United States Senate

The United States Senate is the upper chamber of the United States Congress, which, along with the United States House of Representatives—the lower chamber—constitutes the legislature of the United States. The Senate chamber is located in the north wing of the Capitol Building in Washington, D.C.

The composition and powers of the Senate are established by Article One of the United States Constitution. The Senate is composed of senators, each of whom represents a single state in its entirety. Each state is equally represented by two senators who serve staggered terms of six years. There are currently 100 senators representing the 50 states. From 1789 to 1913, senators were appointed by legislatures of the states they represented. They are now elected by popular vote following the ratification of the Seventeenth Amendment in 1913.
