Yes.

"There is the discussion about, you know, the Republicans again, and this ongoing effort that began hours after the attacks, when Mitt Romney put out a press release to try to take political advantage out of these deaths, or out of the attack in Benghazi, and, in a move that was maligned even by members of his own party," Carney said during a press briefing. "And from that day forward, there has been this effort to politicize it."
There was a crisis mentality right after the murder of Americans, NOT because of the attack, but, because Romney had the nerve to say something about it. That to me was very telling given the blatant lies coming from the administration claiming some video caused a spontaneous uprising. And the carnival barker is attempting to change the reality of what took place to Romney's comment right after the attack.
Romney had 'them' on the ropes but fumbled it when he got a second opportunity to expose the lies.
I think Romney shut up about the attack because the mother of one of those killed did not want her son’s death to become a political football. I understand him not wanting to go there. The media would have been all over the mother and making Romney appear so heartless. Her son did not have a political thought when he rushed to the rescue of Americans in danger. Also, they shut him up by handing him false presidential briefings at that point. (I am guessing at the false part.)
