It sounds like Rush Limbaugh is making an appearance in FNC's news satire pilot:

"I went out and did some television Saturday in Los Angeles," the radio host said on Monday. "There's a new show that probably will air soon, I'm not sure when, but it's called The Half Hour NewsHour. That's the working title of it now. I guess that's subject to change. Well, actually it's not, because if it changes I gotta go back out there, but nevertheless it's a parody newscast, takeoff on liberal media newscasts, and I play the president of the United States in the opening segments of this program.

I went out and shot three takes. Ann Coulter is the vice president. (laughing) It's hilarious. The whole thing is hilarious..."
