I think what is true is that there's been an underlying division in the United States. Some of it has to do with the fact that economic growth and recovery tends to be stronger in the cities and in urban areas. In some rural areas, particularly those that were reliant on manufacturing, there has been weaker growth, stagnation, people feeling as if their children won't do as well as they will.

I think that what is always true when you run against an incumbent president is, is that you end up talking more about that president's record than your vision for the future, and I think that the Democrats do have to present a proactive agenda and vision for the country and not simply run against something if they're going to be successful.

If you think that we've overregulated in the environmental space what I can show you is that we have tripled the amount of wind power in this country, increased by tenfold the amount of solar power. We are producing as much oil and gas as we've ever produced.

We do not benefit from a relationship with China or any other country in which we put our values and our ideals aside.

We can get this done! Take a vote, and send me that bill.

I think that [Donald Trump] clearly was able to tap into a lot of grievances. And he has a talent for making a connection with his supporters that overrode some of the traditional benchmarks of how you'd run a campaign or conduct yourself as a presidential candidate. What will be interesting to see is how that plays out during the course of his presidency.

Whatever decisions I make are going to be based first on a strategy to keep us safe and then we'll figure out how to resource it.
