Investigations into the 2012 Benghazi attack

[15] On November 7, 2013, Representative Devin Nunes (R-CA) wrote a letter to House Speaker John Boehner a week ahead of congressional hearing with CIA contractors who were on the ground during the attack.

[22] As required by the Omnibus Diplomatic and Antiterrorism Act of 1986, the State Department established on October 4, 2012, an Accountability Review Board "to examine the facts and circumstances of the attacks".

[28] Homeland Security and Governmental Affairs Committee Chairman Joe Lieberman (I-CT) and Ranking Member Susan Collins (R-ME) opened an investigation in mid October 2012.

[34] In a September 29, 2015, Fox TV interview with Sean Hannity, Kevin McCarthy, then in the running for Speaker of the House, said, "Everybody thought Hillary Clinton was unbeatable, right?

"[35] Many media outlets and Democratic lawmakers interpreted this comment as an admission that the investigation was a partisan political undertaking rather than a substantive inquiry.

[37][38][39] The New York Times reported, "the long day of often-testy exchanges between committee members and their prominent witness revealed little new information about an episode that has been the subject of seven previous investigations.

[44] On May 3, 2013, Stephen Hayes wrote in The Weekly Standard, "senior Obama administration officials knowingly misled the country about what had happened in the days following the assaults.

[46] The changes made to the talking points,[47] according to the report, appear to directly contradict what White House Press Secretary Jay Carney said about them in November 2012.

[48] On the May 19 episode of ABC News' This Week, Karl announced he regretted reporting the inaccuracy and acknowledged that he exaggerated the words Obama speechwriter Ben Rhodes had written in one of emails cited in the documents.

[46] On July 11, Nuland, who was nominated by Obama to be the top US envoy to Europe, told various members of the Senate Foreign Relations Committee during a confirmation hearing that she had made the revisions and that she had feared Republicans in Congress would politicize the original memos and present a false impression that various top US State Department officials, including then-Secretary of State Hillary Clinton, had covered-up information about the attack.

[50] In August 2013, it was reported by Drew Griffin and Kathleen Johnston of CNN that dozens of CIA operatives were on the ground in Benghazi on the night of the attack.

They further reported that according to their sources the agency was going to great lengths to keep what they were doing a secret, including polygraphing some of the survivors monthly in order to find out if they were talking to the media or Congress.

Based on "months of investigation" and "extensive interviews with Libyans in Benghazi who had direct knowledge of the attack there and its context", the investigation found "no evidence that Al Qaeda or other international terrorist groups" had any role in the assault, but that the attackers included militias that "benefited directly from NATO's extensive air power and logistics support" overthrowing Colonel Qaddafi, and whom the Americans "had taken for allies".

Dozens of people joined in, some of them provoked by the video and others responding to fast-spreading false rumors that guards inside the American compound had shot Libyan protesters.

Looters and arsonists, without any sign of a plan, were the ones who ravaged the compound after the initial attack, according to more than a dozen Libyan witnesses as well as many American officials who have viewed the footage from security cameras.

"[53][54] In April 2014, Seymour Hersh published an essay in the London Review of Books in which he explores an anonymous former Pentagon official's claims that the U.S. diplomatic post in Benghazi "had no real political role" and existed solely to provide cover for a secret arms pipeline supporting Syrian rebels fighting in the Syrian civil war.

[55] According to Hersh's source, the "rat line" was a means for channeling military weapons, including surface-to-air missile launchers (MANPADS), from Gaddafi's arsenals into Syria and into the hands of Syrian rebels.
