The moot court process in our office when we get ready, we - everybody, including the SG, does two moot courts for each argument. And they are phenomenal, and they predict 90 percent of the questions that I get asked, at least 90 percent.

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.

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'm arguing for progressive positions on behalf of a progressive administration in front of a court who, before Justice [Antonin] Scalia's death, had a conservative majority that was quite conservative, frankly.

I had a great deal of independence from the president and the White House during the entirety of my five years. And I'm not sure exactly what that is, but our friend, Walter Dellinger, has a theory about it, and I think he's probably right. And the theory starts with the fact that I worked in the White House for a year and a half before coming over to the position of SG. And because of that, when I was nominated, there was some chatter out there that, "Oh. They're putting a political hack in. This has never happened before."

I do a little bit of hand-holding on the big cases. You know, like health care, I'll call over and say, "Don't worry. We've got it under control. We have the best people working on it. We're on schedule. Stay calm." So, those kinds of things.

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.
