Always try to learn from other people's mistakes, not your own- it is much cheaper that way!

Barack Obama can't beat ISIS. He's a lousy president.

I watched what this man [Cruz] did to Dr. Ben Carson, who I respect, in Iowa, where he said that Ben Carson is out of the race - he has left Iowa and he's out of the race. And I thought it was disgraceful.

I have nothing to do with Russia. Haven't made a phone call to Russia in years. Don't speak to people from Russia. Not that I wouldn't. I just have nobody to speak to.
