I've met with a group of very distinguished, experienced police chiefs a few weeks ago. They admit it's an issue. They've got a lot of concerns.

Donald Trump said that every undocumented person would be subject to deportation. Now, here's what that means. It means you would have to have a massive law enforcement presence, where law enforcement officers would be going school to school, home to home, business to business, rounding up people who are undocumented. And we would then have to put them on trains, on buses to get them out of America.

I don't spend my hours plotting for somebody else's downfall.

I think because I really didn't have a good strategy for my campaign. I didn't plan it the right way. ... As a candidate who was already so well known ... I don't think I ever said, 'Yes, you may have known me for eight years, but I don't take anything for granted. I have to earn your support.

It's really hard to get to know me, or any candidate. And I would be asked questions like, well, why are you really running for president?

[Donald] Trump is obsessed with name calling.

If the FBI is watching you for suspected terrorist links, you should not be able to buy a gun with no questions asked.
