No he didn't. He and his synchophants CLAIMED that it was the video after-the-fact, and they did so only to cover up their inaction.
Obama's view is the same as that of the militant islamofascists - kill the infidels. He chose not to react because he wanted the other team to win. The other team is his team.
Obama didn't provide help because muslims would have died.
Of course, there is also that theory that suggests this was all a staged kidnapping in which Obama planned to become a hero by negotiating a release...and the plan went awry when the kidnapping got out of control and the kidnappers killed the Ambassador. That said, I don't think Valerie Jarrett would let Obama pull a stunt like that, though I wouldn't be surprised if someone suggested it.
