So Obama may have given Hillary a heads up on Bowe Bergdahl's swap but not Congress?

So did Obama have time to set up a lunch with Hillary Clinton to discuss the swap of five high profile terrorists for Bowe Bergdahl?  How can Obama then argue that he had to move too quickly to inform congress?

. . . President Obama met with his former secretary of State for lunch on Thursday, two days before it was announced that Bowe Bergdahl had been released from captivity in exchange for five high-profile Taliban prisoners.
They are also suspicious that Obama may have informed Clinton, the likely Democratic frontrunner for the White House in 2016.Republicans are furious that they were not told of the deal in advance, and argue that this broke U.S. law.The White House has said it will not give a read out of Obama’s lunch with Clinton, calling it a private event.
But that has only made Republicans more curious about the timing between the lunch, and the controversial prisoner swap.
“If Mrs. Clinton remains politically active, people will want to know what her advice was on the subject,” said Sen. Jeff Sessions (Ala.), a senior Republican on the Senate Armed Services Committee.
Sen. Lindsey Graham (R-S.C.), a member of the Senate Armed Services Committee, said questions about the meeting are fair game. . . .
