I think the problem with John Bolton is he disagrees with President Trump's foreign policy. He would be closer to John McCain's foreign policy. John Bolton still believes the Iraq war was a good idea. He still believes that regime change is a good idea. He still believes that nation-building is a good idea.

I think this sets a very bad precedent, the president unilaterally on his own starting war without any consent from Congress.

I still say exactly what my original opinion is. Do you borrow money from China to send it to anyone? Out of your surplus, you can help your allies, and Israel is a great ally. And this is no particular animus of Israel, but what I will say, and I will say over and over again, we cannot give away money we don't have.

I'm the leading voice in America for not arming the allies of ISIS.

For liberty to expand, government must shrink. For the economy to grow, government must get out of the way.

Any time someone tries to tell you that metadata is 'meaningless, don't worry, it's just who you call, it's just phone records, it's not a big deal' - realize we kill people based on metadata. So they must be pretty darn certain that they think they know something based on metadata.

I’ve never argued against any technology being used when you have an imminent threat, an active crime going on. If someone comes out of a liquor store with a weapon and fifty dollars in cash, I don’t care if a drone kills him or a policeman kills him.
