I think what we need to do is understand our number one obligation is to act in the national interest of the United States of America. I believe it is in our national interest to see democracy take hold on the island of Cuba. And so we examine our foreign policy, including all the changes that President Obama made, in that lens and through that lens.

I owe a debt to America that I will never be able to repay.

Certainly being governor is an important job, and there are quality governors that could serve our country as president and have done so in the past.

ISIS is a radical jihadist group that is increasingly sophisticated in its ability, for example, to radicalize American citizens, in its inability to exploit loopholes in our legal immigration system, in its ability to capture and hold territory in the Middle East, as I outlined earlier, in multiple countries.

First, undoubtedly, there are some people who are coming from Cuba who immediately, or from any other country, benefit. But, what is the difference between that and someone who is coming from Nicaragua, Guatemala, Mexico, etc.? That is, we are simply going to say that someone who comes from another country to the United States - the first five years they're here - they don't qualify for federal benefits. They may benefit from local benefits, state benefits. Those decisions belong to other jurisdictions.

Donald Trump is not going to be the nominee, because we are not going to allow - people will wake up and we're not going to allow a con artist to take over the party of [Abraham] Lincoln and [Ronald] Reagan.

They're willing to accept changes on the part of the U.S. that contribute to more money entering Cuba so they can benefit. But in terms of political changes on the island, an opening, etc., that won't happen, that won't change, and I've always said that, from the beginning. I've even said that it doesn't matter how many tourists who to Cuba, how many times the President visits Cuba; there won't be any changes in the Cuban government's posture. And that is the same as always.
