in Lebanon Resolution determining that the requirements of Section 4(a)(1) of the War Powers Resolution became operative on August 29, 1983. In the same resolution, Congress authorized the continued participation of the Marines in the Multinational Force for 18 months. The resolution was a compromise between Congress and the President. Congress obtained the President's signature on legislation invoking the War Powers Resolution for the first time, but the price for this concession was a congressional authorization for the U.S. troops to remain in Lebanon for 18 months.

The events began on July 6, 1982, when President Reagan announced he would send a small contingent of U.S. troops to a multinational force for temporary peacekeeping in Lebanon. Chairman of the House Foreign Affairs Committee Clement Zablocki wrote President Reagan that if such a force were sent, the United States would be introducing forces into imminent hostilities and a report under Section 4(a)(1) would be required. When the forces began to land on August 25, President Reagan reported but did not cite Section 4(a)(1) and said the agreement with Lebanon ruled out any combat responsibilities. After overseeing the departure of the Palestine Liberation Organization force, the Marines in the first Multinational Force left Lebanon on September 10, 1982.

The second dispatch of Marines to Lebanon began on September 20, 1982. President Reagan announced that the United States, France, and Italy had agreed to form a new multinational force to return to Lebanon for a limited period of time to help maintain order until the lawful authorities in Lebanon could discharge those duties. The action followed three events that took place after the withdrawal of the first group of Marines: the assassination of Lebanon President-elect Bashir Gemayel, the entry of Israeli forces into West Beirut, and the massacre of Palestinian civilians by Lebanese Christian militiamen.

On September 29, 1982, President Reagan submitted a report that 1,200 Marines had begun to arrive in Beirut, but again he did not cite Section 4(a)(1), saying instead that the American force would not engage in combat. As a result of incidents in which Marines were killed or wounded, there was again controversy in Congress on whether the President's report should have been filed under Section 4(a)(1). In mid-1983 Congress passed the Lebanon Emergency Assistance Act of 1983 requiring statutory authorization for any substantial expansion in the number or role of U.S. Armed Forces in Lebanon. It also included Section 4(b) that stated:

Nothing in this section is intended to modify, limit, or suspend any of the standards and procedures prescribed by the War Powers Resolution of 1983.

President Reagan reported on the Lebanon situation for the third time on August 30, 1983, still not citing Section 4(a)(1), after fighting broke out between various factions in Lebanon and two Marines were killed.

The level of fighting heightened, and as the Marine casualties increased and the action enlarged, there were more calls in Congress for invocation of the War Powers Resolution. Several Members of Congress said the situation had changed since the President's first report and introduced legislation that took various approaches. Senator Charles Mathias introduced S.J.Res. 159 stating that the time limit specified in the War Powers Resolution had begun on August 31, 1983, and authorizing the forces to remain in Lebanon for a period of 120 days after the expiration of the 60-day period. Representative Thomas Downey introduced H.J.Res. 348 directing the President to report under Section 4(a)(1) of the War Powers Resolution. Senator Robert Byrd introduced S.J.Res. 163 finding that Section 4(a)(1) of the war powers resolution applied to the present circumstances in Lebanon. The House Appropriations Committee approved an amendment to the continuing resolution for FY1984 ( H.J.Res. 367 ), sponsored by Representative Clarence Long, providing that after 60 days, funds could not be "obligated or expended for peacekeeping activities in Lebanon by United States Armed Forces," unless the President had submitted a report under Section 4(a)(1) of the War Powers Resolution. A similar amendment was later rejected by the full body, but it reminded the Administration of possible congressional actions.

On September 20, congressional leaders and President Reagan agreed on a compromise resolution invoking Section 4(a)(1) and authorizing the Marines to remain for 18 months. The resolution became the first legislation to be handled under the expedited procedures of the War Powers Resolution. On September 28, the House passed H.J.Res. 364 by a vote of 270 to 161. After 3 days of debate, on September 29, the Senate passed S.J.Res. 159 by a vote of 54 to 46. The House accepted the Senate bill by a vote of 253 to 156. As passed, the resolution contained four occurrences that would terminate the authorization before 18 months: (1) the withdrawal of all foreign forces from Lebanon, unless the President certified continued U.S. participation was required to accomplish specified purposes; (2) the assumption by the United Nations or the Government of Lebanon of the responsibilities of the Multinational Force; (3) the implementation of other effective security arrangements; or (4) the withdrawal of all other countries from participation in the Multinational Force.

Shortly afterward, on October 23, 1983, 241 U.S. Marines in Lebanon were killed by a suicide truck bombing, bringing new questions in Congress and U.S. public opinion about U.S. participation. On February 7, 1984, President Reagan announced the Marines would be redeployed and on March 30, 1984, reported to Congress that U.S. participation in the Multinational Force in Lebanon had ended.

Grenada: Do the Expedited Procedures Work?

On October 25, 1983, President Reagan reported to Congress "consistent with" the War Powers Resolution that he had ordered a landing of approximately 1,900 U.S. Army and Marine Corps personnel in Grenada. He said that the action was in response to a request from the Organization of Eastern Caribbean States which had formed a collective security force to restore order in Grenada, where anarchic conditions had developed, and to protect the lives of U.S. citizens.

Many Members of Congress contended that the President should have cited Section 4(a)(1) of the War Powers Resolution, which would have triggered the 60-90 day time limitation. On November 1, 1983, the House supported this interpretation when it adopted, by a vote of 403-23, H.J.Res. 402 declaring that the requirements of Section 4(a)(1) had become operative on October 25. The Senate did not act on this measure and a conference was not held. The Senate had adopted a similar measure on October 28 by a vote of 64 to 20, but on November 17 the provision was deleted in the conference report on the debt limit bill to which it was attached. Thus both Houses had voted to invoke Section 4(a)(1), but the legislation was not completed.

On November 17, White House spokesman Larry Speakes said the Administration had indicated that there was no need for action as the combat troops would be out within the 60-90 day time period. Speaker Thomas O'Neill took the position that, whether or not Congress passed specific legislation, the War Powers Resolution had become operative on October 25. By December 15, 1983, all U.S. combat troops had been removed from Grenada.

Eleven Members of Congress filed a suit challenging the constitutionality of President Reagan's invasion of Grenada. A district judge held that courts should not decide such cases unless the entire Congress used the institutional remedies available to it. An appellate court subsequently held that the issue was moot because the invasion had been ended.

Libya: Should Congress Help Decide on Raids to Undertake in Response to International Terrorism?

The use of U.S. forces against Libya in 1986 focused attention on the application of the War Powers Resolution to use of military force against international terrorism.

Tensions between the United States and Libya under the leadership of Col. Muammar Qadhafi had been mounting for several years, particularly after terrorist incidents at the Rome and Vienna airports on December 27, 1985. On January 7, 1986, President Reagan said that the Rome and Vienna incidents were the latest in a series of brutal terrorist acts committed with Qadhafi's backing that constituted armed aggression against the United States.

The War Powers issue was first raised on March 24, 1986, when Libyan forces fired missiles at U.S. aircraft operating in the Gulf of Sidra. In response, the United States fired missiles at Libyan vessels and at Sirte, the Libyan missile site involved. The U.S. presence in the Gulf of Sidra, an area claimed by Libya, was justified as an exercise to maintain freedom of the seas, but it was widely considered a response to terrorist activities.

Subsequently, on April 5, 1986, a terrorist bombing of a discotheque in West Berlin occurred and an American soldier was killed. On April 14 President Reagan announced there was irrefutable evidence that Libya had been responsible, and U.S. Air Force planes had conducted bombing strikes on headquarters, terrorist facilities, and military installations in Libya in response.

The President reported both cases to Congress although the report on the bombing did not cite Section 4(a)(1) and the Gulf of Sidra report did not mention the War Powers Resolution at all. Since the actions were short lived, there was no issue of force withdrawal, but several Members introduced bills to amend the War Powers Resolution. One bill called for improving consultation by establishing a special consultative group in Congress. Others called for strengthening the President's hand in combating terrorism by authorizing the President, notwithstanding any other provision of law, to use all measures he deems necessary to protect U.S. persons against terrorist threats.

Persian Gulf, 1987: When Are Hostilities Imminent?

The War Powers Resolution became an issue in activities in the Persian Gulf after an Iraqi aircraft fired a missile on the USS Stark on May 17, 1987, killing 37 U.S. sailors. The attack broached the question of whether the Iran-Iraq war had made the Persian Gulf an area of hostilities or imminent hostilities for U.S. forces. Shortly afterwards, the U.S. adoption of a policy of reflagging and providing a naval escort of Kuwaiti oil tankers through the Persian Gulf raised full force the question of whether U.S. policy was risking involvement in war without congressional authorization. During 1987 U.S. Naval forces operating in the Gulf increased to 11 major warships, 6 minesweepers, and over a dozen small patrol boats, and a battleship-led formation was sent to the Northern Arabian Sea and Indian Ocean to augment an aircraft carrier battle group already there.

For several months the President did not report any of the deployments or military incidents under the War Powers Resolution, although on May 20, 1987, after the Stark incident, Secretary of State Shultz submitted a report similar to previous ones consistent with War Powers provisions, but not mentioning the Resolution. No reports were submitted after the USS Bridgeton struck a mine on July 24, 1987, or the U.S.-chartered Texaco-Caribbean struck a mine on August 10 and a U.S. F-14 fighter plane fired two missiles at an Iranian aircraft perceived as threatening.

Later, however, after various military incidents on September 23, 1987, and growing congressional concern, the President began submitting reports "consistent with" the War Powers Resolution and on July 13, 1988, submitted the sixth report relating to the Persian Gulf. None of the reports were submitted under Section 4(a)(1) or acknowledged that U.S. forces had been introduced into hostilities or imminent hostilities. The Reagan administration contended that the military incidents in the Persian Gulf, or isolated incidents involving defensive reactions, did not add up to hostilities or imminent hostilities as envisaged in the War Powers Resolution. It held that "imminent danger" pay which was announced for military personnel in the Persian Gulf on August 27, 1987, did not trigger Section 4(a)(1). Standards for danger pay, namely, "subject to the threat of physical harm or danger on the basis of civil insurrection, civil war, terrorism, or wartime conditions," were broader than for hostilities of the War Powers Resolution, and had been drafted to be available in situations to which the War Powers Resolution did not apply.

Some Members of Congress contended that if the President did not report under Section 4(a)(1), Congress itself should declare such a report should have been submitted, as it had in the Multinational Force in Lebanon Resolution. Several resolutions to this effect were introduced, some authorizing the forces to remain, but none were passed. The decisive votes on the subject took place in the Senate. On September 18, 1987, the Senate voted 50-41 to table an amendment to the Defense authorization bill ( S. 1174 ) to apply the provisions of the War Powers Resolution. The Senate also sustained points of order against consideration of S.J.Res. 217 , which would have invoked the War Powers Resolution, on December 4, 1987, and a similar bill the following year, S.J.Res. 305 , on June 6, 1988.

The Senate approach was to use legislation to assure a congressional role in the Persian Gulf policy without invoking the War Powers Resolution. Early in the situation, both Chambers passed measures requiring the Secretary of Defense to submit a report to Congress prior to the implementation of any agreement between the United States and Kuwait for U.S. military protection of Kuwaiti shipping, and such a report was submitted June 15, 1987. Later, the Senate passed a measure that called for a comprehensive report by the President within 30 days and provided expedited procedures for a joint resolution on the subject after an additional 30 days. The House did not take action on the bill.

As in the case of El Salvador, some Members took the War Powers issue to court. On August 7, 1987, Representative Lowry and 110 other Members of Congress filed suit in the U.S. District Court for the District of Columbia, asking the court to declare that a report was required under Section 4(a)(1). On December 18, 1987, the court dismissed the suit, holding it was a nonjusticiable political question, and that the plaintiffs' dispute was "primarily with fellow legislators."

Compliance with the consultation requirement was also an issue. The Administration developed its plan for reflagging and offered it to Kuwait on March 7, 1987, prior to discussing the plan with Members of Congress. A June 15, 1987, report to Congress by the Secretary of Defense stated on the reflagging policy, "As soon as Kuwait indicated its acceptance of our offer, we began consultations with Congress which are still ongoing." This was too late for congressional views to be weighed in on the initial decision, after which it became more difficult to alter the policy. Subsequently, however, considerable consultation developed and the President met with various congressional leaders prior to some actions such as the retaliatory actions in April 1988 against an Iranian oil platform involved in mine-laying.

With recurring military incidents, some Members of Congress took the position that the War Powers Resolution was not being complied with, unless the President reported under Section 4(a)(1) or Congress itself voted to invoke the Resolution. Other Members contended the Resolution was working by serving as a restraint on the President, who was now submitting reports and consulting with Congress. Still other Members suggested the Persian Gulf situation was demonstrating the need to amend the War Powers Resolution.

As a result of the Persian Gulf situation, in the summer of 1988 both the House Foreign Affairs Committee and the Senate Foreign Relations Committee, which established a Special Subcommittee on War Powers, undertook extensive assessments of the War Powers Resolution. Interest in the issue waned after a cease-fire between Iran and Iraq began on August 20, 1988, and the United States reduced its forces in the Persian Gulf area.

Invasion of Panama: Why Was the War Powers Issue Not Raised?

On December 20, 1989, President George H.W. Bush ordered 14,000 U.S. military forces to Panama for combat, in addition to 13,000 already present. On December 21, he reported to Congress under the War Powers Resolution but without citing Section 4(a)(1). His stated objectives were to protect the 35,000 American citizens in Panama, restore the democratic process, preserve the integrity of the Panama Canal treaties, and apprehend General Manuel Noriega, who had been accused of massive electoral fraud in the Panamanian elections and indicted on drug trafficking charges by two U.S. federal courts. The operation proceeded swiftly and General Noriega surrendered to U.S. military authorities on January 3. President Bush said the objectives had been met, and U.S. forces were gradually withdrawn. By February 13, all combat forces deployed for the invasion had been withdrawn, leaving the strength just under the 13,597 forces stationed in Panama prior to the invasion.

The President did not consult with congressional leaders before his decision, although he did notify them a few hours in advance of the invasion. Some Members of Congress had been discussing the problem of General Noriega for some time. Before Congress adjourned, it had called for the President to intensify unilateral, bilateral, and multilateral measures and consult with other nations on ways to coordinate efforts to remove General Noriega from power. The Senate had adopted an amendment supporting the President's use of appropriate diplomatic, economic, and military options "to restore constitutional government to Panama and to remove General Noriega from his illegal control of the Republic of Panama," but had defeated an amendment authorizing the President to use U.S. military force to secure the removal of General Noriega "notwithstanding any other provision of law."

The Panama action did not raise much discussion in Congress about the War Powers Resolution. This was in part because Congress was out of session. The first session of the 101 st Congress had ended on November 22, 1989, and the second session did not begin until January 23, 1990, when the operation was essentially over and it appeared likely the additional combat forces would be out of Panama within 60 days of their deployment. The President's action in Panama was popular in American public opinion and supported by most Members of Congress because of the actions of General Noriega. After it was over, on February 7, 1990, the House Passed H.Con.Res. 262 which stated that the President had acted "decisively and appropriately in ordering United States forces to intervene in Panama."

Major Cases and Issues in the Post-Cold War World

After the end of the Cold War in 1990, the United States began to move away from unilateral military actions toward actions authorized or supported by the United Nations (U.N.). Under the auspices of U.N. Security Council resolutions, U.S. forces were deployed in Kuwait and Iraq, Somalia, former Yugoslavia/Bosnia/Kosovo, and Haiti. This raised the new issue of whether the War Powers Resolution applied to U.S. participation in U.N. military actions. It was not a problem during the Cold War because the agreement among the five permanent members required for Security Council actions seldom existed. An exception, the Korean War, occurred before the War Powers Resolution was enacted.

The more basic issue—under what circumstances congressional authorization is required for U.S. participation in U.N. military operations—is an unfinished debate remaining from 1945. Whether congressional authorization is required depends on the types of U.N. action and is governed by the U.N. Participation Act (P.L. 79-264, as amended), as well as by the War Powers Resolution and war powers under the Constitution. Appropriations action by Congress also may be determinative as a practical matter.

For armed actions under Articles 42 and 43 of the United Nations Charter, Section 6 of the U.N. Participation Act authorizes the President to negotiate special agreements with the Security Council " which shall be subject to the approval of the Congress by appropriate Act or joint resolution ," providing for the numbers and types of armed forces and facilities to be made available to the Security Council. Once the agreements have been concluded, further congressional authorization is not necessary, but no such agreements have been concluded.

Section 7 of the United Nations Participation Act, added in 1949 by P.L. 81-341, authorizes the detail of up to 1,000 personnel to serve in any noncombatant capacity for certain U.N. peaceful settlement activities. The United States has provided personnel to several U.N. peacekeeping missions, such as observers to the U.N. Truce Supervision Organization in Palestine since 1948, that appear to fall within the authorization in Section 7 of the Participation Act. Controversy has arisen when larger numbers of forces have been deployed or when it appears the forces might be serving as combatants.

The War Powers Resolution neither excludes United Nations actions from its provisions nor makes any special procedures for them. Section 8(a)(2) states that authority to introduce U. S. Armed Forces into hostilities shall not be inferred from any treaty unless it is implemented by legislation specifically authorizing the introduction and stating that it is intended to constitute specific statutory authorization within the meaning of the War Powers resolution. One purpose of this provision was to ensure that both Houses of Congress be affirmatively involved in any U.S. decision to engage in hostilities pursuant to a treaty, since only the Senate approved a treaty.

From 1990 through 1999, Congress primarily dealt with the issue on a case-by-case basis, but Members also enacted some measures seeking more control over U.S. participation in future peacekeeping actions wherever they might occur. The Defense Appropriations Act for FY1994 stated the sense of Congress that funds should not be expended for U.S. Armed Forces serving under U.N. Security Council actions unless the President consults with Congress at least 15 days prior to deployment and not later than 48 hours after such deployment, except for humanitarian operations. The Defense Authorization Act for FY1994 required a report to Congress by April 1, 1994, including discussion of the requirement of congressional approval for participation of U.S. Armed Forces in multinational peacekeeping missions, proposals to conclude military agreements with the U.N. Security Council under Article 43 of the U.N. Charter, and the applicability of the War Powers Resolution and the U.N. Participation Act. In 1994 and 1995, Congress attempted to gain a greater role in U.N. and other peacekeeping operations through authorization and appropriation legislation. A major element of the House Republicans' Contract with America, H.R. 7 , would have placed notable constraints on presidential authority to commit U.S. forces to international peacekeeping operations. Senator Dole's S. 5 , The Peace Powers Act, introduced in January 1995, would have also placed greater legislative controls on such operations. General and specific funding restrictions and presidential reporting requirements were passed for peacekeeping operations underway or in prospect. Some of these legislative enactments led to presidential vetoes. These representative legislative actions are reviewed below as they apply to given cases.

Persian Gulf War, 1991: How Does the War Powers Resolution Relate to the United Nations and a Real War?

On August 2, 1990, Iraqi troops under the direction of President Saddam Hussein invaded Kuwait, seized its oil fields, installed a new government in Kuwait City, and moved on toward the border with Saudi Arabia. Action to repel the invasion led to the largest war in which the United States had been involved since the passage of the War Powers Resolution. Throughout the effort to repel the Iraqi invasion, President Bush worked in tandem with the United Nations, organizing and obtaining international support and authorization for multilateral military action against Iraq.

A week after the invasion, on August 9, President George H.W. Bush reported to Congress "consistent with the War Powers Resolution" that he had deployed U.S. Armed Forces to the region prepared to take action with others to deter Iraqi aggression. He did not cite Section 4(a)(1) and specifically stated, "I do not believe involvement in hostilities is imminent."

The President did not consult with congressional leaders prior to the deployment, but both houses of Congress had adopted legislation supporting efforts to end the Iraqi occupation of Kuwait, particularly using economic sanctions and multilateral efforts. On August 2, shortly before its recess, the Senate by a vote of 97-0 adopted S.Res. 318 urging the President "to act immediately, using unilateral and multilateral measures, to seek the full and unconditional withdrawal of all Iraqi forces from Kuwaiti territory" and to work for collective international sanctions against Iraq including, if economic sanctions prove inadequate, "additional multilateral actions, under Article 42 of the United Nations Charter, involving air, sea, and land forces as may be needed...." Senate Foreign Relations Committee Chairman Pell stressed, however, that the measure did not authorize unilateral U.S. military actions. Also on August 2, the House passed H.R. 5431 condemning the Iraqi invasion and calling for an economic embargo against Iraq.

The United Nations imposed economic sanctions against Iraq on August 7, and the United States and United Kingdom organized an international naval interdiction effort. Later, on August 25, the U.N. Security Council authorized "such measures as may be necessary" to halt shipping and verify cargoes that might be going to Iraq.

Both Houses adopted measures supporting the deployment, but neither measure was enacted. On October 1, 1990, the House passed H.J.Res. 658 supporting the action and citing the War Powers Resolution without stating that Section 4(a)(1) had become operative. The resolution quoted the President's statement that involvement in hostilities was not imminent. Representative Fascell stated that H.J.Res. 658 was not to be interpreted as a Gulf of Tonkin resolution that granted the President open-ended authority, and that it made clear that "a congressional decision on the issue of war or peace would have to be made through joint consultation." The Senate did not act on H.J.Res. 658 .

On October 2, 1990, the Senate by a vote of 96-3 adopted S.Con.Res. 147 , stating that "Congress supports continued action by the President in accordance with the decisions of the United Nations Security Council and in accordance with United States constitutional and statutory processes, including the authorization and appropriation of funds by the Congress, to deter Iraqi aggression and to protect American lives and vital interest in the region." As in the House, Senate leaders emphasized that the resolution was not to be interpreted as an open-ended resolution similar to the Gulf of Tonkin resolution. The resolution made no mention of the War Powers Resolution. The House did not act on S.Con.Res. 147 . Congress also supported the action by appropriating funds for the preparatory operation, called Operation Desert Shield, and later for war activities called Operation Desert Storm.

