David Letterman joked with Katie Couric about Rush Limbaugh's address to the Conservative Political Action Conference (CPAC). "What about this bonehead Rush Limbaugh? Honest to God, I mean, what is going on there?

He gets up in Washington and he's the keynote speaker at some function and he comes up and he looks like an East European gangster. He's got the black jacket on, the black silk shirt and it's unbuttoned like, oh yeah, when you think Rush Limbaugh, you think, 'Ooh, let's see a little flesh.' Honestly. What is he doing?" Letter asked Couric.

Laughing, Couric replied, "although I'm thrown by the Rush Limbaugh flesh in the same sentence... it's indicative of the power vacuum in the Republican party right now and he's filling it right now..."
