Congressional caucus

The largest caucuses are the party caucuses and conferences in the United States Congress, which are the partisan caucuses comprising all members of one house from one party (either the Democrats or the Republicans) in addition to any independent members who may caucus with either party. These are the House Democratic Caucus, House Republican Conference, Senate Democratic Caucus and Senate Republican Conference. The caucuses meet regularly in closed sessions for both the House of Representatives and the Senate to set legislative agendas, select committee members and chairs and hold elections to choose various floor leaders. They also oversee the four Hill committees, political party committees that work to elect members of their own party to Congress.

Ideological congressional caucuses can represent a political party within a political party. In the United States two-party dominant political system, these congressional caucuses help congregate and advance the ideals of a more focused ideology within the two major relatively big tent political parties. Some caucuses are organized political factions with a common ideological orientation.[3] Most ideological caucuses are confined to the House of Representatives.

^ Total counts may vary as members are not limited to membership in a single caucus. The provided numbers are also those of known members of their respective caucuses and this does not necessarily reflect the true numbers (which can easily be higher).

Among the most visible caucuses are those composed of members sharing the same race or ethnic group. The most high profile of these represent people of color. The Congressional Black Caucus, Congressional Hispanic Caucus, and the Congressional Asian Pacific American Caucus also form the Congressional Tri Caucus when they sit together.

• The Congressional Black Caucus for African-Americans
• The two Hispanic caucuses:
  • The Congressional Hispanic Caucus for Hispanic Democrats only (Hispanic Republicans are barred from membership per 2000s rule change)
  • The Congressional Hispanic Conference for Hispanic Republicans, who formerly belonged to the Hispanic Caucus but later split off to form the Hispanic Conference
• The Congressional Asian Pacific American Caucus represents members who are Asian Americans and Pacific Islanders but are open to other members as well

The ERA Caucus (Equal Rights Amendment Caucus) was formed March 28, 2023, by Reps Ayanna Pressley and Cori Bush to affirm the ERA as the 28th Amendment of the US Constitution,[4] having met all requirements of Article V in 2020 with the ratification by the 38th state, Virginia.[5] The Caucus has quickly grown to be one of the largest in the US House, standing at 69 members in May of 2023.

The ERA Caucus quickly showed their support of the ERA, marching on April 28, 2023 to the Senate in support of S.J. Res 4, the bill to Affirm the ERA.[6]

The formation of the Congressional LGBT Equality Caucus was announced on June 4, 2008, by openly gay members of congress Tammy Baldwin and Barney Frank.[7][8] The mission of the caucus is to work for LGBT rights, the repeal of laws discriminatory against LGBT persons, the elimination of hate-motivated violence, and improved health and well-being for all persons, regardless of sexual orientation, gender identity, or gender expression.[9] The caucus serves as a resource for Members of Congress, their staffs, and the public on LGBT issues.[9]

The LGBT Equality Caucus admits any member who is willing to advance LGBT rights, regardless of their sexual identity or orientation; it has historically been co-chaired by every openly-LGBT member of the House. The caucus had 194 members, all of them Democrats, in the 118th United States Congress.

The most common caucuses consist of members united as an interest group. These are often bipartisan (comprising both Democrats and Republicans) and bicameral (comprising both Representatives and Senators). Examples like the Congressional Bike Caucus works to promote cycling and the Senate Taiwan Caucus promotes strong relationships with Taiwan.

The House Committee on House Administration (HCHA) prescribes certain rules for Congressional Member Organizations (CMOs). Each Congress,[nb 1] CMOs must electronically register with the Committee on House Administration, providing the name of the caucus, a statement of purpose, the CMO officers and the employee designated to work on issues related to the CMO. The HCHA rules include the following:

• Members of both the House and Senate may participate in CMO, but at least one of the officers of the CMO must be a Member of the House. The participation of Senators in a CMO does not impact the scope of authorized CMO activities in any regard.
• CMOs have no separate corporate or legal identity. A CMO is not an employing authority. The Members' Representational Allowance may not directly support a CMO as an independent entity. A CMO may not be assigned separate office space.
• Neither CMOs nor individual members may accept goods, funds, or services from private organizations or individuals to support the CMO. Members may use personal funds to support the CMO.
• A member of a CMO may utilize employees (including shared employees) and official resources under the control of the member to assist the CMO in carrying out its legislative objectives, but no employees may be appointed in the name of a CMO.
• CMOs may not use the frank (congressional free mailing) privilege, nor may a member lend their frank to a CMO.
• A member may use official resources for communications related to the purpose of a CMO. Any such communications must comply with the franking regulations.
• Members may devote a section of their official website to CMO issues, but CMOs may not have independent web pages.
• A member may use inside mail to communicate information related to a CMO.
• Members may prepare material related to CMO issues for dissemination.
• Official funds may not be used to print or pay for stationery for the CMO.
• Members may refer to their membership in a CMO on their official stationery.