Some Members introduced legislation to establish a special consultation group, but the Administration objected to a formally established group. On October 23, 1990, Senate Majority Leader Mitchell announced that he and Speaker Foley had designated Members of the joint bipartisan leadership and committees of jurisdiction to make themselves available as a group for consultation on developments in the Persian Gulf. By this time U.S. land, naval, and air forces numbering more than 200,000 had been deployed.

After the 101 st Congress had adjourned, President Bush on November 8, 1990, ordered an estimated additional 150,000 troops to the Gulf. He incurred considerable criticism because he had not informed the consultation group of the buildup although he had met with them on October 30. On November 16, President Bush sent a second report to Congress describing the continuing and increasing deployment of forces to the region. He stated that his opinion that hostilities were not imminent had not changed. The President wrote, "The deployment will ensure that the coalition has an adequate offensive military option should that be necessary to achieve our common goals." By the end of the year, approximately 350,000 U.S. forces had been deployed to the area.

As the prospect of a war without congressional authorization increased, on November 20, 1990, Representative Ron Dellums and 44 other Democratic Members of Congress sought a judicial order enjoining the President from offensive military operations in connection with Operation Desert Shield unless he consulted with and obtained an authorization from Congress. On November 26, 11 prominent law professors filed a brief in favor of such a judicial action, arguing that the Constitution clearly vested Congress with the authority to declare war and that federal judges should not use the political questions doctrine to avoid ruling on the issue. The American Civil Liberties Union also filed a memorandum in favor of the plaintiffs. On December 13, Judge Harold Greene of the federal district court in Washington denied the injunction, holding that the controversy was not ripe for judicial resolution because a majority of Congress had not sought relief and the executive branch had not shown sufficient commitment to a definitive course of action. However, throughout his opinion Judge Greene rejected the Administration's arguments for full presidential war powers.

On November 29, 1990, U.N. Security Council Resolution 678 authorized member states to use "all necessary means" to implement the Council's resolutions and restore peace and security in the area, unless Iraq complied with the U.N. resolutions by January 15, 1991. As the deadline for Iraqi withdrawal from Kuwait neared, President Bush indicated that if the Iraqi forces did not withdraw from Kuwait, he was prepared to use force to implement the U.N. Security Council resolutions. Administration officials contended that the President did not need any additional congressional authorization for this purpose.

After the 102 nd Congress convened, on January 4, 1991, House and Senate leaders announced they would debate U.S. policy beginning January 10. A week before the January 15 deadline, on January 8, 1991, President Bush, in a letter to the congressional leaders, requested a congressional resolution supporting the use of all necessary means to implement U.N. Security Council Resolution 678. He stated that he was "determined to do whatever is necessary to protect America's security" and that he could "think of no better way than for Congress to express its support for the President at this critical time." It is noteworthy that the President's request for a resolution was a request for congressional "support" for his undertaking in the Persian Gulf, not for "authority" to engage in the military operation. In a press conference on January 9, 1991, President Bush reinforced this distinction in response to questions about the use of force resolution being debated in Congress. He was asked whether he thought he needed the resolution, and if he lost on it would he feel bound by that decision. President Bush in response stated: "I don't think I need it.... I feel that I have the authority to fully implement the United Nations resolutions." He added that he felt that he had "the constitutional authority—many attorneys having so advised me."

On January 12, 1991, both houses passed the "Authorization for Use of Military Force Against Iraq Resolution" ( P.L. 102-1 ). Section 2(a) authorized the President to use U.S. Armed Forces pursuant to U.N. Security Council Resolution 678 to achieve implementation of the earlier Security Council resolutions. Section 2(b) required that first the President would have to report that the United States had used all appropriate diplomatic and other peaceful means to obtain compliance by Iraq with the Security Council resolution and that those efforts had not been successful. Section 2(c) stated that it was intended to constitute specific statutory authorization within the meaning of Section 5(b) of the War Powers Resolution. Section 3 required the President to report every 60 days on efforts to obtain compliance of Iraq with the U.N. Security Council resolution.

In his statement made after signing H.J.Res. 77 into law, President Bush said the following: "As I made clear to congressional leaders at the outset, my request for congressional support did not, and my signing this resolution does not, constitute any change in the long-standing positions of the executive branch on either the President's constitutional authority to use the Armed Forces to defend vital U.S. interests or the constitutionality of the War Powers Resolution." He added that he was pleased that "differences on these issues between the President and many in the Congress have not prevented us from uniting in a common objective."

On January 16, President Bush made the determination required by P.L. 102-1 that diplomatic means had not and would not compel Iraq to withdraw from Kuwait. On January 18, he reported to Congress "consistent with the War Powers Resolution" that he had directed U.S. forces to commence combat operations on January 16.

After the beginning of the war many Members of Congress strongly supported the President as Commander in Chief in his conduct of the war. On March 19, 1991, President Bush reported to Congress that the military operations had been successful, Kuwait had been liberated, and combat operations had been suspended on February 28, 1991.

Prior to passage of P.L. 102-1 , some observers questioned the effectiveness of the War Powers Resolution on grounds that the President had begun the action, deployed hundreds of thousands of troops without consultation of Congress, and was moving the Nation increasingly close to war without congressional authorization. After the passage of P.L. 102-1 and the war had begun, Chairman of the House Committee on Foreign Affairs Fascell took the position that "the War Powers Resolution is alive and well"; the President had submitted reports to Congress, and Congress, in P.L. 102-1 , had provided specific statutory authorization for the use of force. In his view, the strength and wisdom of the War Powers Resolution was that it established a process by which Congress could authorize the use of force in specific settings for limited purposes, short of a total state of war.

The question is sometimes raised why Congress did not declare war against Iraq. Speaker Foley told the National Press Club on February 7, 1991, that "The reason we did not declare a formal war was not because there is any difference I think in the action that was taken and in a formal declaration of war with respect to military operations, but because there is some question about whether we wish to excite or enact some of the domestic consequences of a formal declaration of war—seizure of property, censorship, and so forth, which the President neither sought nor desired."

Iraq-Post Gulf War: How Long Does an Authorization Last?

After the end of Operation Desert Storm, U.S. military forces were used to deal with three continuing situations in Iraq. These activities raised the issue of how long a congressional authorization for the use of force lasts.

The first situation resulted from the Iraqi government's repression of Kurdish and Shi'ite groups. U.N. Security Council Resolution 688 of April 5, 1991, condemned the repression of the Iraqi civilian population and appealed for contributions to humanitarian relief efforts. On May 17, 1991, President George H.W. Bush reported to Congress that the Iraqi repression of the Kurdish people had necessitated a limited introduction of U.S. forces into northern Iraq for emergency relief purposes. On July 16, 1991, he reported that U.S. forces had withdrawn from northern Iraq but that the U.S. remained prepared to take appropriate steps as the situation required and that, to this end, an appropriate level of forces would be maintained in the region for "as long as required."

A second situation stemmed from the cease-fire resolution, Security Council Resolution 687 of April 3, 1991, which called for Iraq to accept the destruction or removal of chemical and biological weapons and international control of its nuclear materials. On September 16, 1991, President Bush reported to Congress that Iraq continued to deny inspection teams access to weapons facilities and that this violated the requirements of Resolution 687, and the United States if necessary would take action to ensure Iraqi compliance with the Council's decisions. He reported similar noncooperation on January 14, 1992, and May 15, 1992.

On July 16, 1992, President Bush reported particular concern about the refusal of Iraqi authorities to grant U.N. inspectors access to the Agricultural Ministry. The President consulted congressional leaders on July 27, and in early August the United States began a series of military exercises to take 5,000 U.S. troops to Kuwait. On September 16, 1992, the President reported, "We will remain prepared to use all necessary means, in accordance with U.N. Security Council resolutions, to assist the United Nations in removing the threat posed by Iraq's chemical, biological, and nuclear weapons capability."

The third situation was related to both of the earlier ones. On August 26, 1992, the United States, Britain, and France began a "no-fly" zone, banning Iraqi fixed wing and helicopter flights south of the 32 nd parallel and creating a limited security zone in the south, where Shi'ite groups were concentrated. After violations of the no-fly zones and various other actions by Iraq, on January 13, 1993, the Bush Administration announced that aircraft from the United States and coalition partners had attacked missile bases in southern Iraq and that the United States was deploying a battalion task force to Kuwait to underline the U.S. continuing commitment to Kuwait's independence. On January 19, 1993, President Bush reported to Congress that U.S. aircraft had shot down an Iraqi aircraft on December 27, 1992, and had undertaken further military actions on January 13, 17, and 18.

President Clinton said on January 21, 1993, that the United States would adhere to the policy toward Iraq set by the Bush Administration. On January 22 and 23, April 9 and 18, June 19, and August 19, 1993, U.S. aircraft fired at targets in Iraq after pilots sensed Iraqi radar or anti-aircraft fire directed at them. On September 23, 1993, President Clinton reported that since the August 19 action, the Iraqi installation fired upon had not displayed hostile intentions.

In a separate incident, on June 28, 1993, President Clinton reported to Congress "consistent with the War Powers Resolution" that on June 26 U.S. naval forces at his direction had launched a Tomahawk cruise missile strike on the Iraqi Intelligence Service's main command and control complex in Baghdad and that the military action was completed upon the impact of the missiles. He said the Iraqi Intelligence Service had planned the failed attempt to assassinate former President Bush during his visit to Kuwait in April 1993.

The question was raised as to whether the Authorization for the Use of Force in Iraq ( P.L. 102-1 ) authorized military actions after the conclusion of the war. P.L. 102-1 authorized the President to use U.S. Armed Forces pursuant to U.N. Security Council Resolution 678 to achieve implementation of previous Security Council Resolutions relating to Iraq's invasion of Kuwait. The cease-fire resolution, Security Council Resolution 687, was adopted afterwards and therefore not included in Resolution 678.

Congress endorsed the view that further specific authorization was not required for U.S. military action to maintain the cease-fire agreement. Specifically, Section 1095 of P.L. 102-190 stated the sense of Congress that it supported the use of all necessary means to achieve the goals of Security Council Resolution 687 as being consistent with the Authorization for Use of Military Force Against Iraq Resolution. Section 1096 supported the use of all necessary means to protect Iraq's Kurdish minority, consistent with relevant U.N. resolutions and authorities contained in P.L. 102-1 . The issue of congressional authorization was debated again in 1998. On March 31, 1998, the House passed a Supplemental Appropriations bill ( H.R. 3579 ) that would have banned the use of funds appropriated in it for the conduct of offensive operations against Iraq, unless such operations were specifically authorized by law. This provision was dropped in the conference with the Senate.

A more broad-gauged approach to the issue of congressional authorization of military force was attempted in mid-1998. On June 24, 1998, the House passed H.R. 4103 , the Defense Department Appropriations bill for FY1999, with a provision by Representative David Skaggs that banned the use of funds appropriated or otherwise made available by this act "to initiate or conduct offensive military operations by United States Armed Forces except in accordance with the war powers clause of the Constitution (Article 1, Section 8), which vests in Congress the power to declare and authorize war and to take certain specified, related actions." The Skaggs provision was stricken by the House-Senate conference committee on H.R. 4103 .

As events developed, beginning in late 1998, and continuing into the period prior to the U.S. military invasion of Iraq in March 2003, the United States conducted a large number of ad-hoc air attacks against Iraqi ground installations and military targets in response to violations of the northern and southern "no-fly zones" by the Iraqis, and threatening actions taken against U.S. and coalition aircraft enforcing these "no-fly" sectors. Congressional authorization to continue these activities was not sought by the President, nor were these many incidents reported under the War Powers Resolution. The "no-fly zones" activities were terminated following the 2003 War with Iraq.

Somalia: When Does Humanitarian Assistance Require Congressional Authorization?

In Somalia, the participation of U.S. military forces in a U.N. operation to protect humanitarian assistance became increasingly controversial as fighting and casualties increased and the objectives of the operation appeared to be expanding.

On December 4, 1992, President George H.W. Bush ordered thousands of U.S. military forces to Somalia to protect humanitarian relief from armed gangs. Earlier, on November 25, the President had offered U.S. forces, and on December 3, the United Nations Security Council had adopted Resolution 794 welcoming the U.S. offer and authorizing the Secretary-General and members cooperating in the U.S. offer "to use all necessary means to establish as soon as possible a secure environment for humanitarian relief operations in Somalia." The resolution also called on member states to provide military forces and authorized the Secretary-General and the states concerned to arrange for unified command and control.

On December 10, 1992, President Bush reported to Congress "consistent with the War Powers Resolution" that on December 8, U.S. Armed Forces entered Somalia to secure the air field and port facility of Mogadishu and that other elements of the U.S. Armed Forces were being introduced into Somalia to achieve the objectives of U.N. Security Council Resolution 794. He said the forces would remain only as long as necessary to establish a secure environment for humanitarian relief operations and would then turn over responsibility for maintaining this environment to a U.N. peacekeeping force. The President said that it was not intended that the U.S. Armed Forces become involved in hostilities, but that the forces were equipped and ready to take such measures as might be needed to accomplish their humanitarian mission and defend themselves. They would also have the support of any additional U.S. forces necessary. By mid-January, U.S. forces in Somalia numbered 25,000.

Since the President did not cite Section 4(a)(1), the 60-day time limit was not necessarily triggered. By February, however, the U.S. force strength was being reduced, and it was announced the United States expected to turn over responsibility for protecting humanitarian relief shipments in Somalia to a U.N. force that would include U.S. troops. On March 26, 1993, the Security Council adopted Resolution 814 expanding the mandate of the U.N. force and bringing about a transition from a U.S.-led force to a U.N.-led force (UNOSOM II). By the middle of May, when the change to U.N. control took place, the U.S. forces were down to approximately 4,000 troops, primarily logistics and communications support teams, but also a rapid deployment force of U.S. Marines stationed on Navy ships.

Violence within Somalia began to increase again. On June 5, 1993, attacks killed 23 Pakistani peacekeepers, and a Somali regional leader, General Aidid, was believed responsible. The next day the U.N. Security Council adopted Resolution 837 reaffirming the authority of UNOSOM II to take all necessary measures against those responsible for the armed attacks. On June 10, 1993, President Clinton reported "consistent with the War Powers Resolution" that the U.S. Quick Reaction Force had executed military strikes to assist UNOSOM II in quelling violence against it. On July 1, President Clinton submitted another report, not mentioning the War Powers Resolution, describing further air and ground military operations aimed at securing General Aidid's compound and neutralizing military capabilities that had been an obstacle to U.N. efforts to deliver humanitarian relief and promote national reconstruction.

From the beginning, a major issue for Congress was whether to authorize U.S. action in Somalia. On February 4, 1993, the Senate had passed S.J.Res. 45 that would authorize the President to use U.S. Armed Forces pursuant to U.N. Security Council Resolution 794. S.J.Res. 45 stated it was intended to constitute the specific statutory authorization under Section 5(b) of the War Powers Resolution. On May 25, 1993, the House amended S.J.Res. 45 to authorize U.S. forces to remain for one year. S.J.Res. 45 was then sent to the Senate for its concurrence, but the Senate did not act on the measure.

As sporadic fighting resulted in the deaths of Somali and U.N. forces, including Americans, controversy over the operation intensified, and Congress took action through other legislative channels. In September 1993 the House and Senate adopted amendments to the Defense Authorization Act for FY1994 asking that the President consult with Congress on policy toward Somalia, and report the goals, objectives, and anticipated jurisdiction of the U.S. mission in Somalia by October 15, 1993; the amendments expressed the sense that the President by November 15, 1993, should seek and receive congressional authorization for the continued deployment of U.S. forces to Somalia. On October 7, the President consulted with congressional leaders from both parties for over two hours on Somalia policy. On October 13, President Clinton sent a 33-page report to Congress on his Somalia policy and its objectives.

Meanwhile, on October 7 President Clinton said that most U.S. forces would be withdrawn from Somalia by March 31, 1994. To ensure this, the Defense Department Appropriations Act for FY1994, cut off funds for U.S. military operations in Somalia after March 31, 1994, unless the President obtained further spending authority from Congress. Congress approved the use of U.S. military forces in Somalia only for the protection of American military personnel and bases and for helping maintain the flow of relief aid by giving the U.N. forces security and logistical support; it required that U.S. combat forces in Somalia remain under the command and control of U.S. commanders under the ultimate direction of the President.

Earlier, some Members suggested that the U.S. forces in Somalia were clearly in a situation of hostilities or imminent hostilities, and that if Congress did not authorize the troops to remain, the forces should be withdrawn within 60 to 90 days. After a letter from House Foreign Affairs Committee Ranking Minority Member Benjamin Gilman and Senate Foreign Relations Committee Ranking Minority Member Jesse Helms, Assistant Secretary Wendy Sherman replied on July 21, 1993, that no previous Administrations had considered that intermittent military engagements, whether constituting hostilities, would necessitate the withdrawal of forces pursuant to Section 5(b); and the War Powers Resolution, in their view, was intended to apply to sustained hostilities. The State Department did not believe congressional authorization was necessary, although congressional support would be welcome. On August 4, 1993, Representative Gilman asserted that August 4 might be remembered as the day the War Powers Resolution died because combat broke out in Somalia on June 5 and the President had not withdrawn U.S. forces and Congress had "decided to look the other way." On October 22, 1993, Representative Gilman introduced H.Con.Res. 170 directing the President pursuant to Section 5(c) of the War Powers Resolution to withdraw U.S. forces from Somalia by January 31, 1994. The House adopted an amended version calling for withdrawal by March 31, 1994. The Senate did not act on this nonbinding measure.

However, the Defense Appropriations Act for FY1995 ( P.L. 103-335 , signed September 30, 1994) prohibited the use of funds for the continuous presence of U.S. forces in Somalia, except for the protection of U.S. personnel, after September 30, 1994. Subsequently, on November 4, 1994, the U.N. Security Council decided to end the U.N. mission in Somalia by March 31, 1995. On March 3, 1995, U.S. forces completed their assistance to United Nations forces evacuating Somalia.

Another war powers issue was the adequacy of consultation before the dispatch of forces. On December 4, 1992, President Bush had met with a number of congressional leaders to brief them on the troop deployment. In his December 10 report, President Bush stressed that he had taken into account the views expressed in H.Con.Res. 370 , S.Con.Res. 132 , and P.L. 102-274 on the urgent need for action in Somalia. However, none of these resolutions explicitly authorized U.S. military action.

Former Yugoslavia/Bosnia/Kosovo: What If No Consensus Exists?

The issue of war powers and U.S. participation in United Nations actions was also raised by efforts to halt fighting in the territory of former Yugoslavia, initially in Bosnia. Because some of the U.S. action has been taken within a NATO framework, action in Bosnia has also raised the issue of whether action under NATO is exempt from the requirements of the War Powers Resolution or its standard for the exercise of war powers under the Constitution. Article 11 of the North Atlantic Treaty states that its provisions are to be carried out by the parties "in accordance with their respective constitutional processes," inferring some role for Congress in the event of war. Section 8(a) of the War Powers Resolution states that authority to introduce U.S. forces into hostilities is not to be inferred from any treaty, ratified before or after 1973, unless implementing legislation specifically authorizes such introduction and says it is intended to constitute an authorization within the meaning of the War Powers Resolution. Section 8(b) states that nothing in the War Powers Resolution should be construed to require further authorization for U.S. participation in the headquarters operations of military commands established before 1973, such as NATO headquarters operations.

On August 13, 1992, the U.N. Security Council adopted Resolution 770 calling on nations to take "all measures necessary" to facilitate the delivery of humanitarian assistance to Sarajevo. Many in Congress had been advocating more assistance to the victims of the conflict. On August 11, 1992, the Senate had passed S.Res. 330 urging the President to work for a U.N. Security Council resolution such as was adopted, but saying that no U.S. military personnel should be introduced into hostilities without clearly defined objectives. On the same day, the House passed H.Res. 554 urging the Security Council to authorize measures, including the use of force, to ensure humanitarian relief.

During 1993 the United States participated in airlifts into Sarajevo, naval monitoring of sanctions, and aerial enforcement of a "no-fly zone." On February 10, 1993, Secretary of State Warren Christopher announced that under President Clinton, the United States would try to convince the Serbs, Muslims, and Croats to pursue a diplomatic solution and that if an agreement was reached, U.S. forces, including ground forces, would help enforce the peace. On February 28, 1993, the United States began an airdrop of relief supplies aimed at civilian populations, mainly Muslims, surrounded by fighting in Bosnia.

On March 31, 1993, the U.N. Security Council authorized member states to take all necessary measures to enforce the ban on military flights over Bosnia, the "no-fly zone." NATO planes, including U.S. planes, began patrolling over Bosnia and Herzegovina on April 12, 1993, to enforce the Security Council ban, and the next day, President Clinton reported the U.S. participation "consistent with Section 4 of the War Powers Resolution."

Conflict continued, but the situation was complicated and opinion in Congress and among U.N. and NATO members was divided. President Clinton consulted with about two dozen congressional leaders on potential further action on April 27 and received a wide range of views. On May 2, the Administration began consultation with allies to build support for additional military action to enforce a cease-fire and Bosnian Serb compliance with a peace agreement, but a consensus on action was not reached.

On June 10, 1993, Secretary of State Christopher announced the United States would send 300 U.S. troops to join 700 Scandinavians in the U.N. peacekeeping force in Macedonia. The mission was established under U.N. Security Council Resolution 795 (1992), which sought to prevent the war in Bosnia from spilling over to neighboring countries. President Clinton reported this action "consistent with Section 4 of the War Powers Resolution" on July 9, 1993. He identified U.S. troops as part of a peacekeeping force, and directed in accordance with Section 7 of the U.N. Participation Act.

