At last night’s presidential debate, undecided voter Kerry Ladka questioned President Obama about the terrorist attack in Libya and security for Americans in Benghazi. The ensuing exchange resulted in one of the most memorable moments of the evening.

With many Americans seeking answers about the killing of Ambassador Christopher Stevens and three other Americans on September 11, Obama once again failed to explain why it took his Administration so long to acknowledge the attack was an act of terrorism. Heritage’s video, released last week, chronicles the Administration’s changing story after the attack.

Heritage’s James Jay Carafano commented last night:

What did the Administration do about security before the attack on the U.S. consulate in Benghazi, and how did it respond afterward? It was the question that the President never clearly and explicitly responded to. When it comes to how the White House responded to the attack, the Administration has a lot of explaining to do. Its series of explanations was muddled and misleading.

Evidence shows there were security threats in Benghazi in the months prior to the deadly September 11 terrorist attack. Despite these threats, the Obama Administration and State Department left its personnel there to fend for themselves.
