Elsewhere, the debate on tax reform will continue during a pair of hearings on Capitol Hill as lawmakers continue to wrestle with how to whip the tax code into shape.

The following day, the Senate Budget Committee will hear from a set of experts about the efficiency of the tax code.

On Wednesday, the House Financial Services Committee will mark up two bills that would spell the end of two more of the administration’s housing relief programs. Last Thursday, Republicans on the panel pushed through two similar bills, as they aim to take down foreclosure mitigation programs they deem ineffective and costly.

Also Wednesday, the Senate Finance Committee will welcome U.S. Trade Representative Ron Kirk to discuss the administration’s 2011 trade agenda.