Planning for U.N. and NATO action to implement a prospective peace agreement included the possibility that the United States might supply 25,000 out of 50,000 NATO forces to enforce U.N. decisions. This possibility brought proposals to require congressional approval before the dispatch of further forces to Bosnia. On September 23, 1993, Senate Minority Leader Robert Dole said he intended to offer an amendment stating that no additional U.S. forces should be introduced into former Yugoslavia without advance approval from Congress. Assistant Secretary of State Stephen Oxman said on October 5 that the Clinton Administration would consult with Congress and not commit American troops to the implementation operation for a peace agreement without congressional support, and that the Administration would act consistent with the War Powers Resolution. Congress sought to assure this in Section 8146 of P.L. 103-139 , the Defense Appropriations Act for FY1994, stating the sense of Congress that funds should not be available for U.S. forces to participate in new missions or operations to implement the peace settlement in Bosnia unless previously authorized by Congress. This provision was sponsored by the Senate by leaders Mitchell and Dole.

At the NATO summit conference in Brussels on January 11, 1994, leaders, including President Clinton, repeated an August threat to undertake air strikes on Serb positions to save Sarajevo and to consider other steps to end the conflict in Bosnia. On February 17, 1994, President Clinton reported "consistent with" the War Powers Resolution that the United States had expanded its participation in United Nations and NATO efforts to reach a peaceful solution in former Yugoslavia and that 60 U.S. aircraft were available for participation in the authorized NATO missions. On March 1, 1994, he reported that on the previous day U.S. planes patrolling the "no-fly zone" under the North Atlantic Treaty Organization (NATO) shot down 4 Serbian Galeb planes. On April 12, 1994, the President reported that on April 10 and 11, following shelling of Gorazde, one of the "safe areas," and a decision by U.N. and NATO leaders, U.S. planes bombed Bosnian Serbian nationalist positions around Gorazde. On August 22, 1994, President Clinton similarly reported that on August 5, U.S. planes under NATO had strafed a Bosnian Serb gun position in an exclusion zone. On September 22, 1994, two British and one U.S. aircraft bombed a Serbian tank in retaliation for Serb attacks on U.N. peacekeepers near Sarajevo; and on November 21 more than 30 planes from the United States, Britain, France, and the Netherlands bombed the runway of a Serb airfield in Croatia.

As the conflict in Bosnia continued, leaders in Congress called for greater congressional involvement in decisions. Senator Dole introduced S. 2042 , calling for the United States to end unilaterally its arms embargo, conducted in accordance with a U.N. Security Council Resolution, against Bosnia and Herzegovina. On May 10, 1994, Senate Majority Leader George Mitchell introduced an amendment to authorize and approve the President's decision to carry out NATO decisions to support and protect UNPROFOR forces around designated safe areas; to use airpower in the Sarajevo region; and to authorize air strikes against Serb weapons around certain safe areas if these areas were attacked. The Mitchell amendment favored lifting the arms embargo but not unilaterally; it also stated no U.S. ground combat troops should be deployed in Bosnia unless previously authorized by Congress. The Senate adopted both the Dole proposal, as an amendment, and the Mitchell amendment on May 12, 1994, by votes of 50-49. The less stringent Mitchell amendment passed on a straight party line vote. Yet thirteen Democrats voted for the Dole amendment, indicating a sentiment in both parties to assist the Bosnians in defending themselves. The Senate then adopted S. 2042 as amended. The House did not act on the measure.

The Defense Authorization Act for FY1995 ( P.L. 103-337 , signed October 5, 1994) provided, in Section 1404, the sense of the Congress that if the Bosnian Serbs did not accept the Contact Group proposal by October 15, 1994, the President should introduce a U.N. Security Council resolution to end the arms embargo by December 1, 1994; if the Security Council had not acted by November 15, 1994, no funds could be used to enforce the embargo other than those required of all U.N. members under Security Council Resolution 713. That sequence of events occurred and the United States stopped enforcing the embargo. In addition, Section 8100 of the Defense Appropriations Act, FY1995 ( P.L. 103-335 , signed September 30, 1994), stated the sense of the Congress that funds made available by this law should not be available for the purposes of deploying U.S. Armed Forces to participate in implementation of a peace settlement in Bosnia unless previously authorized by Congress.

On May 24, 1995, President Clinton reported "consistent with the War Powers Resolution" that U.S. combat-equipped fighter aircraft and other aircraft continued to contribute to NATO's enforcement of the no-fly zone in airspace over Bosnia-Herzegovina. U.S. aircraft, he noted, are also available for close air support of U.N. forces in Croatia. Roughly 500 U.S. soldiers were still deployed in the former Yugoslav Republic of Macedonia as part of the U.N. Preventive Deployment Force (UNPREDEP). U.S. forces continue to support U.N. refugee and embargo operations in this region.

On September 1, 1995, President Clinton reported "consistent with the War Powers Resolution," that "U.S. combat and support aircraft" had been used beginning on August 29, 1995, in a series of NATO air strikes against Bosnian Serb Army (BSA) forces in Bosnia-Herzegovina that were threatening the U.N.-declared safe areas of Sarajevo, Tuzla, and Gorazde." He noted that during the first day of operations, "some 300 sorties were flown against 23 targets in the vicinity of Sarajevo, Tuzla, Gorazde, and Mostar."

On September 7, 1995, the House passed an amendment to the FY1996 Department of Defense Appropriations Bill ( H.R. 2126 ), offered by Representative Mark Neumann that prohibited the obligation or expenditure of funds provided by the bill for any operations beyond those already undertaken. However, in conference the provision was softened to a sense-of-the-Congress provision that said that President must consult with Congress before deploying U.S. forces to Bosnia. The conference report was rejected by the House over issues unrelated to Bosnia on September 29, 1995, by a vote of 151-267. The substitute conference report on H.R. 2126 , which was subsequently passed and signed into law, did not include language on Bosnia, in part due to the President's earlier objections to any provision in the bill that might impinge on his powers as Commander in Chief. On September 29, the Senate passed by a vote of 94-2 a sense-of-the-Senate amendment to H.R. 2076 , the FY1996 State, Commerce, Justice Appropriations bill, sponsored by Senator Judd Gregg that said no funds in the bill should be used for the deployment of U.S. combat troops to Bosnia-Herzegovina unless Congress approves the deployment in advance or to evacuate endangered U.N. peacekeepers. The conference report on H.R. 2076 , agreed to by the House and the Senate, included the "sense of the Senate" language of the Gregg amendment.

In response to mounting criticism of the Administration's approach to Bosnian policy, on October 17-18, 1995, Secretary of State Christopher, Secretary of Defense Perry and Joint Chiefs of Staff Chairman Shalikashvili testified before House and Senate Committees on Bosnia policy and the prospect of President Clinton deploying approximately 20,000 American ground forces as part of a NATO peacekeeping operation. During testimony before the Senate Foreign Relations Committee on October 17, Secretary Christopher stated that the President would not be bound by a resolution of the Congress prohibiting sending of U.S. forces into Bosnia without the express prior approval of Congress. Nevertheless, on October 19, 1995, President Clinton in a letter to Senator Robert C. Byrd stated that "[w]hile maintaining the constitutional authorities of the Presidency, I would welcome, encourage and, at the appropriate time, request an expression of support by the Congress" for the commitment of U.S. troops to a NATO implementation force in Bosnia, after a peace agreement is reached.

Subsequently, on October 30, 1995, the House, by a vote of 315-103, passed H.Res. 247 , expressing the sense of the House that "no United States Armed forces should be deployed on the ground in the territory of the Republic of Bosnia and Herzegovina to enforce a peace agreement until the Congress has approved such a deployment." On November 13, President Clinton's 9-page letter to Speaker Gingrich stated he would send a request "for a congressional expression of support for U.S. participation in a NATO-led Implementation Force in Bosnia ... before American forces are deployed in Bosnia." The President said there would be a "timely opportunity for Congress to consider and act upon" his request for support. He added that despite his desire for congressional support, he "must reserve" his "constitutional prerogatives in this area." On November 17, 1995, the House passed (243-171) H.R. 2606 , which would "prohibit the use of funds appropriated or otherwise available" to the Defense Department from "being used for the deployment on the ground of United States Armed Forces in the Republic of Bosnia-Herzegovina as part of any peacekeeping operation or as part of any implementation force, unless funds for such deployment are specifically appropriated" by law.

On December 4, 1995, Secretary of Defense Perry announced the deployment of about 1,400 U.S. military personnel (700 to Bosnia/700 to Croatia) as part of the advance elements of the roughly 60,000 person NATO Implementation Force in Bosnia, scheduled to deploy in force once the Dayton Peace Agreement is signed in Paris on December 14, 1995. Secretary Perry noted that once the NATO I-Force was fully deployed, about 20,000 U.S. military personnel would be in Bosnia, and about 5,000 in Croatia.

On December 6, 1995, President Clinton notified the Congress, "consistent with the War Powers Resolution," that he had "ordered the deployment of approximately 1,500 U.S. military personnel to Bosnia and Herzegovina and Croatia as part of a NATO 'enabling force' to lay the groundwork for the prompt and safe deployment of the NATO-led Implementation Force (IFOR)," which would be used to implement the Bosnian peace agreement after its signing. The President also noted that he had authorized deployment of roughly 3,000 other U.S. military personnel to Hungary, Italy, and Croatia to establish infrastructure for the enabling force and the IFOR.

In response to these developments, Congress addressed the question of U.S. ground troop deployments in Bosnia. Lawmakers sought to take action before the final Bosnian peace agreement was signed in Paris on December 14, 1995, following which the bulk of American military forces would be deployed to Bosnia. On December 13, 1995, the House considered H.R. 2770 , sponsored by Representative Dornan, which would have prohibited the use of federal funds for the deployment "on the ground" of U.S. Armed Forces in Bosnia-Herzegovina "as part of any peacekeeping operation, or as part of any implementation force." H.R. 2770 was defeated in the House by a vote of 210-218. On December 13, the House considered two other measures. It approved H.Res. 302 , offered by Representative Buyer, by a vote of 287-141. H.Res. 302 , a nonbinding measure, reiterated "serious concerns and opposition" to the deployment of U.S. ground troops to Bosnia, while expressing confidence, "pride and admiration" for U.S. soldiers deployed there. It called on the President and Defense Secretary to rely on the judgement of the U.S. ground commander in Bosnia and stated that he should be provided with sufficient resources to ensure the safety and well-being of U.S. troops. H.Res. 302 , further stated that the U.S. government should "in all respects" be "impartial and evenhanded" with all parties to the Bosnian conflict "as necessary to ensure the safety and protection" of American forces in the region.

Subsequently, the House defeated H.Res. 306 , proposed by Representative Hamilton, by a vote of 190-237. H.Res. 306 stated that the House "unequivocally supports the men and women of the United States Armed Forces who are carrying out their mission in support of peace in Bosnia and Herzegovina with professional excellence, dedicated patriotism and exemplary bravery."

On December 13, the Senate also considered three measures related to Bosnia and U.S. troop deployments. The Senate defeated H.R. 2606 by a vote of 22-77. This bill would have prohibited funds to be obligated or expended for U.S. participation in peacekeeping in Bosnia unless such funds were specifically appropriated for that purpose. The Senate also defeated S.Con.Res. 35 , a nonbinding resolution of Senators Hutchison and Inhofe. This resolution stated that "Congress opposes President Clinton's decision to deploy" U.S. troops to Bosnia, but noted that "Congress strongly supports" the U.S. troops sent by the President to Bosnia.

The Senate did pass S.J.Res. 44 , sponsored by Senators Dole and McCain, by a vote of 69-30. This resolution stated that Congress "unequivocally supports the men and women of our Armed Forces" who were to be deployed to Bosnia. S.J.Res. 44 stated that "notwithstanding reservations expressed about President Clinton's decision" to deploy U.S. forces, "the President may only fulfill his commitment" to deploy them to Bosnia "for approximately one year" if he made a determination to Congress that the mission of the NATO peace implementation force (IFOR) will be limited to implementing the military annex to the Bosnian peace agreement and to protecting itself. The presidential determination must also state that the United States will "lead an immediate international effort," separate from IFOR, "to provide equipment, arms, training and related logistics assistance of the highest possible quality" to the Muslim-Croat Federation so that it may provide for its own defense. The President could use "existing military drawdown authorities and requesting such additional authority as may be necessary." S.J.Res. 44 also required President Clinton to submit to Congress a detailed report on the armament effort within 30 days, and required regular presidential reports to Congress on the implementation of both the military and nonmilitary aspects of the peace accords.

The House and Senate did not appoint and direct conferees to meet to reconcile the conflicting elements of the Bosnia related measures each had passed on December 13, 1995. A number of Members and Senators had wished to express their views on the troop deployment before the Dayton Accords were formally signed in Paris. That action had occurred, and the leadership of both parties apparently believed nothing further would be achieved by a conference on the measures passed. As result, no final consensus on a single specific measure was reached on the issue by the two chambers.

The President meanwhile continued with the Bosnian deployment. On December 21, 1995, President Clinton notified Congress "consistent with the War Powers Resolution," that he had ordered the deployment of approximately 20,000 U.S. military personnel to participate in the NATO-led Implementation Force (IFOR) in the Republic of Bosnia-Herzegovina, and approximately 5,000 U.S. military personnel would be deployed in other former Yugoslav states, primarily in Croatia. In addition, about 7,000 U.S. support forces would be deployed to Hungary, Italy, Croatia, and other regional states in support of IFOR's mission. The President ordered participation of U.S. forces "pursuant to" his "constitutional authority to conduct the foreign relations of the United States and as Commander-in-Chief and Chief Executive." Subsequently, President Clinton in December 1996, agreed to provide up to 8,500 ground troops to participate in a NATO-led follow-on force in Bosnia termed the Stabilization Force (SFOR). On March 18, 1998, the House defeated by a vote of 193-225, H.Con.Res. 227 , a resolution of Representative Tom Campbell, directing the President, pursuant to Section 5(c) of the War Powers Resolution to remove United States Armed Forces from the Republic of Bosnia and Herzegovina ( H.Rept. 105-442 ).

The issue of presidential authority to deploy forces in the absence of congressional authorization, under the War Powers Resolution, or otherwise, became an issue of renewed controversy in late March 1999 when President Clinton ordered U.S. military forces to participate in a NATO-led military operation in Kosovo. This action was the focus of a major policy debate over the purpose and scope of U.S. military involvement in Kosovo. The President's action to commit forces to the NATO Kosovo operation also led to a suit in federal District Court for the District of Columbia by Members of Congress seeking a judicial finding that the President was violating the War Powers Resolution and the Constitution by using military forces in Yugoslavia in the absence of authorization from the Congress.

The Kosovo controversy began in earnest when on March 26, 1999, President Clinton notified Congress "consistent with the War Powers Resolution," that on March 24, 1999, U.S. military forces, at his direction and in coalition with NATO allies, had commenced air strikes against Yugoslavia in response to the Yugoslav government's campaign of violence and repression against the ethnic Albanian population in Kosovo. Prior to the President's action, the Senate, on March 23, 1999, had passed, by a vote of 58-41, S.Con.Res. 21 , a nonbinding resolution expressing the sense of the Congress that the President was authorized to conduct "military air operations and missile strikes in cooperation with our NATO allies against the Federal Republic of Yugoslavia (Serbia and Montenegro)."

Subsequently, the House voted on a number of measures relating to U.S. participation in the NATO operation in Kosovo. On April 28, 1999, the House of Representatives passed H.R. 1569 , by a vote of 249-180. This bill would prohibit the use of funds appropriated to the Defense Department from being used for the deployment of "ground elements" of the U.S. Armed Forces in the Federal Republic of Yugoslavia unless that deployment is specifically authorized by law. On that same day the House defeated H.Con.Res. 82 , by a vote of 139-290. This resolution would have directed the President, pursuant to Section 5(c) of the War Powers Resolution, to remove U.S. Armed Forces from their positions in connection with the present operations against the Federal Republic of Yugoslavia. On April 28, 1999, the House also defeated H.J.Res. 44 , by a vote of 2-427. This joint resolution would have declared a state of war between the United States and the "Government of the Federal Republic of Yugoslavia." The House on that same day also defeated, on a 213-213 tie vote, S.Con.Res. 21 , the Senate resolution passed on March 23, 1999, that supported military air operations and missile strikes against Yugoslavia. On April 30, 1999, Representative Tom Campbell and 17 other members of the House filed suit in federal District Court for the District of Columbia seeking a ruling requiring the President to obtain authorization from Congress before continuing the air war, or taking other military action against Yugoslavia.

The Senate, on May 4, 1999, by a vote of 78-22, tabled S.J.Res. 20 , a joint resolution, sponsored by Senator John McCain, that would authorize the President "to use all necessary force and other means, in concert with United States allies, to accomplish United States and North Atlantic Treaty Organization objectives in the Federal Republic of Yugoslavia (Serbia and Montenegro)." The House, meanwhile, on May 6, 1999, by a vote of 117-301, defeated an amendment by Representative Ernest Istook to H.R. 1664 , the FY1999 defense supplemental appropriations bill, that would have prohibited the expenditure of funds in the bill to implement any plan to use U.S. ground forces to invade Yugoslavia, except in time of war. Congress, meanwhile, on May 20, 1999, cleared for the President's signature, H.R. 1141 , an emergency supplemental appropriations bill for FY1999, that provided billions in funding for the existing U.S. Kosovo operation.

The Senate tabled two other amendments that would have restricted military operations by President Clinton in Kosovo. On May 24, 1999, it tabled, by a vote of 52-48, an amendment offered by Senator Arlen Specter to state that no funds available to the Defense Department may be obligated or expended for the deployment of U.S. ground troops to Yugoslavia unless authorized by a declaration of war or a joint resolution authorizing the use of military force. The Specter amendment did not apply to certain actions, such as rescuing U.S. military personnel or citizens. On May 26, 1999, the Senate tabled an amendment, by a vote of 77-21, offered by Senator Bob Smith to prohibit, effective October 1, 1999, the use of funds for military operations in Yugoslavia unless Congress enacted specific authorization in law for the conduct of these operations.

On May 25, 1999, the 60 th day had passed since the President notified Congress of his actions regarding U.S. participation in military operations in Kosovo. Representative Campbell, and those who joined his suit, noted to the federal Court that this was a clear violation of the language of the War Powers Resolution stipulating a withdrawal of U.S. forces from the area of hostilities after 60 days in the absence of congressional authorization to continue, or a presidential request to Congress for an extra 30 day period to safely withdraw. The President did not seek such a 30 day extension, noting instead his view that the War Powers Resolution is constitutionally defective.

On June 8, 1999, Federal District Judge Paul L. Friedman dismissed the suit of Representative Campbell and others that sought to have the court rule that President Clinton was in violation of the War Powers Resolution and the Constitution by conducting military activities in Yugoslavia without having received prior authorization from Congress. The judge ruled that Representative Campbell and the other congressional plaintiffs lacked legal standing to bring the suit. On June 24, 1999, Representative Campbell appealed the ruling to the U.S. Court of Appeals for the District of Columbia. The appeals court subsequently agreed to hear the case on an expedited basis before Judges Silberman, Randolph, and Tatel. On February 18, 2000, the appeals court affirmed the opinion of the District Court that Representative Campbell and his co-plaintiffs lacked standing to sue the President. On May 18, 2000, Representative Campbell and 30 other Members of Congress appealed this decision to the United States Supreme Court. On October 2, 2000, the United States Supreme Court, without comment, refused to hear the appeal of Representative Campbell, thereby letting stand the holding of the U.S. Court of Appeals.

While Representative Campbell's litigation was continuing, Yugoslavia, on June 10, 1999, agreed to NATO conditions for a cease-fire and withdrawal of Yugoslav military and paramilitary personnel from Kosovo, and the creation of a peacekeeping force (KFOR) which had the sanction of the United Nations. Further, on June 10, 1999, the House of Representatives defeated, by a vote of 328-97, an amendment to H.R. 1401 , the National Defense Authorization Act for FY2000-FY2001, that would have prohibited the use of any Defense Department funding in FY2000 for "military operations in the Federal Republic of Yugoslavia." On that same day, the House approved, by a vote of 270-155, an amendment that deleted, from the House reported version of H.R. 1401 , language that would have prohibited any funding for "combat or peacekeeping operations" in the Federal Republic of Yugoslavia.

On June 12, 1999, President Clinton announced and reported to Congress "consistent with the War Powers Resolution" that he had directed the deployment of about "7,000 U.S. military personnel as the U.S. contribution to the approximately 50,000-member, NATO-led security force (KFOR)" being assembled in Kosovo. He also noted that about "1,500 U.S. military personnel, under separate U.S. command and control, will deploy to other countries in the region, as our national support element, in support of KFOR." Thus, by the summer of 1999, the President had been able to proceed with his policy of intervention in the Kosovo crisis under the aegis of NATO, the Congress had not achieved any position of consensus on what actions were appropriate in Yugoslavia, and a U.S. District Court had dismissed a congressional lawsuit (a position subsequently affirmed the following year by the Appeals Court, and the U.S. Supreme Court) attempting to stop presidential military action in Yugoslavia in the absence of prior congressional authorization under the War Powers Resolution.

Haiti: Can the President Order Enforcement of a U.N. Embargo?

On July 3, 1993, Haitian military leader Raoul Cedras and deposed President Jean-Bertrand Aristide signed an agreement providing for the restoration of President Aristide on October 30. The United Nations and the Organization of American States took responsibility for verifying compliance. In conjunction with the agreement, President Clinton offered to send 350 troops and military engineers to Haiti to help retrain the Haitian armed forces and work on construction projects. A first group of American and Canadian troops arrived on October 6. When additional U.S. forces arrived on October 11, a group of armed civilians appeared intent upon resisting their landing, and on October 12 defense officials ordered the ship carrying them, the U.S.S. Harlan County , to leave Haitian waters.

Because the Haitian authorities were not complying with the agreement, on October 13 the U.N. Security Council voted to restore sanctions against Haiti. On October 20, President Clinton reported "consistent with the War Powers Resolution" that U.S. ships had begun to enforce the U.N. embargo. Some Members of Congress complained that Congress had not been consulted on or authorized the action. On October 18, Senator Dole said he would offer an amendment to the Defense Appropriations bill ( H.R. 3116 ) which would require congressional authorization for all deployments into Haitian waters and airspace unless the President made specified certifications. Congressional leaders and Administration officials negotiated on the terms of the amendment. As enacted, Section 8147 of P.L. 103-139 stated the sense of Congress that funds should not be obligated or expended for U.S. military operations in Haiti unless the operations were (1) authorized in advance by Congress, (2) necessary to protect or evacuate U.S. citizens, (3) vital to the national security of the United States and there was not sufficient time to receive congressional authorization, or (4) the President reported in advance that the intended deployment met certain criteria.

