Everything here is as published by Congress. Seats run from the 107th Congress, dated by the resolutions that made them and the Congressional Record; referrals and nominations from the 107th; meetings from the 112th. A committee older than that shows less than it has done. A subcommittee's referrals are recorded against it separately from its parent's, so the two lists do not add up. Records come from Congress.gov, GovInfo and the House and Senate.
