It [the Constitution] didn't break free from the essential constraints that were placed by the founding fathers in the Constitution, at least as it's been interpreted, and the Warren court interpreted it in the same way that generally the Constitution is a charter of negative liberties. It says what the states can't do to you, it says what the federal government can't do to you, but it doesn't say what the federal government or the state government must do on your behalf. And that hasn't shifted.

I look at some of the kids that I interact with, and they were born with so many disadvantages. And you could start off in your first interaction with them saying, "Unless they get a lot of compensatory help, they're not going to be able to compete; they're just so far behind, and they're wounded and they're hurt."

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.

One of the things that we have to change in this country is the idea that people can't disagree without challenging each other's character and patriotism. I have never suggested that Sen. McCain picks his positions on national security based on politics or personal ambition. I have not suggested it because I believe that he genuinely wants to serve America's national interest. Now, it's time for him to acknowledge that I want to do the same. Let me be clear: I will let no one question my love of this country.

Filibuster has long tradition, but used to harm civil rights.

The only people who don't want to disclose the truth are the people with something to hide.

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.
