U.S. President Barack Obama (L) stands near Senator John McCain (R-AZ) before a dinner for committee chairmen and other congressional leaders at the White House in Washington in this March 4, 2009 file photo. McCain lost the 2008 presidential election to Obama but his passion to rein in government spending has assured him a leading role in Republican efforts to shape Obama's economic revival plans.
