I'm very pleased we got that nuclear agreement. It puts a lid on the nuclear weapons program. We have to enforce it, there have to be consequences attached to it. But that is not our only problem with Iran.

We also have to look at how we help families balance the responsibilities at home and the responsibilities at business.

We should demand that Donald release all of his tax returns so that people can see what are the entanglements and the financial relationships that he has with the Russians and other foreign powers.

On the spending, don't forget bridges and roads. It's like puppies and ice cream - who doesn't like them?

This is a very connected, tolerant, creative generation, but a lot of them feel really constrained because they've got this big debt.

The Russians and the Chinese have been absolutely clear they don't want to see Iran with a nuclear weapon.

I'm not responding to any of the personal attacks that come from Donald Trump, because he can say whatever he wants about me, and I have more votes than he does as we sit here today. More Americans have voted for me.
