Let's be clear about what this [presidential] campaign is about. It's not about Donald Trump, he's an entertaining guys, he's the greatest show on Earth.

If you're running to be president of the United States, you can't just tell people you're going to make America great again. I think you need to begin to explain exactly how you're going to do it policy-wise. We're not going to win a general election with a candidate that refuses to detail policy.

We will either bring on another American century, or we are doomed to witness America's decline.

ISIS is winning the propaganda war. They are recruiting people, including Americans, to join them, with the promise that they are joining this great apocalyptic movement that is going to defeat the West.

The problem is, if El Chapo builds a tunnel under the fence, we need to deal with that too.

I think we need to simplify our tax code, but not as a way of generating revenue, as a way of making our tax code more growth- friendly.

Everything that I will ever accomplish, I owe to God, to my parent's sacrifices, and to the United States of America.
