FILE - In this June 25, 2009 file photo, Sen. John McCain, R-Ariz. watches as President Barack Obama meets with members of Congress to discuss immigration, in the State Dinning Room of the White House in Washington. Obama and McCain, the Republican he defeated in his first White House campaign, have become one of Washington's most talked about odd-couple pairings. And like any successful business deal in the nation's capital, the relationship works because it has benefits for both men. (AP Photo/Haraz N. Ghanbari, File)
