Justices Scalia, O'Connor, and Breyer shoot the shit with Tim Russert about important junk. This broadcast on Thursday, but it is being replayed at 6 PM on Saturday night. If you actually have a life and are going out on Saturday night, watch it via this link.
It is RealPlayer, so it might be worth staying home to not deal with it. There is a long "commercial" at the beginning with Peter Jennings. Just ignore him. I have for many years.
EDIT: the rerun is on CSPAN, not CSPAN2
