I don't like to sit back and gloat, because the world is fragile. Life is fragile, so I never really gloat.

You have to remain cool under fire and let criticism roll off you. Good leaders handle conflict easily and bad ones are eaten up by it.

I think maybe there's a political reason why Hillary Clinton can't say it, but I really don't believe - in New York City, stop-and-frisk, we had 2,200 murders, and stop-and-frisk brought it down to 500 murders.

I have no relationship with Vladimir Putin.

The criminal conduct of Hillary Clinton threatens the foundations of democracy.
