Remember your boy Bush failed to prevent a bunch of people getting killed. I believe it was a lot more than at Benghazi. It was preventable too.
BTW; the official 9/11 commission report does not say the 2001 attacks were preventable, unlike the Senate Intel Committee Benghazi report. Where is your all-important proof you always ask for of others after such declarations? Got anything official from anyone higher than the 9/11/2001 commission, or beyond someone's mere opinion? No.....you don't.
