When Donald Trump's projects go under, the first people that don't get paid are the contractors that he's - some of whom have gone bankrupt. They're calling me. I'm getting nonstop e-mails and calls now from people that have been scammed by Donald Trump. And their stories are heartbreaking.

I think strong rhetoric and strong action are two separate things. Anyone can use tough words. Anyone can go over the top and say things that sound strong. But sounding strong is not enough. You have to know exactly how you're going to do it. And if you look at some of the policies he's talked about, they would not make America stronger.

Our government does not exist to decide the rights, nor to grant them. Our government exists to protect them. And that is why we have a constitution that limits the power of the federal government to a few specific, but important things and we have abandoned that. We have abandoned it in both political parties.

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.

This president [Barack Obama] is undermining the constitutional basis of this government. This president is undermining our military. He is undermining our standing in the world....The damage he has done to America is extraordinary.

[Cuba's goverment] is an anti-American government.

Cubans must prove that they're political refugees. And if they can prove that they're really fleeing persecution, well, they would qualify as refugees.
