In late October, Petraeus traveled to Libya to conduct his own review of the Benghazi attack that killed four Americans, including U.S. Ambassador Christopher Stevens.
While in Tripoli, he personally questioned the CIA station chief and other CIA personnel who were in Benghazi on Sept. 11 when the attack occurred.
The Libya stop was part of a six nation trip to the region. Petraeus intended the review as a way to prepare for his upcoming testimony before Congress on Benghazi.
