What's your take on the Benghazi incident?

I was just watching the 13 hours interview (on Fox right now) with some of the men Soldiers who were there fighting recounting the incident. What makes me the most mad about this incident was the fact that they were left there to fend for themselves when so many were available and capable of responding. The denial of extra security can be chalked up to poor judgement, the lying about the cause can be chalked up to "conflicting information" but IMO there is no excuse to leave men largely outnumbered and under attack for 13 hours when reinforcements were available. The fact that help was continually told to stand down is what to me is despicable and inexcusable.

Question: what was the President and Hillary doing at the time of the attack? What did they continue to do when they knew it was attacked? How did they try to cover it up? Why didn't they go after the attackers since they had a year to act? I have no trust in the current administration especially Hillary.
