Well, it was reported on 9/12 that Obama had a meeting for with NSA in WA DC at 5PM on 9/11. I remember wondering if it was an internet meeting.
Interesting. I hadn't heard that. Timing is right, since the attack began at 3:40 PM Washington time on 9/11.
However, there was a recent report where that direct question was asked of a White House spokesman (not Carney) and the response was a flat "decline to comment".
