 So, so with respect, I find that a curious statement because you gave a speech in April of 2015 at the University of Chicago in which you described the job you do as a judge. And you said sentencing is just plain interesting because it melds together myriad types of law, criminal law, and of course constitutional law, critical race theory. So you described in a speech to a law school what you were doing is critical race theory. And so I guess I would ask, what did you mean by that when you gave that speech? With respect, Senator, the quote that you are mentioning there was about sentencing policy. But I've never studied critical race theory and I've never used it. It doesn't come up in the work that I do as a judge.
