I have a comprehensive energy policy, but it really does include fighting climate change, because I think that is a serious problem.

The United States compared to a number of our competitors is the only government in the world with any kind of safeguards, any kind of checks and balances. They may in many respects need to be strengthened and people need to be reassured, and they need to have their protections embodied in law.

What's great about America is anybody can run for president. That is literally true.

I think it's understandable that when questions are raised, people maybe are thinking about them and wondering about them, but I have every confidence that during the course of this campaign, people are going to know who will fight for them, who will be there when they need them, and that's the kind of person I am and that's what I will do, not only in a campaign but as president.

It would be impossible to be fact-checking Donald Trump all the time.

I need people to know that there is a group of people who are part of the leadership of the DNC, and I will make damn sure as a vice chair, and so will others, that we do everything humanly possible to have a level playing field.

It is often the case that laws must change before fears about change dissipate.
