Acongressional caucus is a group of members of theUnited States Congress that meets to pursue common legislative objectives. Formally, caucuses are formed asCongressional Member Organizations (CMOs) through theUnited States House of Representatives and governed under the rules of thatchamber. Caucuses are informal in the Senate, and unlike their House counterparts, Senate groups receive neither official recognition nor funding from the chamber. In addition to the term caucus, they are sometimes calledcoalitions, study groups, task forces, or working groups.^[1] Caucuses typically have bipartisan membership and have co-chairs from each party.^{[citation needed]} Chairs are listed below the name of each caucus.
