What we once thought of as necessary and proper reasons for ostracizing and marginalizing gay people, we now understand do not justify that kind of oppression.

The president [Barak Obama] had been asked some questions by George Stephanopoulos on a news show about whether it was a tax. And he had given an answer that you might read as him saying it wasn't a tax. I think what he said was, "It isn't a tax increase on all Americans."

There was only really one time that I had a substantive interaction with the president [Barak Obama] directly, and that was in 2013 when we were deciding whether to file a brief in the first gay marriage case, the Perry against Hollingsworth case. That was a weighty decision about whether the United States government was going to come in and say that heightened scrutiny ought to apply and some state bans on same-sex marriage ought to be unconstitutional. And that was the one time in my tenure where I thought I ought not make this decision without talking to the president.

Justice [Sonia]Sotomayor said, "Let's talk - you want to talk about the tax power."And I got like a 10-minute run on the tax power. And, boy, was I glad I did because I was able to get across this idea that, yes, this is a narrower ground on which you can affirm it. And I think everybody agrees. I think even the dissenting justices ultimately in the case agreed that, if Congress had expressly called it a tax, it would be indisputably constitutional.

The cases involving the question of whether U.S. courts should be open to claims of international human rights violations brought by foreign persons against foreign government officials. And the State Department on the one side has got a very consistent and powerful view that U.S. courts should be open to those claims because there needs to be a place in the world where they can be brought. And those human rights norms ought to be real and enforceable, and we ought to be a beacon to the world.

One thing I've experienced and I feel really grateful for now that I'm on my way out is that I felt that the justices gave that back to me. I really did. You know, of course, you can have some sharp exchanges. That's the nature of the thing, and that's fine. But really in the main I felt like the tone from them was, "Yeah. We may not agree with you, but we're going to have a discussion about this." And it did.

There was this point about, you know, the basic point there as well - this statute treats some parts of the country different from others, and what's the justification for that? Well, you know, I had eight million things to say about that, but he put it in such a sharp, excruciating way that it was just very hard to handle it effectively.
