I think Americans have every reason to be worried about ISIS and the network of terrorist groups, because they have proven to be sophisticated and effective in wreaking violence and murder in many parts of the world, including in San Bernardino with their somehow connected radicalization of that couple there.

We have to make it easier to be good workers, good parents and good caregivers all at the same time. That's why I've set out a bold vision to make quality, affordable child care available to all Americans and limit the cost to 10 percent of family income.

I'll get involved in philanthropy.

We are desperately in need of the kind of smart diplomacy that has worked for America in the past. If you use force, it should be a last resort. And it needs to be used with full understanding of the consequences.

The bottom line on nuclear weapons is that when the president gives the order, it must be followed. There's about four minutes between the order being given and the people responsible for launching nuclear weapons to do so. And that's why 10 people who have had that awesome responsibility have come out and, in an unprecedented way, said they would not trust Donald Trump with the nuclear codes or to have his finger on the nuclear button.

I would love having the job of president because I know how to do it. I know what the country needs.

There's a certain consistency to who I am and what I do, and I think people have finally said, 'Well, you know, I kinda get her now.' I've actually had people say that to me.
