FILE - This Dec. 30, 2012 file photo shows Senate Minority Leader Mitch McConnell of Ky., followed by Sen. Pat Roberts, R-Kansas leaving the Senate chamber on Capitol Hill in Washington. President Barack Obama says he won’t let Republicans threaten a debt ceiling crisis to extract deeper federal spending cuts, but congressional Republicans say he has no choice. The tough talk suggests this year's political fight could be even nastier and more nerve-grating than the "fiscal cliff" showdown.  (AP Photo/J. Scott Applewhite, File)
