Established by the Constitution as one chamber of the federal government’s legislative branch, the United States Senate is comprised of one hundred members—two senators from each of the 50 states—who serve six-year, overlapping terms. Senators, along with members of the House of Representatives, propose, author, and vote on federal legislation that touches upon all aspects of U.S. domestic and foreign policy. Senators provide advice and consent on executive nominations and treaties and conduct oversight of all branches of the federal government.
Administrations come and go, Houses assemble and disperse, Senators change, but the Senate is always there in the Capitol, and always organized, with an existence unbroken since 1789.
Senator Henry Cabot Lodge, “The Senate,” 1903
