We think about the enormous costs of homelessness, or the enormous cost of HIV/AIDS, over the long term, as people visit emergency rooms, etc. The more we are investing in that ounce of prevention the better off we're going to be.

My expectation would be that if we can begin discussions soon, shortly after the Iranian elections, we should have a fairly good sense by the end of the year as to whether they are moving in the right direction.

I do make sure that I've got people who are experts that are helping me make the best decisions possible.

When it comes to immigration, I think Americans expect that our immigration process is orderly and it is legal.

Going back to the discussion we were having about immigration reform, some of the most challenging discussions I've had are with activists who essentially would argue that any immigrant from Central America, let's say, who gets here to this country should be allowed to stay because their country is dangerous, their country is poor, and the opportunities for that mom and that kid are much greater here, and why would you send them back?

The United States is imposing sanctions on individuals and companies working to advance Iran's ballistic missile program, and we are going to remain vigilant about it. We're not going to waver in the defense of our security or that of our allies and partners.

We can't drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times... and then just expect that other countries are going to say OK. That's not leadership. That's not going to happen.
