Sharyl Attkisson: CBS News has been told that, hours after the attack began, an unmanned Predator drone was sent over the U.S. mission in Benghazi, and that the drone and other reconnaissance aircraft apparently observed the final hours of the protracted battle.
The State Department, White House and Pentagon declined to say what military options were available. A White House official told CBS News that, at the start of the attack, Chairman of the Joint Chiefs Martin Dempsey and Defense Secretary Leon Panetta “looked at available options, and the ones we exercised had our military forces arrive in less than 24 hours, well ahead of timelines laid out in established policies.”
But it was too late to help the Americans in Benghazi. The ambassador and three others were dead.
A White House official told CBS News that a “small group of reinforcements” was sent from Tripoli to Benghazi, but declined to say how many or what time they arrived.
