The United States Senate is one of the two houses of the United States Congress. The other house is the House of Representatives.
The composition and powers of the Senate are established in Article One of the U.S. Constitution. Each U.S. state is represented by two senators, regardless of population. Senators serve staggered six-year terms.
The Senate has several exclusive powers not granted to the House, including consenting to treaties as a precondition to their ratification and consenting or confirming appointments of Cabinet secretaries, federal judges, other federal executive officials, military officers, regulatory officials, ambassadors, and other federal uniformed officers, as well as trial of federal officials impeached by the House.
