When people say, well, they disapprove, I'd like to know what the specifics are, because sometimes - and the president [Barack Obama] has admitted this - they may not feel like he's really explaining and understanding the emotion behind some of these fears [about Iran].

But if you look at the results of where we are, I think there are some things I agree with and some things I don't agree with, and I think that's absolutely fair game.

Donald Trump is not a normal presidential candidate.

Every presidential candidate for decades has released his tax returns, and I've released 33 years of my tax returns. The American people deserve to know about our taxes.
