Sometimes one of the justices, because they're, you know, they're brilliant lawyers themselves, can put the question in a particular way so that, even if you've prepared to talk about the topic, the question is put in such an excruciatingly difficult way that there's just no good way to handle it.

I do think that the instant nature of the reaction now, I do think it has an effect, that people's instant reactions to things are valid and valuable. But they're not always right, and they're not always capturing the full reality.

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.

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.

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.

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."

The fact that you have a policy of such consequence directly affecting millions of people and you have a legal question of great consequence about the scope of the president's authority to act in implementing the immigration laws in this way and you have a one-line decision from the court affirming by an equally-divided court, it's an inevitable consequence of where we are.
