Caucuses of the United States Congress

A congressional caucus is a group of members of the United States Congress that meets to pursue common legislative objectives.

Formally, caucuses are formed as Congressional Member Organizations (CMOs) through the United States House of Representatives and governed under the rules of that chamber.

Caucuses are informal in the Senate, and unlike their House counterparts, Senate groups receive neither official recognition nor funding from the chamber.
