When we're not a party, we sometimes file as amicus, as friend of the court, 25, 30 times a term, sometimes more. And in each of those cases, we've got to decide what position the government's going to take. And that is the solicitor general's job to make that decision.

I think what happened is that everybody's impressions got formed in those first few minutes. And I felt like, by the latter part of it, I kind of clawed my way back into the discussion. But everybody's impressions were set at the beginning. And wholly apart from me and whether I was good or bad, you know, there were a lot of hostile questions.

I don't think this is a situation where you can say that Congress was avoiding any mention of the tax power. It'd be one thing if Congress explicitly disavowed an exercise of the tax power. But given that it hasn't done so, it seems to me that it's - not only is it fair to read this as an exercise of the tax power, but this court has got an obligation to construe it as an exercise of the tax power if it can be upheld on that basis.

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.

The part that the public sees is the arguments up at the podium and the briefs that we file. But a significant part of the job - in fact, I'd say I spend more of my time on this part of the job, which is deciding what the position of the United States will be in the cases that we're going to be participating in before the court.

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.

Very quickly the lawyers in the Justice Department pulled together a set of recommendations about how we ought to defend the law as a constitutional matter. And it was the lawyers in the Justice Department who thought that it was important to include the tax power argument as part of it.
