The latest incriminating information on the U.S. consulate attack in Benghazi, Libya indicates that the State Department turned down a request for additional security from concerned U.S. embassy staff.

New evidence shows there were security threats in Libya in the months prior to the deadly September 11 attack that killed U.S. Ambassador Christopher Stevens and three other Americans. Despite these threats, the State Department left its personnel there to fend for themselves.

And when the terrorist attack did take place, the Obama Administration peddled the ridiculous story that an offensive, amateurish, anti-Islam YouTube video was to blame in order to avoid characterizing the murders of four Americans as terrorism.

On October 2, a letter was sent to Secretary of State Hillary Clinton from House Oversight and Government Reform Committee Chairman Darrell Issa (R–CA) and Jason Chaffetz (R–UT), Chairman of the National Security, Homeland Defense and Foreign Operations Subcommittee. The letter detailed 13 known security threats against U.S. facilities in Libya in the six months prior to September 11.

On October 10, the committee will hold a hearing on events in Libya and seek answers from the State Department. Also on October 10, The Heritage Foundation will host a public panel discussion on the events in Libya titled, “Intelligence and Security Failure: Attacks in Benghazi and Across the Middle East Reveal Ongoing Threat of Terrorism.”
