Four members of Army special forces ready to head to Benghazi, Libya, after the deadly assault on the American diplomatic mission had ended were told not to go, according to a former top diplomat.

Gregory Hicks also argued in an interview with Republicans on the House Oversight and Government Reform Committee that if the U.S. military had flown aircraft over the Benghazi facility after it came under siege it might have prevented the second attack on the CIA annex that killed two CIA security officers.
