My job was always to pull a vote over from somebody who was likely to be at least at the outset disinclined to agree with me on some things or at least disinclined to agree with the policy that I was defending.

I do think it's true that a huge amount of the oversight that the White House engages in with respect to the Executive Branch is out of fear that somebody's going to do something crazy and drive the president off a cliff.

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.

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.

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.

I feel so blessed to have had the chance to do this job [ U.S. Solicitor General] in this moment in our history. It's been an incredible thing.
