That's because that's not what Rush does. He's a commentator, not an interviewer. Once in a while he'll have one person or another on for a few minutes, but he absolutely isn't a journalist. He's a commentator, and he states it baldly. He's there to get the facts out and explain them. Not to eat up time letting this person and that present their side of anything. He takes what they say elsewhere and he puts it out there.
