The meeting also came just a day after Graham told The Hill that the U.S. should consider boycotting the 2014 Winter Olympics in Russia if authorities there decided to offer asylum to Edward Snowden, the former Defense contractor who has claimed responsibility for leaking classified information about top-secret National Security Agency surveillance programs.

White House press secretary Jay Carney would not categorically rule out a boycott on Wednesday, despite admitting he thought it was a bad idea. But Graham stood by his suggestion when talking to reporters yesterday afternoon.
