In a speech at the University of Denver, Paula Broadwell gave out some possibly classified information about a CIA center in Benghazi. Specifically she mentioned that there were members of the Libyan militia being held there, and the attack on the Embassy might have been connected with an effort to get them released.
This coincides with statements that libyan militia members were turned over to authorities of that country on September 12th, after the attacks.
Broadwell told her audience that Petraeus knew almost immediately that the Embassy was attacked by terrorists. Petraeus testified in a closed congressional meeting that the Benghazi attack was spontaneous, and motivated by the anti Islam video.
