I don't think we need to have an either/or debate about the use of military force - I think you can be both tough and smart.

What I believe is the more we can do for the middle class, the more we can invest in you, your education, your skills, your future, the better we will be off and the better we'll grow. That's the kind of economy I want us to see again.

I don`t control the schedule of the networks. We have three of our debates that are on network television, and those are on Saturday nights. We have three other debates that are during the week. And unfortunately, broadcast network programming is less flexible than cable network programming.

The Republicans want to repeal the Affordable Care Act, I want to improve it. I want to build on it, get the costs down, get prescription drug costs down. Senator Sanders wants us to start all over again. This was a major achievement of President [Barack] Obama, of our country. It is helping people right now.

When I became secretary of state, we had 200,000 troops deployed in Iraq and Afghanistan. And I'm very grateful that we have brought home the vast majority of those.

I think we have to take a look at corporate law. We have to take a look at the incentives that we can perhaps use to encourage more longer term.

We do have the nuclear weapons agreement with Iran, that's an enforcement consequence, action for action, follow on. We have a plan, we will watch them, we will be vigilant.
