Senate Appropriations Committee
The Senate Appropriations Committee is the largest committee in the U.S. Senate, with 30 members at the end of the 111th Congress. Its role is defined by the U.S. Constitution, which requires "appropriations made by law" prior to the expenditure of any money from the Treasury, and is therefore one of the most powerful committees in the Senate.
