United States Senate

The United States Senate is the upper chamber of the bicameral legislature of the federal government of the United States, and together with the House of Representatives makes up Congress. It has 100 members—two from each state—and its purpose is to represent states in national legislative matters. Each senator serves a six-year term. The Vice President of the United States serves as president pro tempore (temporary president) when necessary and presides over daily sessions; in their absence, a majority party leader usually fulfills this role.
