Banning all Muslims will make it harder for us to do exactly what we need to do, which is to destroy ISIS. We need a strategy. We need to get the lawyers off the back of the warfighters.

There's got to be a point where we fix the system so that legal immigration is easier than illegal immigration and show respect for people, a kid who might have been here for 10 years, that might be a valedictorian of their high school to say, no, no, no you're not allowed to go to college. I just think there's a point past which we are over the line.

Donald [Trump], is great at - at the one-liners, but he's a chaos candidate.

I haven't been in Washington over the last - ever. I'm not part of Washington. I got to serve as governor of a state, a purple state and I was the most successful conservative governor probably, during the time that I was there.

We can grow economically and restore America's leadership in the world, so that everybody has a chance to rise up.

If we're going to ban all Muslims, how are we going to get them to be part of a coalition to destroy ISIS?

That, by the way, is perhaps the most ludicrous comment I've ever heard, that climate change is a bigger threat to our country than radical Islamic terrorism.
