The world is a dangerous place. And it's a more dangerous place than it was seven years ago [before Obama].

I think that in terms of the American interests, I would feel more safe with a President Trump representing those interests to the world.

No one doubts that Donald Trump is willing to walk away from a deal if it's a bad one. No one doubts that he's willing to punish our enemies if they transgress U.S. interests, whereas, with Hillary Clinton, she is very predictable.

I have had the advantage of the opportunity to meet with Mr. Trump on several occasions. And my experience is that he's very intelligent. He's thirsty for information. He wants to hear what you have to say. He listens to his advisers. He digests the information very quickly, and he's got a good memory, because I remember one time I was talking to him about something, and then he pulled some information out of his memory banks that was a great connection that I hadn't even thought to mention to him.

Different presidents are different as far as their public persona vs. their persona meeting with advisers. For example, George Bush was pretty much the same in person as when he was speaking publicly. I think Donald Trump has a stage persona and he also has a temperament when meeting with his advisers. Now, the positions are the same, but the attitude is a little bit different.

For a long time, there has been lingering doubt among many Americans about integrity and fairness of elections. And it's not a new issue at all. If you look at polling data, it goes back decades.
