Sen. Lindsey Graham on Sunday leveled conspiracy charges against the White House for attempting to cover up the Sept. 11 terrorist attack on the Libyan embassy that killed a U.S. ambassador.

Graham said on CBS’ “Face the Nation” he knows for a fact the administration was told within 24 hours of the incident it was carried out by al-Qaida operatives.

“They’re trying to sell a narrative, quite frankly, that the mid East, the wars are receding, and al-Qaida’s been dismantled,” the South Carolina Republican said. “And to admit that our embassy was attacked by al-Qaida operatives and Libya, leading from behind, didn’t work, I think undercuts that narrative. They never believed the media would investigate. Congress was out of session. It just caught up with them.”

If the administration is not misleading the public, then it’s response to the attack is “incredibly incompetent,” Graham said.

“They’re very political when it comes to foreign policy,” he said. “When something goes bad, they deny, they deceive, and they delay, and the truth is, we’re not safer. Al-Qaida is alive. [Osama] bin Laden may be dead.”
