Seems John McCain was scheduled to be on Letterman tonight. He called at the last minute this afternoon to cancel due to the financial crisis. Letterman finds out that when McCain should have been sitting on the couch talking to him, he was at NBC taping a segment with Katie Couric. Keith Olbermann stepped in to substitute. Letterman is beyond pissed.

From the New York Times:

Even after Mr. Letterman brought out Keith Olbermann, the MSNBC host and vituperative Republican critic as the substitute guest for Mr. McCain, he continued to assail Mr. McCain for the decision to cancel the appearance. His critique reached a high point when he learned that at the very moment Mr. McCain was supposed to be on the couch next to him being interviewed, the senator was at the CBS News center three blocks away in Manhattan, getting ready to be interviewed by the CBS News anchor, Katie Couric.

Mr. Letterman ordered his director to put on a live feed from that location, which showed Mr. McCain getting made up to go on with Ms. Couric. “He doesn’t seem to be racing to the airport,” Mr. Letterman observed.

After listening to some questions from Ms. Couric, Mr. Letterman said, “Hey, John, I’ve got a question: You need a lift to the airport?”
