This is the section of the U.S. government that is responsible for executing laws. The executive branch consists of: the President, the Vice President, the Cabinet, all the executive departments, and several administrative agencies.
Congress is the legislative branch of the federal government. It consists of the House of Representatives and the Senate. The House has 435 voting members, each one representing a congressional district, and 5 non-voting members, 1 each from the District of Columbia, Guam, the Virgin Islands, American Samoa, and 1 resident commissioner. The Senate has 100 members, 2 from each of the 50 states. The consent of both chambers is required to pass any legislation. It might only become law by being signed by the President; if the President vetoes such legislation, however, both houses of Congress must then re-pass the legislation, but by a two-thirds majority of each.
The judicial branch of the U.S. government is made up of the court system, with the Supreme Court as the highest court whose members are appointed by the President and confirmed by the Senate.
