David Letterman 'didn't want Late Show return after 9/11'
The host's return to the air in the aftermath of the terrorist attacks was credited with reassuring the other late-night hosts of reviving their own series.
In an interview with Piers Morgan Tonight guest host Regis Philbin, Letterman disclosed that he had serious reservations about reviving The Late Show in the wake of such a tragedy.
"I remember not wanting to go back, not feeling ready to go back, but knowing we had to go back," Letterman recalled. "And you know - my concerns were minimal compared to people who really suffered."
Letterman also discussed his political beliefs, admitting that he has shown bias in his jokes on occasion.
"I have been guilty of appearing to be playing partisan politics. However, I'd just like to say that for the record, I am a registered independent," he commented.
The host said of mocking political leaders: "No president that I am aware of got hammered harder than Bill - President Bill Clinton - over the Monica Lewinsky situation.
"We beat up on him. We still use him as a reference, and then we were desperate. We thought, 'Well, this was so easy' - and then we got George Bush."
The Late Show with David Letterman airs weeknights on CBS.
