I think it's important to understand that ISIS's biggest enemy are ordinary Muslims. That's why they're fleeing.

I think the blood is spilling in Syria and it's mostly Muslims.

Republicans advising candidates to "grab onto the best elements of [his] anti-Washington populist agenda," but warning that Trump is a "misguided missile," "subject to farcical fits" and candidates should avoid getting drawn into "every Trump dust-up," but should quickly condemn some of his comments, including "wacky things about women."

I admire many people, but I am not sure that I have any 'heroes.'

I don't think there's any clever way for the establishment to take Donald Trump down. It's very simple. Another candidate is going to have to find a way either to out-maneuver him, or to just frankly beat him in the argument.

We don't know yet but so far the three candidates that have dealt with [Donald] Trump most adeptly are [Ted] Cruz, [Chris] Christie, and [Marco] Rubio. But they've all avoided him in one form or another.

There are many other [then ISIS] terrorist organizations. And their primary victims are Muslims. I think that's very important.
