The Senate plays a unique role in U.S. international relations. The Constitution authorizes the president to make treaties, but the president must then submit them to the Senate for its approval by a two-thirds vote. The Senate Foreign Relations Committee is integral to this process. The committee also evaluates nominees to the State Department.
Treaties
Under Article II, section 2 of the Constitution, the Senate must advise and consent to ratification of treaties that have been negotiated and agreed to by the president.
The president has the power to nominate ambassadors and appointments are made with the advice and consent of the Senate. The
State Department
formulates and implements the president's foreign policy. Learn more about ambassadors, diplomatic history, and American embassies.
