We have a government that borrows $4 billion a day. We have a government that owes trillions of dollars in debt, half of that to foreigners, most of that to Chinese investors. I don't - that is extreme. Not only is it extreme. It's insane and it's unsustainable.

It is hard for me to imagine retiring at 65 and spending the next quarter century not working. I expect to be working, doing something productive and fulfilling.

Immigration is not an issue that I read about in the newspaper or watch a documentary on PBS or CNN. It's an issues I've lived around my whole life. My family are immigrants. My wife's family are immigrants. All of my neighbors are immigrants.

I think the immigration system we have now is terrible for the United States of America. We have a legal immigration system that does not work. It does not reflect the economic needs of this country in the 21st century. It needs to be modernized.

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.

We are a people that have always celebrated other people's success so long as we always had the opportunity to meet that success ourselves. That is the American nature. That is the American character. That is one of the things that makes us different from the rest of the world. And I'm afraid we could lose that or are on the verge of losing that.

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.
