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—comprises 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, regardless of its population size, is equally represented by two senators who serve staggered terms of six years. There being at present 50 states in the Union, there are currently 100 senators. 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.
