Donald Trump: I would have prevented 9/11
Is this an exact quote or is CNN making up headlines again?
He never stated such a quote, and his statements aren't necessarily useful as anyone can state they could have prevented 9/11 in hindsight with what we now know.
His main thrust with this line of statements seems to me to be keeping the Bush name attached to Jeb, which is a good idea, although his tactics aren't necessarily the best route, but then again, he may be getting advice that leads him to believe this is a useful course of action.
