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.

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 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.

It's the spring of 2012, that the [Barak] Obama administration would be embracing the argument that the Affordable Care Act was a tax, and that was going to, itself, be a political albatross.

I'm representing the United States. And I'm representing the United States, and my office is representing the United States day after day in front of the court. And I think it's the right thing to do, to carry that out with some dignity and some respect for the process and respect for the institution. And so that led me to just, you know, move the dial a little bit in the direction of calmness.

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.

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.
