The House Democratic Caucus is a congressional caucus composed of all Democratic representatives in the United States House of Representatives, voting and non-voting, and is responsible for nominating and electing the Democratic Party leadership in the chamber. In its roles as a party conference, the caucus writes and enforces rules of conduct and discipline for its members, approves committee assignments, and serves as the primary forum for development of party policy and legislative priorities. It hosts weekly meetings for these purposes and to communicate the party's message to members.

The United States House of Representatives is the lower chamber of the United States Congress, with the Senate being the upper chamber. Together, they comprise the national bicameral legislature of the United States. The House is charged with the passage of federal legislation, known as bills; those that are also passed by the Senate are sent to the president for signature or veto. The House's exclusive powers include initiating all revenue bills, impeaching federal officers, and electing the president if no candidate receives a majority of votes in the Electoral College.
