What's important to do is we must deal frontally with this threat of radical Islamists, especially from ISIS. This is the most sophisticated terror group that has ever threatened the world or the United States of America.

Here is the thing people do not understand. And I have said this repeatedly. I am not against changes in U.S. policy towards Cuba. I just want to make sure that those changes are reciprocal, that they're reciprocated by the Cuban government. That was not part of what President Obama did.

The children of the Reagan Revolution are ready to assume the mantle of leadership.

We call that the American dream, but in fact, it's a universal dream of a better life that people have all over the world. It is a reminder that every country in the world has rich people. What makes America special is that we have millions and millions of people that are not rich, that through hard work and perseverance are able to be successful.

Let me just say the rules are what they are in the Republican Party. You have to have X-number of delegates in order to be the nominee. And if you don't have those number of delegates, then there's a process in place.Here is what would be a calamity, for Donald Trump to become our nominee.

Obviously I don't agree with everything he [Donald Trump] says. There's a lot that we have a difference of opinion on. But we can't ignore that he's touched on some issues that people are concerned about. If you look at the statements he made this week, obviously I think he made them partially to recapture the limelight after having lost it.

I do think we lost some of the focus on the attacks in San Bernardino and focused on a plan that isn't really a plan and is never going to happen.
