David Letterman Rants About John McCain Cancellation (Video)

David Letterman seemed a tad upset about John McCain's last minute cancellation so he could return to Washington to work on the economic crisis.

“This doesn’t smell right,” Letterman quipped. “This is not the way a tested hero behaves. Somebody’s putting something in his Metamucil.”

The late night host's rant didn't end with the opening monologue. When MSNBC host Keith Olbermann took the couch, Letterman learned McCain was getting ready for an interview with CBS new anchor Katie Couric at the very moment he was supposed to be taping the show with him.

With a live feed from Couric's interview on the screen, Letterman said,  “He doesn’t seem to be racing to the airport."

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

Asking Olbermann if he thought this was all McCain’s fault, or whether other factors had come into play, the MSNBC host replied, "I think he ditched you."
