A congressional subcommittee in the United States Congress is a subdivision of a United States congressional committee that considers specified matters and reports back to the full committee.
Subcommittees are formed by most committees to share specific tasks within the jurisdiction of the full committee. Subcommittees are responsible to, and work within the guidelines established by, their parent committees. In particular, standing committees usually create subcommittees with legislative jurisdiction to consider and report bills. They may assign their subcommittees such specific tasks as the initial consideration of measures and oversight of laws and programs in the subcommittees’ areas.[1] Service on subcommittees enables members to develop expertise in specialized fields. Subcommittees diffuse the legislative process. For the most part, they are independent, autonomous units with written jurisdictions, and, pursuant to longstanding practice, most bills are referred by a full committee to them.[2]
General requirements for establishing subcommittees are established in House or Senate rules, but specifics with respect to subcommittee assignments and their jurisdiction are left up to the parent committees.[3] Committees have wide latitude to increase or decrease the number of subcommittees from one congress to the next, including renaming or reassigning jurisdiction among previous subcommittees. Some committees, like the House and Senate Appropriations Committees, often retain a predictable subcommittee structure from year to year, due to the set duties of each subcommittee in drafting annual spending bills. However, even these committees are not immune to organizational changes. New subcommittees on Homeland Security were created in 2003 to handle funding for the Department of Homeland Security, and underwent a joint reorganization during the 110th Congress to better coordinate annual appropriations between the House and Senate.[4]
The respective party conferences in both the House and Senate also provide their own rules, traditions, and precedents with respect to the subcommittee assignments, chairmanship of subcommittees, and even the number of subcommittees members can serve on.
