Russian Track Team Barred from Olympics

RUSH: I just saw that the Russian track team has been banned from the Olympics. The male track team. Why would that be? I just saw. I have no idea why. Is there doping scandal? (interruption) Oh, you'd heard about this? I just saw it. You knew about this before I saw the headline. I can understand if the East German women's team had been banned, but they don't exist anymore. They're now prison guards Siberia.
