In the U.S. House of Representatives, members form voluntary associations that are officially called Congressional Member Organizations and unofficially referred to as caucuses. These caucuses organize around identity or interest in order to pursue policy, signal identification, or boost a member’s public bona fides in some manner. When these caucuses are formed, members of the House are required to register them with the Committee on House Administration.

Our previous list of caucuses formed in the early days of the 112th Congress can be found here. Below are the newest Congressional Member Organizations, a crop of 51 recognized by the House Administration Committee since February 15, 2011. As part of an effort to increase the transparency of these CMOs, we have done our best to locate websites and membership lists for each caucus. We also note the caucuses for which websites and membership are unavailable, making their existence and activities opaque to the American public.
