Benghazi Betrayal May be a Cover-Up of American Weapons in Hands of Terrorists
I think Frank Gaffney hits the nail on the head. Basically, Obama is likely guilty of treason by way of giving aid and comfort to the enemy:
The evidence suggests that the Obama administration has not simply been engaging, legitimating, enriching and emboldening Islamists who have taken over or are ascendant in much of the Middle East. Starting in March 2011, when American diplomat J. Christopher Stevens was designated the liaison to the opposition in Libya, the Obama administration has been arming them, including jihadists like Abdelhakim Belhadj, leader of the al Qaeda franchise known as the Libyan Islamic Fighting Group.
