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.
U.S. Congress in relation to the president and Supreme Court The Constitution entrusts certain powers to the Senate alone. The President may only nominate for appointment Cabinet officials, judges, and other high officers "by and with the advice and consent" of the Senate. The Senate confirms most presidential nominees, but rejections are not uncommon. Furthermore, treaties negotiated by the President must be ratified by a two-thirds majority vote in the Senate to take effect. As a result, presidential arm-twisting of senators can happen before a key vote; for example, President Obama's secretary of state, Hillary Clinton, urged her former senate colleagues to approve a nuclear arms treaty with Russia in 2010.[10] The House of Representatives has no formal role in either the ratification of treaties or the appointment of federal officials, other than filling vacancies in the office of Vice-President; a vote in each House is required to confirm a president's nomination for vice-president if a vacancy happens.[11]
