I know. Gingrich said it and for the life of me, I don’t know why. Then again, I don’t know a lot of things.
Since Tuesday now several at Fox have mentioned an alleged private comment by Petraeus, to an unidentified congresscritter at the Congressional hearings, to the effect of: do you want the truth of the matter, or just the official line?
If the story is true, it implies Petraeus knew at the time his report of a video-inspired "flash mob" was just a cover story, intended to hide important secrets.
In that case, my guess would be: only some of those secrets involved national security, the rest were needed to cover political backsides of officials caught asleep on watch.
