Jeb Bush on Sunday's edition of State of the Union on CNN:
JAKE TAPPER, CNN'S "STATE OF THE UNION" HOST: So, what are you objecting to about Mr. Trump's remarks about 9/11 and your brother?
JEB BUSH: Look, my brother responded to a crisis, and he did it as you would hope a 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's -- 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 that -- as though he's 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, is just -- this is just another example of the lack of seriousness.
And this is a serious time. We're under -- we're under grave threats again, and I think we need a president with a steady hand.
TAPPER: To play devil's advocate, do you think it's at all possible that your loyalty to your brother, while very admirable on a personal level, might be in some ways a political or policy liability, blinding you to mistakes he made?
I mean, so, next week, Mr. Trump is probably going to say that FDR was around when Japan attacked Pearl Harbor. It's what you do after that matters. And that's the sign of leadership. It's not -- it's not the -- does anybody actually blame my brother for the attacks on 9/11? If they do, they're totally marginalized in our society.
It's what he did afterwards that mattered, and I'm proud of him, and so are a bunch of other people. You don't have to have your last name the -- name Bush to be able to understand that.
And it just calls into question Mr. Trump's credibility as a commander in chief and an architect of a next -- you know, the next-generation foreign policy, which we desperately need in this country right now.
