Committees are used in Congress to divide up legislative work, as Congress receives around 10,000 bills per year. Most legislative work is done in committees, which are comprised mostly of the majority party. Committee chairs are the most senior member of the majority party on the committee. They determine the committee's agenda and manage floor debates. There are several types of committees, including standing committees that consider specific subject matter areas, select committees for specific purposes, and joint committees with members from both the House and Senate.
