Joint Chiefs of Staff Chairman Mike Mullen visited the Late Show with David Letterman last night for the very first time. The Navy Admiral is winding down his tenure as the military's top officer, and he's slated to retire October 1.
Letterman tried his best to pry information from Mullen about the Navy SEALS raid on Osama bin Laden's compound in Pakistan. And, with typical Letterman style, Dave was able to make something very serious very funny. He even threw in a Joe Biden joke.
