For a controversy which has played in so many committee rooms the factual narrative of events in Benghazi seems pretty hard to follow and has been largely subsumed in partisan assumptions. The State Department Accountability Review Board report gives an impressively coherent blow-by-blow of the tragic events at the Special Mission compound; though it fails to mention, by name, the CIA operation it is publicly alleged that the ‘mission’ was largely established to conceal and protect:
The U.S. effort in Benghazi was at its heart a CIA operation, according to officials briefed on the intelligence. Of the more than 30 American officials evacuated from Benghazi following the deadly assault, only seven worked for the State Department. […]
The CIA worked from a compound publicly referred to as the “annex,” which was given a State Department office name to disguise its purpose. The agency focused on countering proliferation and terrorist threats, said an American security contractor who has worked closely with CIA, the Pentagon and State. A main concern was the spread of weapons and militant influences throughout the region, including in Mali, Somalia and Syria, this person said.
