This paper examines the organizational structure of the United States Congress, focusing on the committee system and leadership hierarchy of both chambers. It explains the origins of the modern committee system in the 1946 Legislative Reorganization Act and distinguishes among standing committees, select committees, joint committees, and subcommittees. The paper also outlines the leadership structures of the House of Representatives and the Senate — including the Speaker, Majority and Minority Leaders, and Whips — and compares the two chambers in terms of their exclusive powers, partisan tendencies, and deliberative styles.
The structure of the United States Congress was developed to address the high degree of specialization required in the nation's legislative dealings. The two chambers — the House of Representatives and the Senate — have committees set up to deal with specialized issues. Each chamber has a leadership structure that facilitates the needs of the two parties, and the committees also have their own leadership hierarchies.
Within Congress, much of the most important work is done in committee. The congressional committee system is composed of over 200 committees and subcommittees, divided by functional grouping, with each committee holding expertise in certain specific subject matter. The role of each committee is to "gather information about the subject; to compare and evaluate legislative alternatives; to identify policy problems and solutions; to select, determine and report measures for full chamber consideration; to monitor the executive branch and to investigate allegations of wrongdoing" (Heitshusen, 2007).
The congressional committee system as we know it today dates from the 1946 Legislative Reorganization Act. Committees exist in both the House and the Senate, with four committees being joint committees with members from both chambers. In addition, Congress has both permanent committees and special committees to address issues that fall outside the scope of any permanent committee. At present, Congress has 20 standing committees with 97 subcommittees and two select committees. This count does not include task forces, party committees, and other informal groups.
Standing committees have legislative jurisdiction over their subject area. Their functions include the consideration of bills, which may then be recommended to the full House or Senate. Standing committees also have jurisdiction over monitoring agencies within their field and recommend funding levels.
Select committees examine issues that are not part of any specific existing standing committee. When an issue cuts across jurisdictional boundaries, a select committee may be formed to address it. These committees may or may not be permanent in nature. A joint committee is comprised of members of both the House and the Senate. For the most part, joint committees handle routine issues and conduct studies, while the substantive legislative work is left to the standing or select committees.
Subcommittees operate within a standing or select committee but typically focus on only one task or issue. The overarching committee sets the framework for the subcommittee's activities, including its mandate and operational rules. In Congress, subcommittees are generally limited to five or six per committee. The function of subcommittees varies more widely than that of full committees, as they tend to operate with fewer constraints. This leads to a high degree of autonomy for some subcommittees, while others have only limited independence. Those with a high degree of autonomy play a more direct role in shaping legislative outcomes.