Enforcement of the embargo intensified. On April 20, 1994, President Clinton further reported "consistent with the War Powers Resolution" that U.S. naval forces had continued enforcement in the waters around Haiti and that 712 vessels had been boarded. On May 6, 1994, the U.N. Security Council adopted Resolution 917 calling for measures to tighten the embargo. On June 10, 1994, President Clinton announced steps being taken to intensify the pressure on Haiti's military leaders that included assisting the Dominican Republic to seal its border with Haiti, using U.S. naval patrol boats to detain ships suspected of violating the sanctions, a ban on commercial air traffic, and sanctions on financial transactions.

As conditions in Haiti worsened, President Clinton stated he would not rule out the use of force, and gradually this option appeared more certain. Many Members continued to contend congressional authorization was necessary for any invasion of Haiti. On May 24, 1994, the House adopted the Goss amendment to the Defense Authorization bill ( H.R. 4301 ) by a vote of 223-201. The amendment expressed the sense of Congress that the United States should not undertake any military action against the mainland of Haiti unless the President first certified to Congress that clear and present danger to U.S. citizens or interests required such action. Subsequently, on June 9 the House voted on the Goss amendment again. This time the House reversed itself and rejected the amendment by a vote of 195-226. On June 27, a point of order was sustained against an amendment to the State Department appropriations bill that sought to prohibit use of funds for any U.N. peacekeeping operation related to Haiti. On June 29, 1994, the Senate in action on H.R. 4226 repassed a provision identical to Section 8147 of P.L. 103-139 but rejected a measure making advance congressional authorization a binding requirement. On August 5 it tabled (rejected) by a vote of 31 to 63 an amendment to H.R. 4606 by Senator Specter prohibiting the President from using U.S. Armed Forces to depose the military leadership unless authorized in advance by Congress, necessary to protect U.S. citizens, or vital to U.S. interests.

President Clinton sought and obtained U.N. Security Council authorization for an invasion. On July 31, the U.N. Security Council authorized a multinational force to use "all necessary means to facilitate the departure from Haiti of the military leadership ... on the understanding that the cost of implementing this temporary operation will be borne by the participating Member States" (Resolution 940, 1994).

On August 3, the Senate adopted an amendment to the Department of Veterans Affairs appropriation, H.R. 4624 , by a vote of 100-0 expressing its sense that the Security Council Resolution did not constitute authorization for the deployment of U.S. forces in Haiti under the Constitution or the War Powers Resolution. The amendment, however, was rejected in conference. President Clinton said the same day that he would welcome the support of Congress but did not agree that he was constitutionally mandated to obtain it. Some Members introduced resolutions, such as H.Con.Res. 276 , calling for congressional authorization prior to the invasion.

On September 15, 1994, in an address to the Nation, President Clinton said he had called up the military reserve and ordered two aircraft carriers into the region. His message to the military dictators was to leave now or the United States would force them from power. The first phase of military action would remove the dictators from power and restore Haiti's democratically elected government. The second phase would involve a much smaller force joining with forces from other U.N. members which would leave Haiti after 1995 elections were held and a new government installed.

While the Defense Department continued to prepare for an invasion within days, on September 16 President Clinton sent to Haiti a negotiating team of former President Jimmy Carter, former Joint Chiefs of Staff Chairman Colin Powell, and Senate Armed Services Committee Chairman Sam Nunn. Again addressing the Nation on September 18, President Clinton announced that the military leaders had agreed to step down by October 15, and agreed to the immediate introduction of troops, beginning September 19, from the 15,000 member international coalition. He said the agreement was only possible because of the credible and imminent threat of multinational force. He emphasized the mission still had risks and there remained possibilities of violence directed at U.S. troops, but the agreement minimized those risks. He also said that under U.N. Security Council resolution 940, a 25-nation international coalition would soon go to Haiti to begin the task of restoring democratic government. Also on September 18, President Clinton reported to Congress on the objectives in accordance with the sense expressed in Section 8147 (c) of P.L. 103-139 , the FY1994 Defense Appropriations Act.

U.S. forces entered Haiti on September 1994. On September 21, President Clinton reported "consistent with the War Powers Resolution" the deployment of 1,500 troops, to be increased by several thousand. (At the peak in September there were about 21,000 U.S. forces in Haiti.) He said the U.S. presence would not be open-ended but would be replaced after a period of months by a U.N. peacekeeping force, although some U.S. forces would participate in and be present for the duration of the U.N. mission. The forces were involved in the first hostilities on September 24 when U.S. Marines killed 10 armed Haitian resisters in a fire-fight.

On September 19, the House agreed to H.Con.Res. 290 commending the President and the special delegation to Haiti, and supporting the prompt and orderly withdrawal of U.S. forces from Haiti as soon as possible; on September 19, the Senate agreed to a similar measure, S.Res. 259 . On October 3, 1994, the House Foreign Affairs Committee reported H.J.Res. 416 authorizing the forces in Haiti until March 1, 1995, and providing procedures for a joint resolution to withdraw the forces. In House debate on October 6 the House voted against the original contents and for the Dellums substitute. As passed, H.J.Res. 416 stated the sense that the President should have sought congressional approval before deploying U.S. forces to Haiti, supporting a prompt and orderly withdrawal as soon as possible, and requiring a monthly report on Haiti as well as other reports. This same language was also adopted by the Senate on October 6 as S.J.Res. 229 , and on October 7 the House passed S.J.Res. 229 . President Clinton signed S.J.Res. 229 on October 25, 1994 ( P.L. 103-423 ).

After U.S. forces began to disarm Haitian military and paramilitary forces and President Aristide returned on October 15, 1994, the United States began to withdraw some forces. On March 31, 1995, U.N. peacekeeping forces assumed responsibility for missions previously conducted by U.S. military forces in Haiti. By September 21, 1995, President Clinton reported the United States had 2,400 military personnel in Haiti as participants in the U.N. Mission in Haiti (UNMIH), and 260 U.S. military personnel assigned to the U.S. Support Group Haiti. On February 29, 1996, the U.S. Commander of the UNMIH was replaced and U.S. forces ceased to conduct security operations in Haiti, except for self-defense. The majority of the 1,907 U.S. military personnel in Haiti were withdrawn by mid-March 1996, and the remainder, who stayed to arrange the dismantlement and repatriation of equipment, were withdrawn in mid-April 1996. After that, a U.S. support unit of 300 to 500 troops, made up primarily of engineers, remained in Haiti carrying out public works such as building bridges, repairing schools, and digging wells. In December 1997, President Clinton ordered the Dept. of Defense to maintain hundreds of U.S. troops in Haiti indefinitely. In September 1999, however, the 106 th Congress passed the FY2000 DOD authorization bill ( P.L. 106-65 ) that prohibited DOD funding to maintain a continuous U.S. military presence in Haiti beyond May 31, 2000. The troops were withdrawn by the end of January 2000. According to the conference report accompanying the FY2000 DOD authorization bill ( H.Rept. 106-301 ), the President is not prohibited from engaging in periodic theater engagement activities in Haiti.

Terrorist Attacks against the United States (World Trade Center and the Pentagon) 2001: How Does the War Powers Resolution Apply?

On September 11, 2001, terrorists hijacked four U.S. commercial airliners, crashing two into the twin towers of the World Trade Center in New York City, and another into the Pentagon building in Arlington, VA. The fourth plane crashed in Shanksville, PA, near Pittsburgh, after passengers struggled with the highjackers for control of the aircraft. The death toll from these incidents was more than three thousand, making the attacks the most devastating of their kind in United States history. President George W. Bush characterized these attacks as more than acts of terror. "They were acts of war," he said. He added that "freedom and democracy are under attack," and he asserted that the United States would use "all of our resources to conquer this enemy."

In the days immediately after the September 11 attacks, the President consulted with the leaders of Congress on appropriate steps to take to deal with the situation confronting the United States. One of the things that emerged from discussions with the White House and congressional leaders was the concept of a joint resolution of the Congress authorizing the President to take military steps to deal with the parties responsible for the attacks on the United States. Between September 13 and 14, draft language of such a resolution was discussed and negotiated by the President's representatives and the House and Senate leadership of both parties. Other members of both Houses suggested language for consideration. On Friday, September 14, 2001, the text of a joint resolution was introduced. It was first considered and passed by the Senate in the morning of September 14, as Senate Joint Resolution 23, by a vote of 98-0. The House of Representatives passed it later that evening, by a vote of 420-1, after tabling an identical resolution, H.J.Res. 64 , and rejecting a motion to recommit by Representative John Tierney that would have had the effect, if passed and enacted, of requiring a report from the President on his actions under the resolution every 60 days.

Senate Joint Resolution 23, titled the "Authorization for Use of Military Force," passed by Congress on September 14, 2001, was signed into law on September 18, 2001. The joint resolution authorizes the President

to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.

The joint resolution further states that Congress declares that this resolution is intended to "constitute specific statutory authorization within the meaning of section 5(b) of the War Powers Resolution." Finally, the joint resolution also states that "[n]othing in this resolution supercedes any requirement of the War Powers Resolution."

A notable feature of S.J.Res. 23 is that unlike all other major legislation authorizing the use of military force by the President, this joint resolution authorizes military force against "organizations and persons" linked to the September 11, 2001, attacks on the United States. Past authorizations of the use of force have permitted action against unnamed nations in specific regions of the world or against named individual nations. This authorization of military action against "organizations or persons" is unprecedented in American history, with the scope of its reach yet to be determined. The authorization of use of force against unnamed nations is more consistent with some previous instances where authority was given to act against unnamed states as appropriate when they became aggressors or took military action against the United States or its citizens.

President George W. Bush in signing S.J.Res. on September 18, 2001, noted the Congress had acted "wisely, decisively, and in the finest traditions of our country." He thanked the "leadership of both Houses for their role in expeditiously passing this historic joint resolution." He noted that he had had the "benefit of meaningful consultations with members of the Congress" since the September 11 attacks and that he would "continue to consult closely with them as our Nation responds to this threat to our peace and security." President Bush also asserted that S.J.Res. 23 "recognized the authority of the President under the Constitution to take action to deter and prevent acts of terrorism against the United States." He also stated: "In signing this resolution, I maintain the longstanding position of the executive branch regarding the President's constitutional authority to use force, including the Armed Forces of the United States and regarding the constitutionality of the War Powers Resolution."

Prior to its enactment, there was concern among some in Congress that the President might not adhere to the reporting requirements of the War Powers Resolution when he exercised the authority provided in S.J.Res. 23 . There appeared to be general agreement that the President had committed himself to consult with Congress on matters related to his military actions against terrorists and those associated with the attacks on the United States on September 11. On September 24, 2001, President Bush reported to Congress, "consistent with the War Powers Resolution," and "Senate Joint Resolution 23" that in response to terrorist attacks on the World Trade Center and the Pentagon he had ordered the "deployment of various combat-equipped and combat support forces to a number of foreign nations in the Central and Pacific Command areas of operations." The President noted that as part of efforts to "prevent and deter terrorism" he might find it necessary to order additional forces into these and other areas of the world...." He stated that he could not now predict "the scope and duration of these deployments," nor the "actions necessary to counter the terrorist threat to the United States."

Subsequently, on October 9, 2001, President George W. Bush reported to Congress, "consistent with the War Powers Resolution," and "Senate Joint Resolution 23" that on October 7, 2001, U.S. Armed Forces "began combat action in Afghanistan against Al Qaida terrorists and their Taliban supporters." The President stated that he had directed this military action in response to the September 11, 2001, attacks on U.S. "territory, our citizens, and our way of life, and to the continuing threat of terrorist acts against the United States and our friends and allies." This military action was "part of our campaign against terrorism" and was "designed to disrupt the use of Afghanistan as a terrorist base of operations."

Thus, in light of the September 11, 2001, terrorist attacks against United States territory and citizens, the President and Congress, after consultations, agreed to a course of legislative action that did not invoke the War Powers Resolution itself, but substituted a specific authorization measure, S.J.Res. 23 . Pursuit of such an action is contemplated by the language of the War Powers Resolution itself. As of the end of October 2001, President Bush had chosen to state in his reports to Congress that the military actions he had taken relating to the terrorists attacks were "consistent with" both the War Powers Resolution and Senate Joint Resolution 23. His actions follow the practice of his White House predecessors in not formally citing the language of the War Powers Resolution in Section 4(a)(1) that would trigger a military forces withdrawal timetable. Congress for its part in S.J.Res. 23 stated that this legislation constituted "specific statutory authorization within the meaning of section 5(b) of the War Powers Resolution." It also noted that "nothing" in S.J.Res. 23 "supercedes any requirement of the War Powers Resolution." The President and Congress, in sum, maintained their respective positions on the constitutionality of the War Powers Resolution and the responsibilities of the President under it, while finding a legislative vehicle around which both branches could unite to support the President's response to the terrorist attacks on the United States.

Use of Force Against Iraq Resolution 2002: A Classic Application of the War Powers Resolution?

In summer 2002, the Bush Administration made public its views regarding what it deemed a significant threat to U.S. interests and security posed by the prospect that Iraq had or was acquiring weapons of mass destruction. Senior members of the Bush Administration cited a number of violations of U.N. Security Council resolutions by Iraq regarding the obligation imposed at the end of the Gulf War in 1991 to end its chemical, biological and nuclear weapons programs. On September 4, 2002, President George W. Bush met with leaders from both Houses and parties at the White House. At that meeting the President stated that he would seek congressional support, in the near future, for action deemed necessary to deal with the threat posed to the United States by the regime of Saddam Hussein of Iraq. The President also indicated that he would speak to the United Nations shortly and set out his concerns about Iraq.

On September 12, 2002, President Bush addressed the U.N. General Assembly and set out the history of Iraqi misdeeds over the last two decades and the numerous times that Iraq had not fulfilled its commitments to comply with various U.N. Security Council resolutions, including disarmament, since the Gulf War of 1991. He stated that the United States would work with the U.N. Security Council to deal with Iraq's challenge. However, he emphasized that if Iraq refused to fulfill its obligations to comply with U.N. Security Council resolutions, the United States would see that those resolutions were enforced.

Subsequently, on September 19, 2002, the White House sent a "draft" joint resolution to House Speaker Dennis Hastert, House Minority Leader Richard Gephardt, Senate Majority Leader Thomas Daschle and Senate Minority Leader Trent Lott. This draft would have authorized the President to use military force not only against Iraq but "to restore international peace and security in the region." Subsequently introduced as S.J.Res. 45 on September 26, it served as the basis for an extensive debate over the desirability, necessity, and scope of a new congressional authorization for the use of force. The Senate used this bill as the focus for a debate which began, after cloture was invoked, on October 3. The Senate debate continued from October 4 until October 11, 2002, and involved consideration of numerous amendments to the measure. In the end the Senate adopted H.J.Res. 114 in lieu of S.J.Res. 45 .

The draft measure was not formally introduced in the House. Instead, the vehicle for House consideration of the issue was H.J.Res. 114 . Cosponsored by Speaker Hastert and Minority Leader Gephardt and introduced on October 2, 2002, H.J.Res. 114 embodied modifications to the White House draft that were agreeable to the White House, most House and Senate Republicans, and the House Democratic leader. The House International Relations Committee reported out a slightly amended version of the joint resolution on October 7, 2002 ( H.R. 721 ). The House adopted the rule governing debate on the joint resolution ( H.R. 474 ) on October 8, 2002; and debated the measure until October 10, when it passed H.J.Res. 114 by a vote of 296-133. Subsequently, the Senate passed the House version of H.J.Res. 114 on October 11 by a vote of 77-23, and President Bush signed the "Authorization for Use of Military Force against Iraq Resolution of 2002" into law on October 16, 2002.

In signing H.J.Res. 114 into law, President Bush noted that by passing this legislation Congress had demonstrated that "the United States speaks with one voice on the threat to international peace and security posed by Iraq." He added that the legislation carried an important message that "Iraq will either comply with all U.N. resolutions, rid itself of weapons of mass destruction, and ... its support for terrorists, or will be compelled to do so." While the President noted he had sought a "resolution of support" from Congress to use force against Iraq, and appreciated receiving that support, he also stated that

my request for it did not, and my signing this resolution does not, constitute any change in the long-standing positions of the executive branch on either the President's constitutional authority to use force to deter, prevent, or respond to aggression or other threats to U.S. interests or on the constitutionality of the War Powers Resolution.

The President went on to state that on the "important question of the threat posed by Iraq," his views and goals and those of Congress were the same. He further observed that he had extensive consultations with Congress in the past months, and that he looked forward to "continuing close consultation in the months ahead." He stated his intent to submit written reports to Congress every 60 days on matters "relevant to this resolution."

The central element of P.L. 107-243 is the authorization for the President to use the armed forces of the United States

as he determines to be necessary and appropriate in order to (1) defend the national security of the United States against the continuing threat posed by Iraq; and (2) enforce all relevant United Nations Security Council resolutions regarding Iraq.

As predicates for the use of force, the statute requires the President to communicate to Congress his determination that the use of diplomatic and other peaceful means will not "adequately protect the United States ... or ... lead to enforcement of all relevant United Nations Security Council resolutions" and that the use of force is "consistent" with the battle against terrorism. Like P.L. 102-1 and P.L. 107-40 , the statute declares that it is "intended to constitute specific statutory authorization within the meaning of section 5(b) of the War Powers Resolution." It also requires the President to make periodic reports to Congress "on matters relevant to this joint resolution." Finally, the statute expresses Congress' "support" for the efforts of the President to obtain "prompt and decisive action by the Security Council" to enforce Iraq's compliance with all relevant Security Council resolutions.

http://www.congress.gov/cgi-lis/bdquery/R?d107:FLD002:@1(107+243) P.L. 107-243 clearly confers broad authority on the President to use force. In contrast to P.L. 102-1 , the authority granted is not limited to the implementation of previously adopted Security Council resolutions concerning Iraq but includes "all relevant ... resolutions." Thus, it appears to incorporate resolutions concerning Iraq that may be adopted by the Security Council in the future as well as those already adopted. The authority also appears to extend beyond compelling Iraq's disarmament to implementing the full range of concerns expressed in those resolutions. Unlike P.L. 107-40 , the President's exercise of the authority granted is not dependent upon a finding that Iraq was associated in some direct way with the September 11, 2001, attacks on the United States. Moreover, the authority conferred can be used for the broad purpose of defending "the national security of the United States against the continuing threat posed by Iraq." Nevertheless, P.L. 107-243 is narrower than P.L. 107-40 in that it limits the authorization for the use of force to Iraq. It also requires as a predicate for the use of force that the President determine that peaceful means cannot suffice and that the use of force against Iraq is consistent with the battle against terrorism. It further limits the force used to that which the President determines is "necessary and appropriate." Finally, as with P.L. 107-40 , the statutory authorization for use of force granted to the President in P.L. 107-243 is not dependent for its exercise upon prior authorization by the U.N. Security Council. In the form that P.L. 107-243 is drafted, and given the context in which it was debated, one could argue that it is a classic example of an authorization vehicle contemplated by the original War Powers Resolution.

Libya 2011: Establishing a New Definition of What Constitutes "Hostilities" for Purposes of Full Compliance with the War Powers Resolution?

During U.S. military operations in Libya from mid-March through June 2011, President Barack Obama—having received legal advice from the Office of Legal Counsel (OLC) at the Justice Department and State Department Legal Advisor Harold Koh—took the position that U.S. military operations in Libya did not constitute "hostilities" for purposes of the language of the War Powers Resolution nor was the United States involved in a "war" in Libya for purposes of Article I of the Constitution. Given those conclusions by the Administration, the President's view was that express statutory authorization from Congress to conduct the military operations in Libya was not required under the framework of the War Powers Resolution.

The President did comply with the reporting requirements of the War Powers Resolution, when the Libya operation was first launched in March 2011, and followed up with a letter to congressional leaders on May 20, 2011—the 60 th day after U.S. military forces were "introduced" into the conflict in Libya. In his May 20 letter, the President pointed out that on April 4, 2011, the United States had transferred responsibility for military operations in Libya to NATO forces, and that from that time forward the U.S. had assumed only a supporting role for the NATO-led operation. This support included, "since April 23, [36 days after the initial introduction of U.S. military forces into Libya], precision strikes by unmanned aerial vehicles against a limited set of clearly defined targets in support of the NATO-led coalition's efforts." The President held from the outset that the actions he had directed were "in the national security and foreign policy interests of the United States." He took them, the President stated, "pursuant to my constitutional authority to conduct U.S. foreign relations and as Commander in Chief and Chief Executive."

Administration Report to Congress on "United States Activities in Libya" Submitted on June 15, 2011

On June 15, 2011 (86 days after the initial introduction of U.S. military forces into Libya), the Obama Administration submitted a 32-page unclassified report, together with a classified annex, that described U.S. actions in Libya to that date. On page 25 of that unclassified report was a "Legal Analysis" consisting of one long paragraph summarizing the Administration's view of what the President's authority was to take the actions he had taken in Libya, and his rationale for not having to obtain congressional authorization to do so. This paragraph from the report states

Given the important U.S. interests served by U.S. military operations in Libya and the limited nature, scope and duration of the anticipated actions, the President had constitutional authority, as Commander in Chief and Chief Executive and pursuant to his foreign affairs powers, to direct such limited military operations abroad. The President is of the view that the current U.S. military operations in Libya are consistent with the War Powers Resolution and do not under that law require further congressional authorization, because U.S. military operations are distinct from the kind of "hostilities" contemplated by the Resolution's 60 day termination provision. U.S. forces are playing a constrained and supporting role in a multinational coalition, whose operations are both legitimated by and limited to the terms of a United Nations Security Council Resolution that authorizes the use of force solely to protect civilians and civilian populated areas under attack or threat of attack and to enforce a no-fly zone and an arms embargo. U.S. operations do not involve sustained fighting or active exchanges of fire with hostile forces, nor do they involve the presence of U.S. ground troops, U.S. casualties or a serious threat thereof, or any significant chance of escalation into a conflict characterized by these factors.

