On Capitol Hill yesterday, Defense Secretary Leon Panetta and Joint Chiefs Chairman Gen. Martin Dempsey testified before the Senate Armed Services Committee, which is looking into the Pentagon's response to the Sept. 11, 2012 attack on the U.S. Consulate in Benghazi.

The most revealing piece of information to come out of the testimony was when Panetta said

that President Obama was absent on the night of the attack, in which four Americans were killed. Panetta and Dempsey said they briefed Obama during a pre-scheduled meeting at 5pm ET on that day, as events in Benghazi had just started to unfold. They said there was no communication with the president until after the attack was over more than eight hours later.

Last night, Sean Hannity discussed Obama's absence with Sen. Lindsey Graham (R-S.C.), who questioned Panetta at length about why the president was apparently not engaged as the attack unfolded.

Hannity called the details of the president's whereabouts, "shocking," while Graham said eventually Obama "has to account for his leadership."

"This whole episode, if it had come out before the election - remember when Obama turned to Romney in the third debate and basically said, 'I know these people, I know their families, I know their names, I would never put them in harm's way?'. Well Mr. President, what did you do for eight hours? Who did you talk to?" Graham asked.
