what kinds of treaties can the president make
Treaty Clause The body of law governing U.S. foreign policy recognizes three mechanisms by which the United States enters into binding international obligations. The term "treaty" is used in a more restricted legal sense than in international law. U.S. law distinguishes what it calls treaties from congressional-executive agreements and executive agreements.[1] All three classes are considered treaties under international law; they are distinct only from the perspective of internal United States law. Distinctions among the three concern their method of ratification: by two-thirds of the Senate, by normal legislative process, or by the President alone, respectively. The Treaty Clause empowers the President to make or enter into treaties with the "advice and consent" of two-thirds of the Senate. In contrast, normal legislation becomes law after approval by simple majorities in both the Senate and the House of Representatives and the signature of the President.
War Powers Resolution Because the Constitution limits the President's authority in the use of force without a declaration of war by Congress, there is controversy as to whether the provisions of the resolution are consistent with the Constitution. Presidents have therefore drafted reports to Congress required of the President to state that they are "consistent with" the War Powers Resolution rather than "pursuant to" so as to take into account the presidential position that the resolution is unconstitutional.
