A central question of Fox News' latest documentary on Benghazi has already been answered by official congressional and State Department investigations into the terrorist attacks.

On August 27, Fox announced “13 Hours at Benghazi,” a new documentary hosted by Special Report anchor Bret Baier that will reportedly include “exclusive” interviews with three American security personnel who were present for the September 2012 attacks. The production, scheduled to air September 5, is based on a forthcoming book written by journalist Mitchell Zuckoff and the CIA contractors.

According to Fox's announcement, the production will specifically explore “Whether or not military assistance was requested by the security team and whether orders from above hindered their response to the violence that claimed the lives of U.S. Ambassador Christopher Stevens and three other Americans.”

The problem with this premise is that both of those questions have already been answered by official intelligence investigations.

As the Daily Beast's Eli Lake has explained, on the night of the attacks there was a 23-minute delay between the initial distress call from the diplomatic mission and when the CIA contractors departed the nearby Annex to respond. Despite suggestions from some in the intelligence community that this delay hindered their rescue effort, investigations found no evidence that the CIA operatives were delayed by “orders from above,” as Fox's announcement suggests.

Instead, the Senate Intelligence Committee's January 2014 review of the attacks found that during that delay, the CIA's Chief of Base “attempted to secure assistance and heavy weapons” from US allies in the region, and that (emphasis added):

Although some members of the security team expressed frustration that they were unable to respond more quickly to the Mission compound, the Committee found no evidence of intentional delay or obstruction by the Chief of Base or any other party.

The State Department's independent Accountability Review Board also found the CIA team was not obstructed by officials:

The departure of the Annex team was not delayed by orders from superiors; the team leader decided on his own to depart the Annex compound once it was apparent, despite a brief delay to permit their continuing efforts, that rapid support from local security elements was not forthcoming. 

Finally, the House Intelligence Committee, chaired by Republicans, also found no evidence that any response effort was blocked by official orders. According to Rep. Dutch Ruppersberger (D-MD), the “bipartisan, factual, definitive report” on the Intelligence Community's actions the night of the attacks “shows there was no 'stand down order' given to American personnel attempting to offer assistance that evening.”

Fox's Bret Baier, the host of the upcoming special, reported on the House Intelligence Committee's findings on August 5.

Baier has hosted previous Fox specials on Benghazi and has repeatedly used his Fox News program to promote myths about the attacks and their aftermath. The false claim that CIA contractors received “orders to wait” was also pushed by 60 Minutes' infamous since-retracted Benghazi report, which featured a discredited “eyewitness” account from a British security contractor.