There are various legal arguments available to the Administration to justify use of UAVs for military action abroad against terrorist organizations and individuals. The following addresses the potential interplay of the War Powers Resolution's statutory requirements and the use of UAVs for military operations abroad.

The War Powers Resolution and Military Use of UAVs: Some Considerations

In another situation, it is possible that the President might use the same basic formulation he and his legal advisors set out regarding the application of the War Powers Resolution to U.S. military actions in Libya discussed above. Directly put, if it is accepted that the President's use of UAVs for military attacks against terrorist targets abroad constitutes an action that is limited in scope and duration, and does not require introduction of U.S. military forces directly and physically into "hostilities," then the War Powers Resolution, under this interpretation, does not apply to this presidential action, nor require congressional statutory authorization. The President, under this construction, has sufficient authority to act to defend the United States based only on his own Constitutional authorities as Commander in Chief, as set out in the legal memorandum of the Office of Legal Counsel of April 1, 2011, and in the President's June 15, 2011, report to Congress.

To date, based on public reports, instances of the use of UAVs to attack terrorist targets abroad have not required a time period in excess of 60 days to execute, nor have U.S. military personnel been placed directly into harm's way or in places where hostilities that could directly involve them were indicated. The very nature of UAV technology permits their employment from locations remote from the places they are used to attack. Thus, the argument could be made that in these circumstances, the War Powers Resolution, as currently drafted, does not require the President to obtain statutory congressional approval for the use of UAVs in military operations abroad.

In his War Powers Resolution report to Congress, on June 15, 2012, the President noted that he had authorized, during the previous six months, the U.S. military to work closely with the government of Yemen "to operationally dismantle and ultimately eliminate the terrorist threat posed by al-Qa'ida in the Arabian Peninsula (AQAP), the most active and dangerous affiliate of al-Qa'ida today." The President added that

Our joint efforts have resulted in direct action against a limited number of AQAP operatives and senior leaders in that country who posed a terrorist threat to the United States and our interests.

While the term "direct action" is not defined in the President's June 15, 2012, report quoted above, its context, coupled with public reporting on the U.S. use of UAVs to attack al-Qa'ida terrorist personnel in Yemen, strongly suggests that this is what the President is referring to in this report. The President further notes in this report that similar actions may be undertaken by the United States in the future. He stated:

The United States is committed to thwarting the efforts of al-Qa'ida and its associated forces to carry out future acts of international terrorism, and we have continued to work with our CT [counter-terrorism] partners to disrupt and degrade the capabilities of al-Qa'ida and its associated forces. As necessary, in response to the terrorist threat, I will direct additional measures against al-Qa'ida, the Taliban, and associated forces to protect U.S. citizens and interests.

The June 15, 2012, report also stated that a "classified annex" to it "would provide further information" on such matters. That annex would perhaps elaborate on the specifics of the topics alluded to in the unclassified text, and clarify the express meaning of "direct action," and, in particular, how it was employed by the United States.

In light of the above considerations, it appears that the existing statutory language of the War Powers Resolution, as interpreted by the Administration, does not require congressional authorization for the President to use UAVs in military operations against terrorists abroad, in Yemen or in other countries. It does appear that the President may believe that in fulfilling his reporting obligations to Congress under the WPR he should at least implicitly note the use of UAVs in military attacks against terrorists when he submits his supplementary WPR report every six months. Perhaps the President also believes he should, in keeping with WPR reporting requirements, report more explicitly about such actions in classified reports every six months. Even though the President has not publicly reported the specific use of UAVs in military operations within 48 hours of their use, private consultations with the congressional leadership about their use may have occurred in individual cases.

Should Congress agree with what appears to be the President's position regarding his minimal obligations under the War Powers Resolution regarding the military use of UAVs, it need do nothing further. However, should Congress conclude that the War Powers Resolution should unambiguously require statutory congressional authorization of the military use of UAVs for counter-terrorism operations, then it would likely have to amend this statute, unless other mutually agreeable alternatives can be devised with the President.

Military Campaign Against the Islamic State

Beginning in June 2014, forces of the Islamic State (IS; also known as ISIL, ISIS, or the Arabic acronym Da' esh ) rapidly expanded their control of several Iraqi cities and threatened attack on Baghdad. These developments caused worries of debilitating destabilization of Iraq's government and increased U.S. concerns for the safety of the U.S. embassy, other U.S. facilities, and U.S. personnel in Iraq, as well as the Iraqi population.

After first ordering multiple deployments of U.S. troops to Iraq to provide security to diplomatic personnel and facilities, advise Iraqi security forces, and conduct intelligence gathering and reconnaissance, President Obama began ordering U.S. military airstrikes on IS forces in Iraq in August 2014. Later in September, after laying out plans for expanded use of military force against the Islamic State in a televised speech to the American people, the President ordered U.S. military airstrikes in Syria against both IS forces and forces of the "Khorasan Group," identified by the President as part of Al Qaeda. U.S. military operations against the Islamic State have since expanded in limited fashion to Libya; targeted anti-IS airstrikes have been detailed in periodic presidential War Powers Resolution reporting to Congress. In addition, it has been reported that the Trump Administration plans a new deployment of approximately 1,000 U.S. troops to Syria, seemingly signaling further expansion of the anti-IS military campaign. U.S. military engagement in hostilities against these groups in Iraq, Syria, and elsewhere has raised numerous questions in Congress and beyond about the President's authority to use military force in this conflict. Questions concerning President Obama's WPR notifications to Congress and his eventual reliance on existing authorizations for use of military force to meet the requirements of the WPR have arisen, and Congress has considered proposals to enact a new authorization for use of military force targeting the Islamic State, including a February 2015 proposal from President Obama. The Trump Administration has continued the previous Administration's reliance on existing AUMFs to conduct the military campaign against the Islamic State, and many Members of Congress remain concerned and active in calling for congressional action to oversee, authorize, or limit presidential authority to continue the use of military force.

Presidential Reporting on Individual Missions and the War Powers Resolution's Withdrawal Requirement

President Obama began providing WPR notifications concerning the U.S. military response in Iraq to the Islamic State crisis in June 2014. On June 16, 2014, President Obama notified the Speaker of the House and President pro tempore of the Senate, "consistent with the War Powers Resolution," that he had deployed combat-equipped troops to Iraq to provide security for U.S. diplomatic personnel and facilities. On August 8, 2014, the President sent the first notification during the current crisis concerning the use of military force in Iraq. Prior to the President's announcement of a wider, sustained military campaign against the Islamic State on September 10, 2014, President Obama made seven WPR notifications for deployments and actions in Iraq, four concerning combat-equipped troop deployments with no hostilities active or imminent, and three concerning airstrikes against ISIL forces

June 16, 2014, Security for U.S. Embassy Baghdad: notification informed Congress of the deployment of up to 275 U.S. Armed Forces personnel to Iraq to provide support and security for U.S. personnel and the U.S. Embassy in Baghdad. June 26, 2014, Military Advisers: notification informed Congress of the deployment of up to approximately 300 additional U.S. Armed Forces personnel in Iraq to "assess how we can best train, advise, and support Iraqi security forces and to establish joint operations centers with Iraqi security forces to share intelligence and coordinate planning to confront the threat posed by ISIL," and for presidential orders to "increase intelligence, surveillance, and reconnaissance that is focused on the threat posed by the Islamic State of Iraq and the Levant (ISIL)." June 30, 2014, Increased Security Deployment: notification informed Congress of the deployment of up to approximately 200 additional U.S. Armed Forces personnel to Iraq to "reinforce security at the U.S. Embassy, its support facilities, and the Baghdad International Airport." August 8, 2014, Airstrikes and Humanitarian Assistance and Intervention: notification informed Congress of airstrikes to protect U.S. personnel in Erbil and to assist a humanitarian mission to protect Iraqi civilians trapped on Mount Sinjar in northern Iraq. August 17, 2014, Airstrikes to Assist Iraq, Protect Civilians, Provide Security for U.S. Facilities and Personnel: notification informed Congress of airstrikes against ISIL forces to assist Iraqi security forces in retaking Mosul Dam in northern Iraq. September 1, 2014, Airstrikes to Assist Iraq, Humanitarian Assistance and Intervention: notification informed Congress of airstrikes near Amirli in northern Iraq targeting ISIL forces besieging the town and as part of a mission to provide humanitarian assistance. September 5, 2014, Increased Security Deployment: notification explained the deployment of 350 additional combat-equipped troops to provide security for diplomatic facilities and personnel in Baghdad. September 8, 2014, Airstrikes to Assist Iraq, Protect Civilians, Provide Security for U.S. Facilities and Personnel: notification of airstrikes "in the vicinity of the Haditha Dam in support of Iraqi forces in their efforts to retain control of and defend this critical infrastructure site from ISIL," stating that "[t]hese additional military operations will be limited in their scope and duration as necessary to address this threat and prevent endangerment of U.S. personnel and facilities and large numbers of Iraqi civilians."

In each of these notifications, President Obama cited no war declaration or legislative authorization for use of military force that authorized his actions, but instead relied on his constitutional authority under Article II as Commander in Chief and Chief Executive. Without such legislative authority, any engagement in hostilities could have been considered to trigger the 60-day withdrawal requirement under Section 5(b). Although there was no indication from the President, the deployments announced in the June 16, June 24, June 30, and September 5 WPR notifications could have been construed as falling under Section 4(a)(2) and/or (3) of the WPR; such interpretation would not have triggered the WPR withdrawal requirement. The airstrikes notifications of August 8, August 17, and September 1, 2014, seem more likely to concern activities considered hostilities under the WPR, and therefore could be considered Section 4(a)(1) notifications, triggering the 60-day withdrawal period, although again, neither the President nor Congress took any action to definitively characterize such actions as triggering the WPR withdrawal requirement.

President Obama's multiple notifications, some of which involved hostilities, raised questions about whether multiple WPR notifications for short-term, circumscribed military action in relation to the same enemy in the same conflict should be considered separately or be combined for purposes of the operation of the WPR withdrawal requirement. Analysts and Members of Congress struggled with how to determine whether the 60-day period was running, on what date it began, or whether it had reset each time one of the three discrete military operations had ceased. From the description in the airstrikes notifications, the Mount Sinjar, Mosul Dam, and Amirli operations involved operations by U.S. Armed Forces conducting airstrikes that lasted only a few days at most, such forces engaged in airstrikes likely entered, fought, and withdrew from Iraqi airspace in a matter of hours, and the troops that remained in Iraq after the airstrikes were apparently not engaged in hostilities or present where hostilities were imminent. In addition, the Obama Administration has been careful to state that the first airstrikes were solely to halt the advance of ISIL on Erbil and break the siege of Mount Sinjar, both of which were accomplished at the end of operations, that the second airstrikes were to help with the recapture of Mosul Dam, which was also completed, and that the third airstrikes were solely to protect ISIL-besieged Iraqi citizens in Amirli, and that objective also seemed to have been met, each within a matter of days.

Some analysts raised the question whether the President's frequent notifications, each explaining a discrete operation that would last only a few days, were intended simply to ensure that Congress was kept informed in detail about ongoing U.S. military action in Iraq or, alternatively, whether they were intended to have some consequence for assessing when and whether the WPR's 60-day deadline for termination of hostilities begins and ends—that is to say, that each of the particular actions reported constitutes a separate military action that is subject to its own 60-day deadline for termination. Because the operations were short in duration, considering each operation to operate under its own 60-day period, despite seemingly being part of a larger campaign against one enemy, would arguably undercut the WPR's goal of ensuring that U.S. forces were not engaged in hostilities against an enemy force for a sustained period of time without congressional authorization.

Notifications of discrete, time-limited deployments and hostilities have occurred in the past. Since Congress enacted the War Powers Resolution, Presidents have made Section 4 notifications that refer to military deployments and operations, including the use of military force, that are relatively small in scope and duration, involving individual strikes. These limited WPR notifications, however, often involve either planned strikes against foreign targets that can be regarded as isolated and not part of a larger, connected military campaign against an enemy, or address one-time defensive military action against armed attack.

Presidential Reliance on Prior Existing Authorizations to Meet War Powers Resolution Requirements

After relying on Article II authority as Commander in Chief and Chief Executive in his first seven WPR notifications concerning military action against the Islamic State, President Obama changed course and began relying on existing authorizations for the continuing and expanding military campaign. Obama Administration officials and the President's September 2014 notifications to Congress for airstrikes and other actions in Iraq and Syria stated that two enacted authorizations for use of military force (AUMFs) currently in force, the Authorization for Use of Military Force (2001 AUMF; P.L. 107-40 ), and the Authorization for Use of Military Force Against Iraq Resolution of 2002 (2002 AUMF; P.L. 107-243 ), provide authorization for certain U.S. military strikes against the Islamic State in Iraq and Syria, as well as the Khorasan Group of Al Qaeda in Syria. As it regarded the requirements of the WPR, President Obama by citing 2001 and 2002 AUMF authority provided a legislative basis for his decision to engage U.S. Armed Forces in hostilities against the Islamic State and other groups, which would meet the WPR's notification requirements, and prevent application of Section 5(b)'s 60-day withdrawal requirement and the WPR's provisions for consideration of legislative proposals to approve or disapprove of his actions. Trump Administration officials have also argued that existing legislative authority covers U.S. military operations against the Islamic State in Iraq, Syria, and elsewhere.

Congress enacted the 2001 AUMF in response to the September 11, 2001, terrorist attacks, authorizing the President to use military force against "those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons...." The executive branch has since relied on the 2001 AUMF to fight Al Qaeda and the Taliban in Afghanistan, and has stated that the 2001 AUMF authorizes limited, targeted U.S. military strikes against Al Qaeda and associated forces that have been carried out in other countries, including Pakistan, Yemen, Somalia, and Libya. President Obama's reliance on 2001 AUMF authority to undertake a large-scale, long-term military campaign outside Afghanistan to fight the Islamic State represented to some observers an expansion of the interpretation of 2001 AUMF authority. The Obama Administration stated that the Islamic State can be targeted under the 2001 AUMF because its predecessor organization, Al Qaeda in Iraq, communicated and coordinated with Al Qaeda; the Islamic State currently has ties with Al Qaeda fighter and operatives; the Islamic State employs tactics similar to Al Qaeda; and the Islamic State, with its intentions of creating a new Islamic caliphate, is the "true inheritor of Osama bin Laden's legacy."

The 2002 AUMF authorizes the President to use U.S. Armed Forces to enforce relevant United Nations Security Council resolutions and to "defend the national security of the United States against the continuing threat posed by Iraq...." Although the 2002 AUMF has no sunset provision and Congress has not repealed it, one view is that after the establishment of a new Iraqi government, the restoration of full Iraqi sovereignty, and the U.S. withdrawal from Iraq, all completed by the end of 2011, the 2002 AUMF no longer has force. During the Obama Administration, executive branch officials voiced support for repealing the 2002 AUMF, reflecting the belief that it is no longer needed. Conversely, another view asserts that, although its preamble focuses on the Saddam Hussein regime and its WMD programs, the 2002 AUMF's authorization language is broad, referring only to a "continuing threat" from Iraq, and that the 2002 AUMF could provide authority to defend against threats to Iraq as well as threats posed by Iraq. Indeed, 2002 AUMF authority was the basis for the U.S. military presence in Iraq from the fall of Saddam Hussein and completion of the WMD search to its 2011 withdrawal, a span of over eight years, a period that could be characterized as dealing with threats to Iraq rather than threats from Iraq. The IS threat in Iraq could therefore be seen as breathing new life into 2002 AUMF authority. In addition, former supporters of Saddam Hussein reportedly provide support to the Islamic State, possibly forming a link between the original aims of the 2002 AUMF and any future actions taken against the Islamic State.

Congressional Action Related to War Powers Resolution Requirements

A number of legislative proposals have been introduced responding to presidential decisions to deploy U.S. Armed Forces and order the use of military force against the Islamic State and other groups. Some Members of Congress have proposed legislation restricting military action against the Islamic State under the 2001 and 2002 AUMFs, repealing these authorizations, and authorizing military force against the Islamic State in a new standalone AUMF. Proposals related to the WPR and its operation generally have been introduced during this period as well, possibly spurred by current U.S. use of military force against the Islamic State.

On June 19, 2014, three days after President Obama's first WPR notification concerning new deployments to Iraq, Congress considered two amendments to a Department of Defense appropriations bill ( H.R. 4870 , 113 th Congress), the first of which prohibiting the use of funds appropriated to the department pursuant to the 2002 AUMF, and the second prohibiting use of such funds under the 2001 AUMF after December 31, 2014. Both amendments were defeated by roll call vote.

Some Members of Congress also proposed legislation to require the President to either withdraw troops from Iraq pursuant to the procedures of the WPR or seek a new authorization for use of military force. A concurrent resolution ( H.Con.Res. 105 , 113th Congress) was introduced in the House of Representatives on July 11, 2014, requiring withdrawal from Iraq.

Section 1. Removal of United States Armed F orces from I raq.

Pursuant to section 5(c) of the War Powers Resolution (50 U.S.C. 1544(c)), Congress directs the President to remove United States Armed Forces, other than Armed Forces required to protect United States diplomatic facilities and personnel, from Iraq—

(1) by no later than the end of the period of 30 days beginning on the day on which this concurrent resolution is adopted; or

(2) if the President determines that it is not safe to remove such United States Armed Forces before the end of that period, by no later than December 31, 2014, or such earlier date as the President determines that the Armed Forces can safely be removed.

H.Con.Res. 105 was later amended to remove the direction to withdraw U.S. Armed Forces, replacing it with language stating that the "President shall not deploy or maintain United States Armed Forces in a sustained combat role in Iraq without specific statutory authorization for such use enacted after the date of the adoption of this concurrent resolution," and that nothing in the concurrent resolution supersedes the requirements of the WPR. This version of H.Con.Res. 105 passed the House by a vote of 370-40 on July 25, 2014. It was received in the Senate on July 28, 2014 and referred to the Senate Committee on Foreign Relations; no further action was taken.

After President Obama ordered airstrikes against IS forces in Iraq in August 2014, debate in Congress for the most part turned toward crafting a new authorization for use of military force against the Islamic State (IS AUMF), which would meet the requirements for continued military action after 60 days, rather than proposals prohibiting the use of funds for military operations or requiring an end to hostilities and withdrawal of U.S. Armed Forces from Iraq. Beginning in September 2014, several proposed IS AUMFs were introduced, many with provisions intended to define and circumscribe U.S. military engagement, likely a reaction to a perceived over-expansive interpretation and application of the 2001 AUMF by the executive branch since its initial enactment. Provisions in these proposals that would have restricted or limited Congress's overall grant of authority included

limiting the type of military action or military unit to be utilized, including broad prohibitions on the use of U.S. ground forces; limiting the geographic area where military action was authorized; limiting the lawful targets of military force, including limitations on targeting "associated forces" of the Islamic State; and terminating the authority automatically after a specific time period, from 120 days to three years after enactment.

One IS AUMF proposal, S.J.Res. 47 (113 th Congress), was debated, amended, and reported favorably to the full Senate by the Committee on Foreign Relations. After the resolution was reported to the Senate, no further action was taken in the 113 th Congress.

On February 11, 2015, President Obama provided Congress with his draft proposal for a new IS AUMF, The proposal would have authorized the use of U.S. Armed Forces that he deems "necessary and appropriate" against the Islamic State and associated persons or forces, meaning "individuals and organizations fighting for, on behalf of, or alongside ISIL or any closely-related successor entity in hostilities against the United States or its coalition partners." The authorization does not include authority for the use of U.S. Armed Forces for "enduring offensive ground combat operations." The proposal's authorization would terminate three years after enactment. The President would be required to report to Congress at least every six months on actions taken under the proposed IS AUMF, matching the timing of the reporting requirement in Section 4(c) of the WPR.

Since President Obama's proposal, Members of Congress have continued to introduce new IS AUMFs. Many of these proposals, however, have not included provisions limiting the authority provided to the President to use military force against the Islamic State as several previous proposals had. Some of the proposals do contain a three-year sunset provision for such authority, however. Conversely, a few legislative proposals have been introduced to limit the President's use of military force against the Islamic State. H.Con.Res. 55 (114 th Congress), directing the President, pursuant to Section 5(c) of the War Powers Resolution, to remove U.S. Armed Forces deployed after August 7, 2014, in Iraq and Syria, was similar to the concurrent resolution from the 113 th Congress discussed above. It failed passage in the House by a vote of 139-288 on June 17, 2015. After the anti-IS strikes the United States conducted in Libya, an amendment was offered in the 114 th Congress to the House version of the Department of Defense Appropriations Act, 2017 ( H.Amdt. 1213 to H.R. 5293 , 114 th Congress), prohibiting the use of funds to engage in hostilities in Libya in contravention of the War Powers Resolution. The amendment failed passage by voice vote on June 16, 2016. Provisions in the House version of the Defense appropriations bill in the 115 th Congress (Sections 8115 and 9019 of H.R. 1301 , 115 th Congress) would prohibit the use of appropriated funds for deployments of U.S. Armed Forces in contravention of the consultation and reporting requirements of Sections 3 and 4 of the War Powers Resolution.

In addition, during the nearly three years since the U.S. military campaign against the Islamic State began, a number of proposals to repeal or sunset the 2001 and 2002 AUMFs have been introduced, both as part of IS AUMF and war declaration proposals as well as contained in standalone legislative vehicles. Proposed repeals were introduced both before and after President Obama announced his reliance on 2001 and 2002 AUMF authority for his decision to order a wider military campaign against IS and other forces in September 2014, and have continued into the first session of the 115 th Congress.

