I think that is the speech I saw a long time ago, maybe 10 years. I was so impressed. I also followed the confirmation hearings. I think he’s great.
I think you are right. It was before 2003, and probably before 2000, but I saw it on CSPAN but could not find it archived. It was in front of about 20-30 students and was amazing... and the kids also seemed to be impressed!
