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."

If you've ever been in the West Wing, it's like a little rabbit warren. Everybody's crammed in there on top of each other, and you're eating breakfast, lunch, and dinner at the mess with people. And so you really get to know each other very well. So, I think they just weren't worried.

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.

After a couple of years, I realized that this was actually true, that his gave me the ability to go to a different place and, hopefully, have a stronger impact.

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.

People have got to make their best calls in what they think about a case when they're covering it. But I do think the lesson there, and I guess stating the obvious, that oral argument can as often send a false signal as an accurate signal about where the thing is going.

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.