Niger: Hostilities Involving U.S. Forces Operating Under Title 10 Authorities

An incident involving casualties among U.S. Armed Forces deployed to provide nonlethal assistance under Title 10, U.S. Code authorities, raised the question of whether previous presidential reporting of a combat-equipped deployment is sufficient when hostilities break out involving such deployed forces, and whether the exercise of Title 10 authorities to train and assist foreign militaries might necessarily involve authorities for the use of military force in some cases. On October 4, 2017, four U.S. soldiers were killed and two were wounded when they and their Nigerien partners were ambushed in western Niger while on a reconnaissance patrol as part of overall U.S. counterterrorism operations in Niger and the Sahel region generally. The Department of Defense (DOD) later identified those responsible for the ambush as members of a group affiliated with the Islamic State, the Islamic State in the Greater Sahel (ISGS). A DOD investigation later revealed that the actions of U.S. forces involved in the patrol had improperly exposed the troops to potential attack and harm, outside the mission approved under applicable Title 10 training and assistance authority. The Trump Administration later reported another ISGS attack on U.S. and Nigerien troops on December 6, 2017.

Presidential reporting to Congress consistent with the War Powers Resolution with regard to U.S. Armed Forces operating in Niger began several years before the October 2017 ambush. President Obama, on February 22, 2013, notified Congress of the deployment of U.S. Armed Forces to that country. The notification stated,

This deployment will provide support for intelligence collection and will also facilitate intelligence sharing with French forces conducting operations in Mali, and with other partners in the region…. The recently deployed forces have deployed with weapons for the purpose of providing their own force protection and security.

Providing an explanation of applicable constitutional and/or legislative authority, President Obama stated that he had directed the deployment "pursuant to my constitutional authority to conduct U.S. foreign relations and as Commander in Chief and Chief Executive." Subsequent notifications updating Congress on the status of U.S. Armed Forces in Niger have been included regularly in the six-month periodic reports under the War Powers Resolution, reflecting an increase of total numbers of troops from approximately 40 in early 2013 to approximately 800 as of the June 2018 notification. The notifications referenced only activities for "support for intelligence collection [and] intelligence sharing with French forces in Mali, and with other forces in the region" until the June 2017 reporting, where it described U.S. forces in Niger and elsewhere in the Sahel region as "provid[ing] a wide variety of support to African partners conducting counterterrorism operations in the region," seemingly encompassing a wider possible range of CT operations for U.S. troops.

Some Members of Congress expressed surprise after the deaths of U.S. troops in Niger, not only regarding the circumstances of the ambush but also the overall mission and activities of U.S. Armed Forces in Niger overall. Despite certain presidential and other DOD reporting on U.S. military operations in Niger and the Lake Chad Basin and Sahel region in general, there was still a belief among some Members that Congress had not been adequately informed of these operations, especially as their scope and purpose had seemingly expanded from 2013 to 2017. U.S. Armed Forces deployed while equipped for combat were operating in Niger and many other countries in Africa and elsewhere under Title 10 authority to assist foreign militaries: it seemed to some that such forces might at any time be engaged in hostilities against terrorist groups or other enemies alongside foreign military partners, just as had occurred in Niger. In such circumstances, Congress would be notified of a Title 10 deployment, but would have little chance to authorize or otherwise offer input concerning a decision to use military force or place U.S. troops in a situation where such use of force might be necessary.

A question in the context of the Niger situation is whether the presidential reporting requirements in the War Powers Resolution might have been utilized to provide more timely information to Congress. As described earlier in this report, Section 4(a) of the War Powers Resolution requires the President, absent a relevant declaration of war from Congress, to notify Congress within 48 hours after introducing U.S. Armed Forces "into hostilities or situations where imminent involvement in hostilities is clearly indicated by the circumstances" (paragraph (a)(1)), or, short of hostilities, introducing U.S. combat-equipped armed forces into a foreign country (paragraphs (a)(2) or (3)). Although the executive branch maintains that hostilities occur only with exchanges of fire between U.S. and enemy forces, the legislative history of the War Powers Resolution refers to hostilities as also including "a state of confrontation in which no shots have been fired but where there is a clear and present danger of armed conflict," and that imminent hostilities means "a situation in which there is a clear potential either for such a state of confrontation or for actual armed conflict." A original deployment absent imminent or active hostilities reported under Section 4(a)(2) or (3) might later be expected to generate a new notification under Section 4(a)(1), if hostilities were to commence.

In the case of the deployments to Niger beginning in 2013, presidential reporting first referred only to intelligence support in describing the U.S. mission, but later described broader U.S. military operations to include conducting patrols with Nigerien forces. With U.S. forces placed in the same "state of confrontation" and possible active hostilities with terrorist and other enemy groups as their Nigerien partners, a presidential report under Section 4(a)(1) of the War Powers Resolution, requiring reporting within 48 hours, might have been expected. Similarly, when the extended firefight between U.S. and Nigerien forces and ISGS elements occurred October 4, 2017, resulting in U.S. dead and wounded, a Section 4(a)(1) might also have been expected within 48 hours of the exchange of fire, but no such notification was made. The President did, however, include information concerning the ambush in Niger in his December 2017 six-month periodic reporting consistent with Section 4(c) of the War Powers Resolution.

As the Niger operation represented a use of military force, however limited, in a new foreign country, some observers and Members of Congress raised questions about the U.S. military activities leading up to the October 2017 ambush and the possibility that further hostilities might occur in Niger and other foreign countries where U.S. Armed Forces were engaged in close cooperation with partner forces facing active enemy groups. Of particular interest was whether the use of military force in Niger by U.S. troops would be considered authorized by the Authorization for Use of Military Force (2001 AUMF; P.L. 107-40 ; 50 U.S.C. §1541 note), which had been applied to the use of military force against Al Qaeda, the Taliban, the Islamic State, and several "associated forces" in Afghanistan, Iraq, Libya, Somalia, Syria, and Yemen.

Trump Administration officials, including Secretary of Defense James Mattis, initially asserted that U.S. troops were operating under Title 10 training and assistance authorities, and were not acting under 2001 AUMF authority. Later Administration statements seemed to call this initial assertion into question, however. DOD identified the attackers in the two Niger incidents as elements of the Islamic State, a group the executive branch had already determined was a targetable entity under the 2001 AUMF. These IS elements were eventually referred to as an IS-associated force known as ISGS, or ISIS-GS in DOD documents. A May 2018 DOD report on the October 2017 ambush stated that U.S. Special Operations Forces in Niger "have the authority to conduct CT operations with partner Nigerien forces," including operations "targeting … key member[s] of ISIS-GS," seemingly outside nonlethal Title 10 authorities. In a reversal of initial statements, in March 2018 the Administration explained that the 2001 AUMF did in fact apply to U.S. use of military force in Niger:

On October 4, 2017 and December 6, 2017, those U.S. forces and their Nigerien partner forces were attacked by forces assessed to be elements of ISIS, a group within the scope of the 2001 AUMF, and responded with force in self-defense. The Administration has concluded that this use of force was also conducted pursuant to the 2001 AUMF.

Despite finding that 2001 AUMF authority applies to the use of military force in Niger, DOD reportedly has also explained that U.S. use of military force in Niger and in other foreign countries where U.S. Armed Forces are operating under Title 10 is authorized under the "collective self-defense supplemental rule of engagement," which permits U.S. Armed Forces working alongside foreign partner forces to use military force against enemies who attack either U.S. forces or partner forces, including enemies not authorized to be targeted under "by the 2001 AUMF or other congressional authorizations for the use of force." While utilization of self-defense and collective self-defense concepts would seem to be necessary in individual instances where U.S. forces conducting training and other assistance operations and their foreign partners come under attack, some argue such concepts might be applied to permit ongoing uses of military force where no congressional authorization exists. From the standpoint of the operation of the War Powers Resolution, this might be expected to produce more situations in which presidential notifications under Section 4(a)(2) or (3), reporting combat-equipped deployments but no hostilities, are used to satisfy presidential reporting requirements without additional reporting of hostilities under Section 4(a)(1), as initially occurred in the Niger situation. This might make it more difficult for Congress to engage in a timely manner as to the details of individual instances of the introduction of U.S. Armed Forces into hostilities, their estimated scope and duration, and the proper constitutional and legislative authority for such uses of military force.

Yemen: "Hostilities" and Support of Foreign Military Action

Responding to the outbreak of civil war in Yemen and the Ansar Allah/Houthi movement's ouster of the Yemeni government in 2015, Saudi Arabia in the intervening years has led a coalition of countries in a military campaign to reverse gains made by the Houthi and restore Yemen's government to power. The air forces of the Kingdom of Saudi Arabia (KSA) and the United Arab Emirates (UAE) have continued to conduct airstrikes against Houthi targets in Yemen during this time. Houthi forces have conducted cross border missile and mortar attacks against Saudi Arabia and the UAE, with some apparent support from Iran. U.S. Armed Forces have provided discrete support to some Saudi and Emirati military operations against Houthi forces, with current operations reported to be specifically focused on Houthi missile force targets.

Operating pursuant to bilateral agreements, the United States has provided "the KSA-led coalition defense articles and services, including air-to-air refueling; certain intelligence support; and military advice, including advice regarding compliance with the law of armed conflict and best practices for reducing the risk of civilian casualties," according to the Department of Defense. In June 2018, President Trump notified Congress, consistent with the War Powers Resolution, that "United States Armed Forces, in a non-combat role, have continued to provide military advice and limited information, logistics, and other support to regional forces combatting the Houthi insurgency in Yemen. United States forces are present in Saudi Arabia for this purpose." On November 9, 2018, the United States and Saudi Arabia announced that U.S. Armed Forces would cease air-to-air refueling of Saudi and Emirati aircraft engaged in the counter-Houthi campaign in Yemen. U.S. refueling missions had resupplied some Saudi and Emirati aircraft since 2015 pursuant to bilateral acquisition and cross-servicing agreements.

In a bid to counter weapons proliferation to the Houthi and limit opportunities for Houthi exploitation of commerce, Saudi forces have imposed strict limits on the transit of vessels via air and sea to Yemen since 2015. These limits have been moderated to some extent by coalition coordination with a U.N. Verification and Inspection Mechanism (UNVIM) but nevertheless have contributed to shortages of food, fuel, and commercial products across the country. Along with ongoing conflict and disruption of infrastructure, the coalition-imposed limits have become a key factor in what the United Nations and various humanitarian and human rights organizations describe as a humanitarian emergency in Yemen. As of November 2018, U.N. officials have warned that as many as 14 million Yemenis are at risk of famine because of the ongoing conflict and related restrictions and disruptions of shipments of food, fuel, and goods.

Military operations by the KSA-led coalition, especially some air-to-ground strikes by Saudi and other coalition aircraft, also have been identified as having caused high levels of civilian casualties and destruction of civilian infrastructure. KSA-led coalition officials state they are committed to protecting civilians, improving their military operations, and supporting humanitarian access and aid delivery programs. Saudi Arabia and the UAE continue to pledge considerable financial support to relief efforts while, until recently, carrying forward military campaigns aimed at evicting Houthi fighters from the Red Sea port of Hodeidah and the capital Sanaa, and targeting Houthi leaders and forces involved in cross-border attacks. In December 2018, the parties to the conflict met in Stockholm, Sweden, for talks on the conflict, ultimately ending in a ceasefire agreement to be implemented with assistance from the United Nations. In February 2019, it was announced that the Yemeni government and the Houthis had agreed to execute a significant part of the Stockholm agreement, withdrawing troops from Hodeidah. But subsequent reports that fighting has intensified in the north of Yemen, among other escalations, continue to cast doubt on the overall durability of the ceasefire and future prospects for an end to the conflict.

Some Members of Congress have voiced concerns about the overall situation in Yemen, the actions of the Saudi military in its prosecution of its conflict with the Houthis, and the involvement of the U.S. military to date in the KSA-led campaign. Some Members have also argued that current U.S. operations to support the KSA-led campaign in Yemen represent a use of U.S. Armed Forces requiring a new, specific authorization from Congress.

WPR-Related Congressional Action to Disapprove U.S. Military Involvement

Driven by a range of Yemen-related concerns, Representative Ro Khanna and three co-sponsors on September 27, 2017, introduced a concurrent resolution ( H.Con.Res. 81 ) "pursuant to section 5(c) of the War Powers Resolution" directing the President "to remove United States Armed Forces from hostilities in the Republic of Yemen, except United States Armed Forces engaged in operations directed at Al Qaeda in the Arabian Peninsula or associated forces, by not later than the date that is 30 days after the date of the adoption" of the resolution. In the preamble, the resolution asserts that U.S. Armed Forces "have been involved in hostilities between Saudi-led forces and the Houthi-Saleh alliance, including" airstrike targeting assistance and mid-air refueling of Saudi and UAE aircraft. The resolution further states that "[n]o authorization for the use of United States Armed Forces with respect to the conflict between Saudi-led forces and the Houthi-Saleh alliance in Yemen has been enacted, and no provision of law authorizes the provision of midair refueling services to warplanes of Saudi Arabia or the United Arab Emirates that are engaged in such conflict."

H.Con.Res. 81 was treated as a privileged resolution entitled to expedited consideration under Section 7 of the WPR. On October 11, the House adopted by unanimous consent a motion to consider the resolution under Section 7 expedited procedures, but delayed the operation of such procedures until not earlier than November 2, 2017.

Before expedited procedures became applicable to H.Con.Res. 81 , proponents of the resolution, leaders of both parties in the House, and the House Foreign Affairs and Rules Committees, agreed to consider a separate simple resolution on the situation in Yemen, H.Res. 599, which was introduced by Representative Khanna on November 1, 2017. On the same day, the House adopted a motion stating that Section 7 of the WPR should not apply to H.Con.Res. 81 , and that it was in order to consider H.Res. 599 at any time, with one hour of debate on H.Res. 599 to take place before a vote of the full House. Like H.Con.Res. 81 , the language of H.Res. 599 also included the assertion, among other things, that Congress has not enacted an authorization to use military force against parties to the Yemeni civil war not otherwise subject to the 2001 or 2002 AUMFs, but did not require a withdrawal of U.S. Armed Forces from any hostilities related to the conflict in Yemen. After floor debate, the House voted 366-30 to adopt H.Res. 599 on November 13, 2017.

The Senate subsequently took up a similar proposal to H.Con.Res. 81 . On February 28, 2018, Senator Bernard Sanders and two co-sponsors introduced S.J.Res. 54, a joint resolution requiring the President to remove U.S. Armed Forces from hostilities "in or affecting" Yemen, except forces fighting Al Qaeda or its associated forces. Because it is a joint resolution directing a termination of hostilities, S.J.Res. 54 relied on the authority provided in Section 1013 of the Department of State Authorization Act, Fiscal Years 1984 and 1985 ("Section 1013"; 50 U.S.C. §1546a), rather than Section 5(c) of the WPR. Incorporating the expedited procedure in Section 601(b) of the International Security Assistance and Arms Export Control Act of 1976 ("Section 601(b)"; P.L. 94-329 ; 90 Stat. 765), Section 1013 authorizes a motion to discharge a joint resolution such as S.J.Res. 54 from the Foreign Relations Committee if the committee has not reported the resolution to the full Senate within 10 calendar days.

In accordance with this provision, on March 20, 2018, Senator Sanders made a motion to discharge S.J.Res. 54 from the committee. Senator Bob Corker, Chairman of the Foreign Relations Committee, arguing that the Foreign Relations Committee had committed to active oversight over the Yemen situation and had not yet been able to complete such oversight, moved to table the motion to discharge. After debate, the motion to table the motion to discharge S.J.Res. 54 was adopted by a vote of 55-44 on March 20, 2018.

On September 26, 2018, Representative Khanna and 26 cosponsors introduced H.Con.Res. 138 , another concurrent resolution to disapprove U.S. military activities with regard to Yemen and to require removal of U.S. Armed Forces from hostilities related to the KSA-led counter-Houthi campaign. The resolution is similar in its aims to H.Con.Res. 81 , but contains new language, including a specific reference to Section 8(c) of the WPR (50 U.S.C. §1547(c)):

(4) Section 8(c) of the War Powers Resolution (50 U.S.C. 1547(c)) defines the introduction of United States Armed Forces to include "the assignment of members of such armed forces to command, coordinate, participate in the movement of, or accompany the regular or irregular military forces of any foreign country or government when such military forces are engaged, or there exists an imminent threat that such forces will become engaged, in hostilities".

In addition, H.Con.Res. 138 , in its provision directing removal of U.S. Armed Forces, references military activities authorized pursuant to the Authorization for Use of Military Force (2001 AUMF; P.L. 107-40 ; 50 U.S.C. §1541 note), rather than describing counterterrorism operations against Al Qaeda in the Arabian Peninsula (AQAP) in Yemen, as does H.Con.Res. 81 . The executive branch has relied on 2001 AUMF authority to conduct its anti-AQAP operations in Yemen, but some Members of Congress have long disagreed with what they see as the executive branch's over-expansive interpretation of 2001 AUMF authority, including its application in Yemen.

On November 13, 2018, the House Rules Committee voted to submit a separate resolution to the full House that would, among other things, rescind the applicability of the expedited consideration privilege in Section 7 of the WPR (50 U.S.C. §1546) to H.Con.Res. 138 . The next day, November 14, the full House voted 201-187 to adopt this resolution, H.Res. 1142, thus effectively "deprivileging" H.Con.Res. 138 in the House. On November 29, 2018, Representative Khanna introduced H.Con.Res. 142 , containing identical language to H.Con.Res. 138 .

In the Senate, S.J.Res. 54 became the pending business of the chamber once again in the last week of November 2018, with Senator Sanders making a motion to discharge the Senate disapproval resolution from the Foreign Relations Committee and subject the resolution to debate in the full Senate under the Section 1013 provisions described above. On November 28, 2018, the Senate voted 63-37 in favor of the motion to discharge, clearing the way for debate on the measure in the Senate.

Consideration of S.J.Res. 54 in the Senate proceeded in December 2018 under Section 601(b) procedure. After the Senate's adoption of the motion to discharge S.J.Res. 54 from the Foreign Relations Committee, Section 601(b) states that a motion to consider the resolution in the Senate is in order and is privileged. Senator Sanders made such a motion to proceed to consideration on December 12, 2018, which the Senate adopted by a 60-39 vote. The Senate also agreed, by a vote of 96-3, to a point of order that any amendments offered under Section 1013 must be germane to the underlying subject of S.J.Res. 54, U.S. involvement in the conflict in Yemen. The Senate then proceeded to debate S.J.Res. 54 on December 12-13, 2018. The Senators who spoke on the floor raised a number of issues related both to the substance of the resolution, as well as the appropriateness of applying expedited consideration procedures under Section 1013 to a resolution in this particular instance.

Supporters of the resolution argued that U.S. military activities to support the KSA-led counter-Houthi campaign constituted involvement in a war amounting to "hostilities" under the War Powers Resolution and Section 1013, citing language in the War Powers Resolution that refers to U.S. forces engaging in activities to "command, coordinate, participate in the movement of, or accompany" foreign forces, and characterizing U.S. forces supporting the KSA-led coalition as co-belligerents in the Yemen war. Citing Congress's sole power to declare war under the Constitution, supporters stated that because Congress had not authorized U.S. involvement in the war in Yemen, U.S. involvement in the war was unconstitutional and therefore must end. Senators opposed to the resolution responded that U.S. activities to provide aircraft refueling, targeting assistance, and intelligence sharing to the KSA-led coalition did not amount to "hostilities" under Section 1013 or the War Powers Resolution, because U.S. Armed Forces were not involved in "direct military action" against Houthi forces, nor were they operating alongside coalition forces engaging in such direct action. Characterizing U.S. support operations as hostilities in this case, they argued, would set a precedent that would prevent the U.S. military from carrying out many of the support operations it conducts around the world, including in crisis situations, unless Congress specifically authorized such use of the military.

With regard to the resolution's substance and purpose, proponents argued that U.S. involvement in the KSA-led campaign against the Houthis was supporting actions that had led to a severe humanitarian crisis and large numbers of civilian casualties. They asserted that stopping military assistance to the KSA-led campaign and a shift to diplomatic and multilateral tools would better alleviate the suffering of the Yemeni population. Some senators also stressed the troubling actions of the Saudi regime generally on human rights issues, especially the Saudi government's actions in the killing of journalist Jamal Khashoggi, and stated that continued support for the Saudi regime for its war in Yemen was not appropriate. Other senators countered these arguments, stating that continued U.S. involvement would better ensure fewer civilian deaths and an improvement in the humanitarian situation in Yemen. They also argued that withdrawing support from the KSA-led campaign would weaken Saudi Arabia and strengthen Iran, which has supported the Houthis, in Yemen. Opponents also raised the possibility that U.S. interests and national security might be threatened by terminating U.S. support, including through an increased risk to terrorist attacks against the United States and U.S. forces in the Middle East by elements of terror groups operating in Yemen, such as AQAP.

After debate on the resolution, the Senate also debated and voted on six amendments to S.J.Res. 54 on December 13, 2018. The Senate agreed to amendments

to include "refueling of non-United States aircraft" participating in the Yemen conflict in the definition of "hostilities" for purposes of S.J.Res. 54; to ensure nothing in the resolution be interpreted to disrupt U.S. military operations and cooperation with Israel; and to require reporting on the risks involved with ceasing certain U.S. support to the KSA-led coalition with regard to the people of the United States and Saudi Arabia, regional humanitarian crises, and terrorist attacks against the United States.

The Senate did not adopt two amendments that would have limited the scope of application of the resolution's prohibitions by excluding military operations intended to reduce civilian casualties or to enable adherence to the international law of armed conflict, and operations to support strikes against Houthi targets outside Yemen.

Immediately after these votes, the Senate proceeded to vote on passage of S.J.Res. 54, as amended, and the resolution passed the Senate by a vote of 56-41. The resolution was received in the House on December 19, 2018, where no further action was taken before the end of the 115 th Congress. Because Section 1013 expedited consideration procedure applies only in the Senate, the resolution was not privileged in the House.

