On March 1, 2007, a subcommittee of the Committee on Government Reform held a hearing on the bill HR1255, the Presidential Records Act Amendments of 2007. This bill was introduced by Waxman, and its goal was to void Executive Order 13233.At the hearing, several historians argued that Order 13233 has severely curtailed public access to presidential records and added to delays in obtaining materials from presidential libraries. The bill was reported favorably by the full committee, and on March 14, 2007, the House passed the bill in an overwhelmingly bipartisan vote of 333-93. The bill also passed on June 13, 2007 in a Senate committee, but was never brought to the floor for a vote, reportedly due to a hold placed on the measure by Senator Jim Bunning (Republican- Kentucky)
