WASHINGTON, DC - JANUARY 31:  Senate Armed Services Committee member Sen. Angus King (I-ME) questions former U.S. Senator Chuck Hagel (R-NE) during his confirmation hearing to become the next secretary of defense on Capitol Hill January 31, 2013 in Washington, DC. President Barack Obama nominated Hagel, a controversial choice as Hagel opposed former President George W. Bush and his own party on the Iraq War and upset liberals with his criticism of a gay ambassador, for which he later apologized.  (Photo by Chip Somodevilla/Getty Images)
