I asked Secretary [Robert] Gates, what did they get in return for giving up the nuclear shield of Poland and the Czech Republic? And you know what his answer was? Nada. They got nothing.

I'd rather have a genius like Donald Trump running America than someone like Hillary Clinton.

She [Hillary Clinton] was extremely careless with handling national security information.If she were just an ordinary person, she would be denied a top security clearance because she has proved in her past acts that she is extremely careless in handling national security information.

And it's a little - very humbling to think that running for president of the United States is - for a kid from Brooklyn, it's quite a step.

I would ask [protesters] to please respect - I'd ask them to please respect the democratic process.

The minute Putin went into Crimea, what Obama should have done is sent 50,000 troops to NATO. He didn't have to engage them, just send them. That puts the fear of God into people.

I think Donald Trump's reaching out and supporting John McCain and Kelly Ayotte in particular, and Paul Ryan, who had been critical of him, you know, a couple of days earlier, shows that he has the ability and the understanding to realize that there are going to be disagreements and you've got to be able to reach out to the entire party.
