I cite the actual bill and you cite a news article as though that somehow trumps it. The bill says what it says, and that's what Congress actually did. (That being said, the quotes in the linked news article still only refer to release not transfer.) Congress did nothing to impede transfer until December 2010. Individual Congressmen giving hysterical quotes is not a "block" on the administration.
Disagree with the latter half of that statement, obviously. If Mr. Obama becomes apoplectic when individual Congressmen make hysterical quotes, he should not have run for the Presidency. It's certainly not an excuse for inaction.
