A congressional committee is a legislative sub-organization in the United States Congress that handles a specific duty. Committee membership enables members to develop specialized knowledge of the matters under their jurisdiction. As "little legislatures", the committees monitor ongoing governmental operations, identify issues suitable for legislative review, gather and evaluate information, and recommend courses of action to their parent body. Woodrow Wilson once wrote, "it is not far from the truth to say that Congress in session is Congress on public exhibition, whilst Congress in its committee rooms is Congress at work." It is not expected that a member of Congress be an expert on all matters and subject areas that come before Congress. Congressional committees provide valuable informational services to Congress by investigating and reporting about specialized subjects.

The United States Congress is the legislature of the federal government of the United States. It is bicameral, composed of a lower body, the House of Representatives, and an upper body, the Senate. It meets in the U.S. Capitol in Washington, D.C. Senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a governor's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The U.S. vice president has a vote in the Senate only when senators are evenly divided. The House of Representatives has six non-voting members.