On January 30, 2019, Representative Khanna and 96 co-sponsors introduced H.J.Res. 37 , which again would direct "the removal of United States Armed Forces from hostilities in the Republic of Yemen that have not been authorized by Congress." The language in H.J.Res. 37 as introduced was identical to the amended version of S.J.Res. 54 that passed the Senate in the 115 th Congress. The resolution was referred to the House Foreign Affairs Committee, which on February 6, 2019, considered the resolution at a markup session after a hearing of the full committee regarding U.S. policy in the Arabian peninsula. During markup, opponents of the measure argued that U.S. support operations related to the counter-Houthi campaign in Yemen were not "hostilities," and that passage of H.J.Res. 37 would set a precedent under which any Member of Congress could force votes calling into question "all U.S. security cooperation agreements throughout the world." Those in favor of the measure stated that U.S. actions in Yemen in this specific case involved direct involvement in an armed conflict, and that "support for ongoing hostilities by a third power and ally … qualify" as involvement of U.S. Armed Forces in hostilities. The committee voted 25-17 to report H.J.Res. 37 to the full House and recommend its passage.

On February 11, 2019, the House Rules Committee reported on H.Res. 122, which provided for immediate consideration in the House of H.J.Res. 37 , with one hour for general debate and 10 minutes for two amendments deemed in order by the rule. A motion to recommit with or without instruction was also permitted. On February 13, 2019, the House adopted H.Res. 122 and proceeded to debate on the resolution. Supporters of the measure reiterated that U.S. military support for the KSA-led coalition was counter to American interests and values and that the actions of the coalition were creating a humanitarian crisis in Yemen. Opponents stated that the situation would not improve if the United States removed its support, and that such a decision would embolden Iran's involvement in the Yemen conflict and take pressure off elements of Al Qaeda and the Islamic State in Yemen. With regard to the provisions of the War Powers Resolution and Section 1013, Members continued to disagree on the definition of hostilities and the appropriate use of the expedited consideration procedures afforded to Congress in that legislation.

The House considered one amendment in order, which would have added language to ensure that nothing in the resolution would be construed to hinder U.S. forces and officials from collecting, analyzing, and sharing intelligence. The amendment was agreed to by a 252-177 rollcall vote. The House then considered a motion to recommit H.J.Res. 37 to the House Foreign Affairs Committee, with an instruction to report the resolution back to the House with an amendment to the findings section of the resolution. The amendment would have added language stating that it is in the "national security interest of the United States to combat anti-Semitism around the world," among other supporting statements. The motion to recommit with instruction was agreed to by a 424-0 vote. The House then proceeded to vote on H.J.Res. 37 , as amended, passing the resolution 248 to 177. On February 14, the House transmitted H.J.Res. 37 as adopted to the Senate, where it was referred to the Foreign Relations Committee.

H.J.Res. 37 is a joint resolution introduced with specific reference to Section 1013 expedited consideration procedure, and therefore could have been expected to receive expedited consideration once it passed the House and was received in the Senate. Its privileged status in the Senate, however, was eliminated on February 25, 2019, when the Senate Parliamentarian ruled that elements of the House-passed resolution were not germane to the subject of withdrawal of U.S. Armed Forces from hostilities in Yemen, and therefore the resolution could not be treated as privileged under Section 1013 procedure. At issue it seemed were the provisions on combating anti-Semitism added to the resolution in the motion to recommit that the House agreed to on February 13, 2019. After the decision of the Parliamentarian, Senators Sanders, Mike Lee, and Chris Murphy, co-authors of S.J.Res. 7, the companion measure in the Senate to H.J.Res. 37 , stated that they would take steps to ensure that their joint resolution, which does not contain the anti-Semitism language, receives consideration and a vote in the Senate under the Section 1013 privilege. The Senate is expected to take up S.J.Res. 7 in some fashion in March 2019.

What Constitutes U.S. "Hostilities" Related to Yemen

In the case of U.S. operations supporting the KSA-led counter-Houthi campaign, the executive branch and certain Members of Congress have disagreed over the meaning of "hostilities" as it relates to the application of the WPR provisions. The executive branch has maintained that "hostilities" for the purposes of the WPR means only "a situation in which units of U.S. armed forces are actively engaged in exchanges of fire with opposing units of hostile forces," something that it argues is not occurring in the context of the counter-Houthi operations. Congress's intent in using the term "hostilities," however, seems to evidence a definition that is wider in scope, to include diverse circumstances in which no exchanges of fire have yet occurred. Some indication of this intended wider meaning of hostilities and imminent hostilities is given in the House report on its War Powers bill:

The word hostilities was substituted for the phrase armed conflict during the subcommittee drafting process because it was considered to be somewhat broader in scope. In addition to a situation in which fighting actually has begun, hostilities also encompasses a state of confrontation in which no shots have been fired but where there is a clear and present danger of armed conflict. " Imminent hostilities " denotes a situation in which there is a clear potential either for such a state of confrontation or for actual armed conflict.

In this conception, a range of situations into which U.S. Armed Forces are deployed could be considered active or imminent hostilities subject to the reporting and termination requirements of the WPR, for example

U.S. Armed Forces actively exchanging fire with enemy forces; a standoff between U.S. and enemy forces poised to engage in armed conflict; or a circumstance where U.S. Armed Forces are equipped for combat in a foreign country where an opposing military might be expected to take an adversarial stance at some point in the near future against such U.S. Armed Forces.

In the context of U.S. operations related to the counter-Houthi campaign in Yemen, however, this conception does not necessarily answer whether U.S. Armed Forces acting in noncombat support roles in an armed conflict, or a "state of confrontation," involving foreign partner military forces, are properly considered engaged in active hostilities or where hostilities are imminent. According to the House report quoted above, hostilities encompass armed conflict, involving the exchange of fire between U.S. Armed Forces and enemy forces, or a state of confrontation with a clear and present danger of armed conflict. As the term is used in the WPR, "hostilities" might not, then, include a situation in which U.S. Armed Forces are serving only in a noncombat support role, and would not engage in exchanges of fire with enemy forces in the case of active armed combat, or operate under a clear and present danger of exchanging fire in the case of a state of confrontation. This is the argument the Trump Administration is currently making with regard to U.S. military operations connected to the KSA-led counter-Houthi campaign in Yemen.

This approach to defining hostilities, however, might be considered overly narrow. Under international law, all members of the armed forces of a party to an armed conflict are considered combatants with the right to participate in such armed conflict. To the extent the United States can be considered a party to an armed conflict in Yemen, all U.S. Armed Forces participating arguably would be engaged in such armed conflict and thus "hostilities," under the more expansive definition of the term set out in the House report language above.

Interpretive Provision Related to Activities of Foreign Military Forces

Proponents in Congress of the several pending Yemen disapproval resolutions in the 115 th Congress have also argued that U.S. support operations aiding the KSA-led campaign in Yemen link U.S. operations to ongoing offensive strikes by Saudi and Emirati forces, thus introducing U.S. Armed Forces into hostilities under the interpretive provisions of Section 8 of the WPR. Section 8(c) defines the introduction of armed forces to include activities of U.S. Armed Forces in connection with the operations of foreign military forces:

(c) For purposes of this joint resolution, the term "introduction of United States Armed Forces" includes the assignment of members of such armed forces to command, coordinate, participate in the movement of, or accompany the regular or irregular military forces of any foreign country or government when such military forces are engaged, or there exists an imminent threat that such forces will become engaged, in hostilities.

The conference report on the WPR explained that this was language modified from a Senate provision requiring specific statutory authorization for assigning members of the Armed Forces for such purposes. The report of the Senate Foreign Relations Committee on its bill said

The purpose of this provision is to prevent secret, unauthorized military support activities and to prevent a repetition of many of the most controversial and regrettable actions in Indochina. The ever deepening ground combat involvement of the United States in South Vietnam began with the assignment of U.S. "advisers" to accompany South Vietnamese units on combat patrols; and in Laos, secretly and without congressional authorization, U.S. "advisers" were deeply engaged in the war in northern Laos.

This interpretive provision could be confusing from the standpoint of determining whether an "introduction of U.S. armed forces" specifically into active or imminent hostilities under Section 4(a)(1) has occurred. Section 8(c) on the one hand seems to indicate some intention that if U.S. Armed Forces are operating alongside foreign military forces engaged in hostilities, those hostilities could be attributed to such U.S. Armed Forces as well, triggering a report under Section 4(a)(1) and possibly the termination provisions of Section 5.

Yet, while Section 8(c) refers to a situation where foreign military forces are actively engaged or will be engaged imminently in hostilities, when this occurs and U.S. Armed Forces are operating alongside such foreign forces, this seems to meet only the definition of an "introduction of United States Armed Forces" for purposes of Section 4(a) of the WPR, not the definition of "hostilities" or "introduction of United States Armed Forces into hostilities ." Under Section 4(a), there are situations in which an introduction does not involve hostilities: an introduction can also involve foreign deployments of combat-equipped troops absent any U.S. forces engaged in active or imminent hostilities.

Thus, it seems that Section 8(c) contemplates situations where "assignment of [U.S.] armed forces to command, coordinate, participate in the movement of, or accompany" foreign forces engaged in or about to engage in hostilities would not necessarily be considered an introduction of U.S. Armed Forces into such hostilities. In addition, the Senate Foreign Relations Committee report quoted above refers specifically to Section 8(c) preventing " secret , unauthorized military support activities," something a report under Section 4(a)(2) or (3) could accomplish by bringing an otherwise secret deployment to light, without a deployment being considered an "introduction into hostilities."

The executive branch has notified Congress of the activities of U.S. military personnel in support of Saudi-led coalition military operations in Yemen in letters to Congress consistent with the War Powers Resolution. In February 2018, Department of Defense counsel argued in a letter to Congress,

The limited military and intelligence support that the United States is providing to the KSA-led coalition does not involve any introduction of U.S. forces into hostilities for purposes of the War Powers Resolution or of section 1013 of the Department of State Authorization Act, Fiscal Years 1984 and 1985 (50 USC 1546a).

The Department specifically argued that since U.S. personnel providing support to the Saudi-led coalition were not then engaged themselves in exchanges of fire, they had not been introduced into hostilities or situations where hostilities were imminent. The Department further stated that U.S. forces did not then "currently command, coordinate, accompany, or participate in the movement of coalition forces in counter-Houthi operations," nor were they "accompanying the KSA-led coalition when its military forces are engaged, or an imminent threat exists that they will become engaged, in hostilities."

After four decades in existence, controversy continues over the War Powers Resolution and its effectiveness and appropriateness as a system for maintaining a congressional role in the use of armed forces in conflict. One view is that the War Powers Resolution is basically sound and does not need amendment. Those who hold this opinion believe it has brought about better communication between the two branches in times of crisis, and has given Congress a vehicle by which it can act when a majority of Members wish to do so. The Resolution served as a restraint on the use of armed forces by the President in some cases because of awareness that certain actions might invoke its provisions. For example, the threat of invoking the War Powers Resolution may have been helpful in getting U.S. forces out of Grenada, in keeping the number of military advisers in El Salvador limited to 55, and in prodding Congress to take a stand on authorizing the war against Iraq.

A contrary view is that the War Powers Resolution is an inappropriate instrument that restricts the President's effectiveness in foreign policy and should be repealed. Those with this perspective believe that the basic premise of the War Powers Resolution is wrong because in it, Congress attempts excessive control of the deployment of U.S. military forces, encroaching on the responsibility of the President. Supporters of repeal contend that the President needs more flexibility in the conduct of foreign policy and that the time limitation in the War Powers Resolution is unconstitutional and impractical. Some holding this view contend that Congress has always had the power, through appropriations and general lawmaking, to inquire into, support, limit, or prohibit specific uses of U.S. Armed Forces if there is majority support. The War Powers Resolution does not fundamentally change this equation, it is argued, but it complicates action, misleads military opponents, and diverts attention from key policy questions.

A third view is that the War Powers Resolution has not been adequate to accomplish its objectives and needs to be strengthened or reshaped. Proponents of this view assert that Presidents have continued to introduce U.S. Armed Forces into hostilities without consulting Congress and without congressional authorization. Presidents have cited Section 4(a)(1) on only one occasion—Mayaguez—and by the time the action was reported, it was virtually over.

Holders of this third view have proposed various types of amendments to the War Powers Resolution. These include returning to the version originally passed by the Senate, establishing a congressional consultation group, adding a cutoff of funds, and providing for judicial review. A general discussion of these categories of possible changes follows.

Return to Senate Version: Enumerating Exceptions for Emergency Use

In 1977, Senator Thomas Eagleton proposed that the War Powers Resolution return to the original language of the version passed by the Senate, and this proposal has been made several times since. This would require prior congressional authorization for the introduction of forces into conflict abroad without a declaration of war except to respond to or forestall an armed attack against the United States or its forces or to protect U.S. citizens while evacuating them. The amendment would eliminate the construction that the President has 60 to 90 days in which he can militarily act without authorization. Opponents fear the exceptions to forestall attacks or rescue American citizens abroad would serve as a blanket authorization and might be abused, yet might not allow the needed speed of action and provide adequate flexibility in other circumstances.

Another proposal is to shorten the time period that the President could maintain forces in hostile situations abroad without congressional authorization from 60 to 30 days, or eliminate it altogether. Some proponents of this amendment contend the current War Powers Resolution gives the President 60 to 90 days to do as he chooses and that this provides too much opportunity for mischief or irreversible action. The original Senate version provided that the use of armed forces in hostilities or imminent hostilities in any of the emergency situations could not be sustained beyond 30 days without specific congressional authorization, extendable by the President upon certification of necessity for safe disengagement. Opponents of this and related measures argue that they induce military opponents to adopt strategies to win given conflicts in Congress that they could not win in the field over time.

Replace Automatic Withdrawal Requirement

The War Powers Resolution has an automatic requirement for withdrawal of troops 60 days after the President submits a Section 4(a)(1) report. Some Members of Congress favor replacing this provision with expedited procedures for a joint resolution to authorize the action or require disengagement. One of the main executive branch objections to the War Powers Resolution has been that the withdrawal requirement could be triggered by congressional inaction, and that adversaries can simply wait out the 60 days. By providing for withdrawal by joint resolution, this amendment would also deal with the provision for withdrawal by concurrent resolution, under a cloud because of the Chadha decision. On the other hand, a joint resolution requiring disengagement could be vetoed by the President and thus would require a two-thirds majority vote in both Houses for enactment.

Some proposals call for prohibiting the obligation or expenditure of funds for any use of U.S. Armed Forces in violation of the War Powers Resolution or laws passed under it except for the purpose of removing troops. Congress could enforce this provision by refusing to appropriate further funds to continue the military action. This has always been the case, some contend, and would not work because Congress would remain reluctant to withhold financial support for U.S. Armed Forces once they were abroad.

Elimination of Action by Concurrent Resolution

Many proposed amendments eliminate Section 5(c) providing that U.S. forces engaged in hostilities abroad without congressional authorization are to be removed if Congress so directs by concurrent resolution, and Section 7 providing priority procedures for a concurrent resolution. Those who hold this view contend the concurrent resolution section is invalid because of the Chadha decision.

Several proposals call for new and more detailed priority procedures for joint resolutions introduced under the War Powers Resolution. These would apply to joint resolutions either authorizing a military action or calling for the withdrawal of forces, and to congressional action to sustain or override a presidential veto of the joint resolution.

Several proposed amendments have focused on improving consultation under the War Powers Resolution, particularly by establishing a specific consultation group in Congress for this purpose. Senators Byrd, Nunn, Warner, and Mitchell have proposed the President regularly consult with an initial group of 6 Members—the majority and minority leaders of both Chambers plus the Speaker of the House and President pro tempore of the Senate. Upon a request from a majority of this core group, the President is to consult with a permanent consultative group of 18 Members consisting of the leadership and the ranking and minority members of the Committees on Foreign Relations, Armed Services, and Intelligence. The permanent consultative group would also be able to determine that the President should have reported an introduction of forces and to introduce a joint resolution of authorization or withdrawal that would receive expedited procedures.

Other Members have favored a consultation group, but consider that amendment of the War Powers Resolution is not required for Congress to designate such a group. On October 28, 1993, House Foreign Affairs Chairman Lee Hamilton introduced H.R. 3405 to establish a Standing Consultative Group. Its purpose would be to facilitate improved interaction between the executive branch and Congress on the use of U.S. military forces abroad, including under the War Powers Resolution or United Nations auspices. Members of the Consultative Group would be appointed by the Speaker of the House and the Majority Leader of the Senate, after consultation with the minority leaders. The Group would include majority and minority representatives of the leadership and the committees on foreign policy, armed services, intelligence, and appropriations.

Another proposal would attempt to improve consultation by broadening the instances in which the President is required to consult. This proposal would cover all situations in which a President is required to report, rather than only circumstances that invoke the time limitation, as is now the case.

Proposals have been made that any Member of Congress may bring an action in the United States District Court for the District of Columbia for judgment and injunctive relief on the grounds that the President or the U.S. Armed Forces have not complied with any provision of the War Powers Resolution. The intent of this legislation is to give standing to Members to assert the interest of the House or Senate, but whether it would impel courts to exercise jurisdiction is uncertain. Most recent federal court decisions have rejected War Powers lawsuits by congressional litigants on the grounds they lacked standing to sue. Proposals have also called for the court not to decline to make a determination on the merits, on the grounds that the issue of compliance is a political question or otherwise nonjusticiable; to accord expedited consideration to the matter; and to prescribe judicial remedies including that the President submit a report or remove Armed Forces from a situation.

Other proposals would construct a Hostilities Act or Use of Force Act and repeal the War Powers Resolution. A possible objection to invoking the War Powers Resolution is reluctance to escalate international tension by implying that a situation is war. Some would see this as a step in the wrong direction; in the Korean and Vietnam conflicts, some contend, it was self-deceptive and ultimately impractical not to recognize hostilities of that magnitude as war and bring to bear the Constitutional provision giving Congress the power to declare war.

With the increase in United Nations actions since the end of the Cold War, the question has been raised whether the War Powers Resolution should be amended to facilitate or restrain the President from supplying forces for U.N. actions without congressional approval. Alternatively, the United Nations Participation Act might be amended, or new legislation enacted, to specify how the War Powers Resolution is to be applied, and whether the approval of Congress would be required only for an initial framework agreement on providing forces to the United Nations, or whether Congress would be required to approve an agreement to supply forces in specified situations, particularly for U.N. peacekeeping operations.

Appendix A. Instances Reported Under the War Powers Resolution

This appendix lists reports Presidents have made to Congress through early 2017 as the result of the War Powers Resolution. Each entry contains the President's reference to the War Powers Resolution. The reports generally cite the President's authority to conduct foreign relations and as Commander in Chief; each entry indicates any additional legislative authority a President cites for his action. Several of the reports listed for the period since 1991, in particular, are reports regarding ongoing operations previously reported by the President, rather than completely new instances of use of the U.S. military overseas.

(1) Danang, Vietnam . On April 4, 1975, President Ford reported the use of naval vessels, helicopters, and Marines to transport refugees from Danang and other seaports to safer areas in Vietnam. His report mentioned Section 4(a)(2) of the War Powers Resolution and authorization in the Foreign Assistance Act of 1961 for humanitarian assistance to refugees suffering from the hostilities in South Vietnam. Monroe Leigh, Legal Adviser to the Department of State, testified later that the President "advised the members of the Senate and House leadership that a severe emergency existed in the coastal communities of South Vietnam and that he was directing American naval transports and contract vessels to assist in the evacuation of refugees from coastal seaports."

(2) Cambodia . On April 12, 1975, President Ford reported the use of ground combat Marines, helicopters, and supporting tactical air elements to assist with the evacuation of U.S. nationals from Cambodia. The report took note of both Section 4 and Section 4(a)(2) of the War Powers Resolution. On April 3, 1975, the day the President authorized the Ambassador to evacuate the American staff, he directed that the leaders of the Senate and House be advised of the general plan of evacuation. On April 11, the day he ordered the final evacuation, President Ford again directed that congressional leaders be notified.

(3) Vietnam . On April 30, 1975, President Ford reported the use of helicopters, Marines, and fighter aircraft to aid in the evacuation of U.S. citizens and others from South Vietnam. The report took note of Section 4 of the War Powers Resolution. On April 10, the President had asked Congress to clarify its limitation on the use of forces in Vietnam to insure evacuation of U.S. citizens and to cover some Vietnamese nationals, but legislation to this effect was not completed. On April 28, the President directed that congressional leaders be notified that the final phase of the evacuation of Saigon would be carried out by military forces within the next few hours.

(4) Mayaguez . On May 15, 1975, President Ford reported that he had ordered U.S. military forces to rescue the crew of and retake the ship Mayaguez that had been seized by Cambodian naval patrol boats on May 12, that the ship had been retaken, and that the withdrawal of the forces had been undertaken. The report took note of Section 4(a)(1) of the War Powers Resolution. On May 13, Administration aides contacted 10 Members from the House and 11 Senators regarding the military measures directed by the President.

(5) Iran . On April 26, 1980, President Carter reported the use of six aircraft and eight helicopters in an unsuccessful attempt of April 24 to rescue the American hostages in Iran. The report was submitted "consistent with the reporting provision" of the War Powers Resolution. President Carter said the United States was acting in accordance with its right under Article 51 of the United Nations Charter to protect and rescue its citizens where the government of the territory in which they are located is unable or unwilling to protect them. The Administration did not inform congressional leaders of the plan on grounds that consultation could endanger the success of the mission.

(6) Sinai . The United States, Egypt, and Israel signed an executive agreement on August 3, 1981, outlining U.S. participation in a Multinational Force and Observers unit to function as a peacekeeping force in the Sinai after Israel withdrew its forces. In anticipation of this accord, on July 21, 1981, President Reagan requested congressional authorization for U.S. participation. Congress authorized President Reagan to deploy military personnel to the Sinai in the Multinational Force and Observers Participation Resolution, P.L. 97-132 , signed December 29, 1981. On March 19, 1982, President Reagan reported the deployment of military personnel and equipment to the Multinational Force and Observers in the Sinai. The President said the report was provided "consistent with Section 4(a)(2) of the War Powers Resolution" and cited the Multinational Force and Observers Participation Resolution.

