Schumer's Roberts Questions: you can see and hear it here, go to the video/audio section in the middle of the page, scroll down a bit and just click on the Day 3, afternoon session. The thing is more than 5 hours long, but just go to 4:57:00 and the Schumer part starts right after Feinstein ends. its less than 15 minutes, but I wish it was longer...
NB: I just double checked, and the aforementioned is not the correct part-- go actually to 2:03:07 (you may have to start a minute earlier). It gets really good at about 2:07...
