Petraeus knew that it was likely terrorism and not a demonstration gone wild. If he misled Congress about that, that's a problem, but we know he knew. And we also now know that this was included in the CIA's assessment that went out to other agencies. Somewhere between that assessment leaving the CIA and reaching Rice, that information got redacted. We do not yet know by whom. If that information got redacted before Obama saw it, well, that's a problem, isn't it? Shouldn't the CnC be getting the best information, even if there's a reason to hide it from the public?
But we also have reports that Obama DID receive this information. But the White House and Rice spent a lot of time publicly claiming that the attack was a demonstration gone wild. Why then did they do this? Maybe there's a good answer to that, but one has not yet been forthcoming.