(7) Lebanon . On August 24, 1982, President Reagan reported the dispatch of 800 Marines to serve in the multinational force to assist in the withdrawal of members of the Palestine Liberation force from Lebanon. The report was provided "consistent with" but did not cite any specific provision of the War Powers Resolution. President Reagan had begun discussions with congressional leaders on July 6, 1982, after the plan had been publicly announced, and after leaks in the Israeli press indicated that he had approved the plan on July 2.

(8) Lebanon . On September 29, 1982, President Reagan reported the deployment of 1,200 Marines to serve in a temporary multinational force to facilitate the restoration of Lebanese government sovereignty. He said the report was being submitted "consistent with the War Powers Resolution." On this second Multinational Force in Lebanon there was a considerable amount of negotiation between the executive branch and Congress, but most of it occurred after the decision to participate had been made and the Marines were in Lebanon.

(9) Chad . On August 8, 1983, President Reagan reported the deployment of two AWACS electronic surveillance planes and eight F-15 fighter planes and ground logistical support forces to Sudan to assist Chad and other friendly governments helping Chad against Libyan and rebel forces. He said the report was being submitted consistent with Section 4 of the War Powers Resolution. On August 23, 1983, a State Department spokesman announced that the planes were being withdrawn.

(10) Lebanon . On August 30, 1983, after the Marines participating in the Multinational Force in Lebanon were fired upon and two were killed, President Reagan submitted a report "consistent with Section 4 of the War Powers Resolution." In P.L. 98-119 , the Multinational Force in Lebanon Resolution, signed October 12, 1983, Congress determined Section 4(a) had become operative on August 29, 1983, and authorized the forces to remain for 18 months.

(11) Grenada . On October 25, 1983, President Reagan reported that U.S. Army and Marine personnel had begun landing in Grenada to join collective security forces of the Organization of Eastern Caribbean States in assisting in the restoration of law and order in Grenada and to facilitate the protection and evacuation of U.S. citizens. He submitted the report "consistent with the War Powers Resolution." President Reagan met with several congressional leaders at 8 p.m. on October 24. This was after the directive ordering the landing had been signed at 6 p.m., but before the actual invasion that began at 5:30 a.m., October 25.

(12) Libya . On March 26, 1986, President Reagan reported (without any mention of the War Powers Resolution) that, on March 24 and 25, U.S. forces conducting freedom of navigation exercises in the Gulf of Sidra had been attacked by Libyan missiles. In response, the United States fired missiles at Libyan vessels and at Sirte, the missile site.

(13) Libya . On April 16, 1986, President Reagan reported, "consistent with the War Powers Resolution," that on April 14 U.S. air and naval forces had conducted bombing strikes on terrorist facilities and military installations in Libya. President Reagan had invited approximately a dozen congressional leaders to the White House at about 4 p.m. on April 14 and discussed the situation until 6 p.m. He indicated that he had ordered the bombing raid and that the aircraft from the United Kingdom were on their way to Libya and would reach their targets about 7 p.m.

(14) Persian Gulf . On September 23, 1987, President Reagan reported that, on September 21, two U.S. helicopters had fired on an Iranian landing craft observed laying mines in the Gulf. The President said that while mindful of legislative-executive differences on the interpretation and constitutionality of certain provisions of the War Powers Resolution, he was reporting in a spirit of mutual cooperation.

(15) Persian Gulf . On October 10, 1987, President Reagan reported "consistent with the War Powers Resolution" that, on October 8, three U.S. helicopters were fired upon by small Iranian naval vessels and the helicopters returned fire and sank one of the vessels.

(16) Persian Gulf . On October 20, 1987, President Reagan reported an attack by an Iranian Silkworm missile against the U.S.-flag tanker Sea Isle City on October 15 and U.S. destruction, on October 19, of the Iranian Rashadat armed platform used to support attacks and mine-laying operations. The report was submitted "consistent with the War Powers Resolution."

(17) Persian Gulf . On April 19, 1988, President Reagan reported "consistent with the War Powers Resolution" that in response to the U.S.S. Samuel B. Roberts striking a mine on April 14, U.S. Armed Forces attacked and "neutralized" two Iranian oil platforms on April 18 and, after further Iranian attacks, damaged or sank Iranian vessels. The President called the actions "necessary and proportionate." Prior to this action, the President met with congressional leaders.

(18) Persian Gulf . On July 4, 1988, President Reagan reported that on July 3 the USS Vincennes and USS Elmer Montgomery fired upon approaching Iranian small craft, sinking two. Firing in self-defense at what it believed to be a hostile Iranian military aircraft, the Vincennes had shot down an Iranian civilian airliner. The President expressed deep regret. The report was submitted "consistent with the War Powers Resolution."

(19) Persian Gulf . On July 14, 1988, President Reagan reported that, on July 12, two U.S. helicopters, responding to a distress call from a Japanese-owned Panamanian tanker, were fired at by two small Iranian boats and returned the fire. The report was submitted "consistent with the War Powers Resolution."

(20) Philippines . On December 2, 1989, President George H. W. Bush submitted a report to congressional leaders "consistent with" the War Powers Resolution, describing assistance of combat air patrols to help the Aquino government in the Philippines restore order and to protect American lives. After the planes had taken off from Clark Air Base to provide air cover, Vice President Quayle and other officials informed congressional leaders. On December 7, House Foreign Affairs Committee Chairman Dante Fascell wrote President Bush expressing his concern for the lack of advance consultation. In reply, on February 10, 1990, National Security Adviser Brent Scowcroft wrote Chairman Fascell that the President was "committed to consultations with Congress prior to deployments of U.S. Forces into actual or imminent hostilities in all instances where such consultations are possible. In this instance, the nature of the rapidly evolving situation required an extremely rapid decision very late at night and consultation was simply not an option."

(21) Panama . On December 21, 1989, President George H. W. Bush reported "consistent with the War Powers Resolution" that he had ordered U.S. military forces to Panama to protect the lives of American citizens and bring General Noriega to justice. By February 13, 1990, all the invasion forces had been withdrawn. President Bush informed several congressional leaders of the approaching invasion of Panama at 6 p.m. on December 19, 1989. This was after the decision to take action was made, but before the operation actually began at 1:00 a.m., December 20.

(22) Liberia . On August 6, 1990, President George H. W. Bush reported to Congress that following discussions with congressional leaders, a reinforced rifle company had been sent to provide additional security to the U.S. Embassy in Monrovia and helicopter teams had evacuated U.S. citizens from Liberia. The report did not mention the War Powers Resolution or cite any authority.

(23) Iraq . On August 9, 1990, President George H. W. Bush reported to Congress "consistent with the War Powers Resolution" that he had ordered the forward deployment of substantial elements of the U.S. Armed Forces into the Persian Gulf region to help defend Saudi Arabia after the invasion of Kuwait by Iraq. The Bush Administration notified congressional leaders that it was deploying U.S. troops to Saudi Arabia on August 7, the date of the deployment. After the forces had been deployed, President Bush held several meetings with congressional leaders and members of relevant committees, and committees held hearings to discuss the situation.

(24) Iraq . On November 16, 1990, President George H. W. Bush reported, without mention of the War Powers Resolution but referring to the August 9 letter, the continued buildup to ensure "an adequate offensive military option." Just prior to adjournment, Senate Majority Leader Mitchell and Speaker Foley designated Members to form a consultation group, and the President held meetings with the group on some occasions, but he did not consult the members in advance on the major buildup of forces in the Persian Gulf area announced November 8.

(25) Iraq . On January 18, 1991, President George H. W. Bush reported to Congress "consistent with the War Powers Resolution" that he had directed U.S. Armed Forces to commence combat operations on January 16 against Iraqi forces and military targets in Iraq and Kuwait. On January 12, Congress had passed the Authorization for Use of Military Force against Iraq Resolution ( P.L. 102-1 ), which stated it was the specific statutory authorization required by the War Powers Resolution. P.L. 102-1 required the President to submit a report to the Congress at least once every 60 days on the status of efforts to obtain compliance by Iraq with the U.N. Security Council resolution, and Presidents submitted subsequent reports on military actions in Iraq "consistent with" P.L. 102-1 . An exception is report submitted June 28, 1993, described below.

(26) Somalia . On December 10, 1992, President George H. W. Bush reported "consistent with the War Powers Resolution" that U.S. Armed Forces had entered Somalia on December 8 in response to a humanitarian crisis and a U.N. Security Council Resolution determining that the situation constituted a threat to international peace. He included as authority applicable treaties and laws, and said he had also taken into account views expressed in H.Con.Res. 370 , S.Con.Res. 132 , and the Horn of Africa Recovery and Food Security Act, P.L. 102-274 . On December 4, the day the President ordered the forces deployed, he briefed a number of congressional leaders on the action.

(27) Bosnia . On April 13, 1993, President Clinton reported "consistent with Section 4 of the War Powers Resolution" that U.S. forces were participating in a NATO air action to enforce a U.N. ban on all unauthorized military flights over Bosnia-Hercegovina, pursuant to his authority as Commander in Chief. Later, on April 27, President Clinton consulted with about two dozen congressional leaders on potential further action.

(28) Somalia . On June 10, 1993, President Clinton reported that in response to attacks against U.N. forces in Somalia by a factional leader, the U.S. Quick Reaction Force in the area had participated in military action to quell the violence. He said the report was "consistent with the War Powers Resolution, in light of the passage of 6 months since President Bush's initial report...." He said the action was in accordance with applicable treaties and laws, and said the deployment was consistent with S.J.Res. 45 as adopted by the Senate and amended by the House. (The Senate did not act on the House amendment, so Congress did not take final action on S.J.Res. 45 .)

(29) Iraq . On June 28, 1993, President Clinton reported "consistent with the War Powers Resolution" that on June 26 U.S. naval forces had launched missiles against the Iraqi Intelligence Service's headquarters in Baghdad in response to an unsuccessful attempt to assassinate former President Bush in Kuwait in April 1993.

(30) Macedonia . On July 9, 1993, President Clinton reported "consistent with Section 4 of the War Powers Resolution" the deployment of approximately 350 U.S. Armed Forces to Macedonia to participate in the U.N. Protection Force to help maintain stability in the area of former Yugoslavia. He said the deployment was directed in accordance with Section 7 of the United Nations Participation Act.

(31) Bosnia . On October 13, 1993, President Clinton reported "consistent with the War Powers Resolution" that U.S. military forces continued to support enforcement of the U.N. no-fly zone in Bosnia, noting that more than 50 U.S. aircraft were now available for NATO efforts in this regard.

(32) Haiti . On October 20, 1993, President Clinton submitted a report "consistent with the War Powers Resolution" that U.S. ships had begun to enforce a U.N. embargo against Haiti.

(33) Macedonia . On January 8, 1994, President Clinton reported "consistent with the War Powers Resolution" that approximately 300 members of a reinforced company team (RCT) of the U.S. Army's 3 rd Infantry Division (Mechanized) had assumed a peacekeeping role in Macedonia as part of the United Nations Protection Force (UNPROFOR) on January 6, 1994.

(34) Bosnia . On February 17, 1994, President Clinton reported "consistent with the War Powers Resolution" that the United States had expanded its participation in United Nations and NATO efforts to reach a peaceful solution in former Yugoslavia and that 60 U.S. aircraft were available for participation in the authorized NATO missions.

(35) Bosnia . On March 1, 1994, President Clinton reported "consistent with" the War Powers Resolution that on February 28 U.S. planes patrolling the "no-fly zone" in former Yugoslavia under the North Atlantic Treaty Organization (NATO) shot down 4 Serbian Galeb planes.

(36) Bosnia . On April 12, 1994, President Clinton reported "consistent with" the War Powers Resolution that on April 10 and 11, U.S. warplanes under NATO command had fired against Bosnian Serb forces shelling the "safe" city of Gorazde.

(37) Rwanda . On April 12, 1994, President Clinton reported "consistent with" the War Powers Resolution that combat-equipped U.S. military forces had been deployed to Burundi to conduct possible noncombatant evacuation operations of U.S. citizens and other third-country nationals from Rwanda, where widespread fighting had broken out.

(38) Macedonia . On April 19, 1994, President Clinton reported "consistent with the War Powers Resolution" that the U.S. contingent in the former Yugoslav Republic of Macedonia had been augmented by a reinforced company of 200 personnel.

(39) Haiti . On April 20, 1994, President Clinton reported "consistent with the War Powers Resolution" that U.S. naval forces had continued enforcement in the waters around Haiti and that 712 vessels had been boarded.

(40) Bosnia . On August 22, 1994, President Clinton reported the use on August 5 of U.S. aircraft under NATO to attack Bosnian Serb heavy weapons in the Sarajevo heavy weapons exclusion zone upon request of the U.N. Protection Forces. He did not cite the War Powers Resolution but referred to the April 12 report that cited the War Powers Resolution.

(41) Haiti . On September 21, 1994, President Clinton reported "consistent with the War Powers Resolution" the deployment of 1,500 troops to Haiti to restore democracy in Haiti. The troop level was subsequently increased to 20,000.

(42) Bosnia . On November 22, 1994, President Clinton reported "consistent with the War Powers Resolution" the use of U.S. combat aircraft on November 21, 1994, under NATO to attack bases used by Serbs to attack the town of Bihac in Bosnia.

(43) Macedonia . On December 22, 1994, President Clinton reported "consistent with the War Powers Resolution" that the U.S. Army contingent in the former Yugoslav Republic of Macedonia continued its peacekeeping mission and that the current contingent would soon be replaced by about 500 soldiers from the 3 rd Battalion, 5 th Cavalry Regiment, 1 st Armored Division from Kirchgons, Germany.

All appropriate precautions have been taken to ensure the safety of U.S. military personnel during their deployment." The President took note in his report that Congress had previously "expressed support for increased, comprehensive U.S. efforts to help mitigate and eliminate the threat posed by the LRA to civilians and regional stability" through the passage of the Lord's Resistance Army Disarmament and Northern Uganda Recovery Act of 2009, P.L. 111-172 , enacted May 24, 2010.

In Libya, after April 4, 2011, the United States transferred responsibility for military operations there to NATO, and U.S. involvement "assumed a supporting role in the coalition's efforts." U.S. support in Libya was limited to "intelligence, logistical support, and search and rescue assistance." The U.S. military aircraft were also used to assist in the "suppression and destruction of air defenses in support of the no-fly zone" over Libya. After April 23, 2011, the United States supported the coalition effort in Libya through use of "unmanned aerial vehicles against a limited set of clearly defined targets" there. Except in the case of operations to "rescue the crew of a U.S. aircraft" on March 21, 2011, and deploying 16 U.S. military personnel to aid in re-establishing the U.S. Embassy in Tripoli in September 2011, "the U.S. deployed no ground forces to Libya." On October 27, 2011, the United Nations terminated the "no-fly zone" effective October 31, 2011. NATO terminated its mission during this same time. U.S. military operations continue in Kosovo, as part of the NATO-led Kosovo Force (KFOR). Presently the United States contributes approximately 800 U.S. military personnel to KFOR.

(134) Somalia . On January 26, 2012, the President submitted to Congress, "consistent with the War Powers Resolution," a report detailing a successful U.S. Special Operations Forces operation in Somalia of January 24, 2012, to rescue Ms. Jessica Buchanan, a U.S. citizen who had been kidnapped by a group linked to Somali pirates and financiers. This operation was undertaken "by a small number of joint combat-equipped U.S. forces" following receipt of reliable intelligence establishing her location in Somalia. A Danish national Poul Hagen Thisted, kidnapped with Ms. Buchanan, was also rescued with her.

(135) Anti-terrorist operations . On June 15, 2012, the President reported to Congress, "consistent with" the War Powers Resolution, a consolidated report regarding various deployments of U.S. Armed Forces equipped for combat. In the efforts in support of U.S. counterterrorism (CT) objectives against al-Qa'ida, the Taliban and, associated forces, he noted that U.S. forces were engaged in Afghanistan in the above effort were "approximately 90,000." With regard to other counter-terrorism operations, the President stated that the United States had deployed "U.S. combat-equipped forces to assist in enhancing the CT capabilities of our friends and allies including special operations and other forces for sensitive operations in various locations around the world." He noted that the "U.S. military has taken direct action in Somalia against members of al-Qa'ida, including those who are also members of al-Shabaab, who are engaged in efforts to carry out terrorist attacks against the United States and our interests." The President further stated that the U.S. military had been "working closely with the Yemini government to operationally and ultimately eliminate the terrorist threat posed by al-Qa-ida in the Arabian Peninsula (AQAP), the most active and dangerous affiliate of al-Qa'ida today." He added that these "joint efforts have resulted in direct action against a limited number of AQAP operatives and senior leaders in that country who posed a terrorist threat to the United States and our interests." The President noted that he would direct "additional measures against al-Qa'ida, the Taliban, and associated forces to protect U.S. citizens and interests." Further information on such matters is provided in a "classified annex to this report...." Other military operations reported by the President include the deployment of U.S. combat-equipped military personnel to Uganda "to serve as advisors to regional forces that are working to apprehend or remove Joseph Kony and other senior Lord's Resistance Army (LRA) leaders from the battlefield and to protect local populations." The total number of U.S. military personnel deployed for this mission is "approximately 90," and elements of these U.S. forces have been sent to "forward locations in the LRA-affected areas of the Republic of South Sudan, the Democratic Republic of the Congo, and the Central African Republic." These U.S. forces "will not engage LRA forces except in self-defense." The President also reported that presently the U.S. was contributing "approximately 817 military personnel" to the NATO-led Kosovo Force (KFOR) in Kosovo. He also reported that the U.S. remained prepared to engage in "maritime interception operations" intended to stop the "movement, arming, and financing of certain international terrorist groups," as well as stopping "proliferation by sea of weapons of mass destruction and related materials." Additional details about these efforts are included in "the classified annex" to this report.

(136) Libya/Yemen . On September 14, 2012, the President reported to Congress, "consistent with" the War Powers Resolution, that on September 12, 2012, he ordered deployed to Libya "a security force from the U.S. Africa Command" to "support the security of U.S. personnel in Libya." This action was taken in response to the attack on the U.S. "diplomatic post in Benghazi, Libya," that had killed four America citizens, including U.S. Ambassador John Christopher Stevens. The President added on September 13, 2012, that "an additional security force arrived in Yemen in response to security threats there." He further stated that "Although these security forces are equipped for combat, these movements have been undertaken solely for the purpose of protecting American citizens and property." These security forces will remain in Libya and in Yemen, he noted, "until the security situation becomes such that they are no longer needed."

JOINT RESOLUTION Concerning the war powers of Congress and the President.

Resolved by the Senate and House of Representatives of the United States of America in Congress assembled,

Section 1. This joint resolution may be cited as the "War Powers Resolution."

Section 2. (a) It is the purpose of this joint resolution to fulfill the intent of the framers of the Constitution of the United States and insure that the collective judgment of both the Congress and the President will apply to the introduction of United States Armed Forces into hostilities, or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, and to the continued use of such forces in hostilities or in such situations.

(b) Under article I, section 8, of the Constitution, it is specifically provided that the Congress shall have the power to make all laws necessary and proper for carrying into execution, not only its own powers but also all other powers vested by the Constitution in the Government of the United States, or in any department or officer thereof.

(c) The constitutional powers of the President as Commander in Chief to introduce United States Armed Forces into hostilities, or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, are exercised only pursuant to (1) a declaration of war, (2) specific statutory authorization, or (3) a national emergency created by attack upon the United States, its territories or possessions, or its armed forces.

Section 3. The President in every possible instance shall consult with Congress before introducing United States Armed Forces into hostilities or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, and after every such introduction shall consult regularly with the Congress until United States Armed Forces are no longer engaged in hostilities or have been removed from such situations.

Section 4. (a) In the absence of a declaration of war, in any case in which United States Armed Forces are introduced—

(1) into hostilities or into situations where imminent involvement in hostilities is clearly indicated by the circumstances;

(2) into the territory, airspace, or waters of a foreign nation, while equipped for combat, except for deployments which relate solely to supply, replacement, repair, or training of such forces; or

(3) in numbers which substantially enlarge United States Armed Forces equipped for combat already located in a foreign nation;

the President shall submit within 48 hours to the Speaker of the House of Representatives and to the President pro tempore of the Senate a report, in writing, setting forth—

(A) the circumstances necessitating the introduction of United States Armed Forces;

(B) the constitutional and legislative authority under which such introduction took place; and

(C) the estimated scope and duration of the hostilities or involvement.

(b) The President shall provide such other information as the Congress may request in the fulfillment of its constitutional responsibilities with respect to committing the Nation to war and to the use of United States Armed Forces abroad.

(c) Whenever United States Armed Forces are introduced into hostilities or into any situation described in subsection (a) of this section, the President shall, so long as such armed forces continue to be engaged in such hostilities or situation, report to the Congress periodically on the status of such hostilities or situation as well as on the scope and duration of such hostilities or situation, but in no event shall he report to the Congress less often than once every six months.

Section 5.

(b) Within sixty calendar days after a report is submitted or is required to be submitted pursuant to section 4(a)(1), whichever is earlier, the President shall terminate any use of United States Armed Forces with respect to which such report was submitted (or required to be submitted), unless the Congress (1) has declared war or has enacted a specific authorization for such use of United States Armed Forces, (2) has extended by law such sixty-day period, or (3) is physically unable to meet as a result of an armed attack upon the United States. Such sixty-day period shall be extended for not more than an additional thirty days if the President determines and certifies to the Congress in writing that unavoidable military necessity respecting the safety of United States Armed Forces requires the continued use of such armed forces in the course of bringing about a prompt removal of such forces.

(c) Notwithstanding subsection (b), at any time that United States Armed Forces are engaged in hostilities outside the territory of the United States, its possessions and territories without a declaration of war or specific statutory authorization, such forces shall be removed by the President if the Congress so directs by concurrent resolution.
