The legislative branch of the federal government consists of the Congress, which is divided into two chambers: the U.S. Senate and the U.S. House of Representatives. Each member of Congress is elected by the people of his or her state. The House of Representatives, with membership based on state populations, has 435 seats, while the Senate, with two members from each state, has 100 seats. Members of the House of Representatives are elected for two-year terms, and Senators are elected for six-year terms. Agencies that provide support services for the Congress are also part of the legislative branch.
