When you have people that are cutting Christians' heads off, when you have a world that the border and at so many places, that it is medieval times, we've never - it almost has to be as bad as it ever was in terms of the violence and the horror, we don't have time for tone. We have to go out and get the job done.

I believe we should sunset our visa laws so that Congress is forced to periodically revise and revisit them to bring them up to date. They're archaic. They're ancient. We wouldn't put our entire federal budget on auto pilot for decades, so why should we do the same for the very, very complex subject of immigration?

Hillary Clinton is only talking about families who come here in violation of the law. We will treat everyone living or residing in our country with great dignity. So important.

I don't want people to chop off the citizens' or anybody's heads in the Middle East, OK? Because they're Christian or Muslim or anything else.

I think building the middle class, investing in the middle class, making college debt-free so more young people can get their education, helping people refinance their - their debt from college at a lower rate. Those are the kinds of things that will really boost the economy.

The only thing Hillary Clinton has going for herself is the press, without the press, she is absolutely zero.

Anything greater than 350 of parts of carbon dioxide per million is more than the planet can safely deal with. It is what's overwhelming our climate system. Because we've been going up about three parts per million per year. And eventually, we will always be above 410, and then above 420, and above 430. We just keep pouring more carbon into the atmosphere.
