He blamed the Youtube video.
That is all we really need to know about the guy.
He also blamed Terry Jones for the riots in Afghanistan instead of focusing on killing the enemy.
Was he being blackmailed to say that it was the YouTube video? Was he deliberately kept out of the loop as Benghazi unfolded in real time because of his "security breaches"? Lots of interesting questions still awaiting answers. Not that the press is interested in providing them.
You don't know that. Get back to me when you have real hard evidence that he did.
