David Letterman Gets Feisty

After hearing about it all night finally there's video of David Letterman's annoyance with Sen. McCain suspending his campaign, canceling his appearance on Letterman's show claiming he was headed straight to D.C. and then doing an interview with Katie Couric of CBS News at the same time he was supposed to arrive for his taped appearance. It's pretty fair to say Letterman was not pleased.
