Blumenthal: Benghazi attack carried out by 'Islamist militia group'

The latest release of emails from Hillary Clinton's time as secretary of state show Clinton being informed of the possibility that the Sep. 11, 2012 Benghazi, Libya attacks had "Islamist" origins as early as Sep. 13, 2012.

Clinton confidant Sidney Blumenthal wrote Clinton just after midnight on Sep. 13, 2012: "On September 12, 2012 Libyan President Mohammed Yussef el Magariaf told senior advisors that the death of the U.S. Ambassador at the hands of Islamist militia forces represents a threat to the future of the newly elected General National Congress (GNC) Government."

Blumenthal continued, "Libyan security officials believe that the attack was carried out by forces of the Islamist militia group calling itself the Ansar al Sharia brigade; working out of camps in the Eastern suburbs of Benghazi."

"These officials do believe that the attackers having prepared to launch their assault took advantage of the cover provided by the demonstrations in Benghazi protesting an internet production seen as disrespectful to the prophet Mohammed," Blumenthal wrote.

Clinton insisted that Blumenthal's email be printed, and then had it disseminated to staff.

The State Department would later state in October 2012 that no such protest actually occurred, and the Defense Department confirmed that the Benghazi attack was an act of premeditated, Islamist terrorism as early as Sept. 27, 2012.
