WASHINGTON D.C. (KMOX) - Surveillance video of the attack at Benghazi Libya was shown to members of the Senate Intelligence Committee.

Senator Roy Blunt is a member of that committee. He told CNN. one of his big concerns is the large amount of time between the beginning of the attack and the end.

“The violence at the mission itself where the ambassador was killed happened relatively early but then there is a big block of time between then and the time the last two American lives are lost.” Sen. Blunt told CNN.

He was not specific about that time line, only to say the attack started in the evening and lasted into the next morning.

After seeing the surveillance video Senator Blunt still has questions about U.S. response capabilities and security at embassies.

“One of the questions we need to ask is why can’t we respond quicker than that, why can’t we get assistance to people quicker than that and obviously the ongoing question is why wasn’t there there more security.” said Senator Blunt.
