Everybody spies on everybody, I mean, that's just a fact.

Leadership can not be measured in a poll or even in the result of an election. It can only be truly seen with the benefit of time. From the perspective of 20 years, not 20 days.

If we capture any of these ISIS killers alive, they are going to Guantanamo Bay, Cuba, and we're going to find out everything they know, because when I'm president, unlike Barack Obama, we will keep this country safe.

I believe that the bigger problem is that we're seeing people who arrive from Cuba and a year and a day later are travelling to Cuba 40 times a year, they're staying, and that's hard to justify. The problem is not that I want to deny anything to anyone; it is the need to justify those laws.

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.

There is one way, only one way to solve it, and that is through legislation. It cannot be through an unconstitutional executive order that violates the Constitution. That is, it doesn't matter here what you think about immigration: here you cannot violate the nation's Constitution, period.

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