JAKE TAPPER: What are you objecting to about Mr. Trump’s remarks about 9/11 and your brother?
GOV. JEB BUSH: Look, my the brother responded to a crisis and he did it as you would hope the president would do. He united the country, he organized our country and he kept us safe and there's no denying that. The great majority of Americans believe that and I don't know why he keeps bringing this up. It doesn't show that he's a serious person as it relates to being commander-in-chief and being the architect of a foreign policy. Across the spectrum of foreign policy Mr. Trump talks about things as though he is still on The Apprentice. I mean, literally talking about Syria saying ISIS should take out Assad, then Russia should take out ISIS as though it was some kind of board game and not a serious approach. This is just another example of the lack of seriousness and this is a serious time. We're under grave threats again and I think we need a president with a steady hand.
