If you are starting to feel the chilly fall weather, take heart. David Letterman told his studio audience that it was far chillier in his home.
"I would give anything to be hiking on the Appalachian Trail," he joked, in a reference to S.C. governor Mark Sanford whose dramatic extramarital affair had been a previous prime target for Letterman.
Letterman continued to use his late night talk show as a platform to discuss how he "has his work cut out for him" in dealing with the fallout from his on-air confession that he was the alleged victim of extortion.
He also made nods to his past bashing of Bill Clinton and Eliot Spitzer by beginning a joke and trailing off before the punchline.
The audience seemed largely sympathetic, laughing and applauding as he made jokes about how he spent his weekend, "raking his hatemail."
Joe Halderman, 51, an Emmy-award-winning producer for CBS News' "48 Hours," has pleaded not guilty after he was charged last week with trying to blackmail Letterman for $2 million. Halderman allegedly claimed he had evidence of the talk show host's sexual affairs with staff members.
According to a source close to Letterman, the relationships Halderman was allegedly going to reveal occurred before Letterman's March 2009 marriage to Regina Lasko, with whom he has a son, Harry Joseph Letterman.
During Monday's taping of "Late Show," Letterman, 62, apologized for the unwanted attention that has bombarded his staff.
"I'm terribly sorry that I put the staff in that position," he told the studio audience. "The staff here has been wonderfully supportive to me, not just through this furor, but through all the years that we've been on television and especially all the years here at CBS, so, again, my thanks to the staff for, once again, putting up with something stupid I've gotten myself involved in."
He also talked about how the scandal has affected his relationship with Lasko.
"She has been horribly hurt by my behavior, and when something happens like that, if you hurt a person and it's your responsibility, you try to fix it," he said. And at that point, there's only two things that can happen: either you're going to make some progress and get it fixed, or you're going to fall short and perhaps not get it fixed.
By and large, members of his studio audience were rooting for Letterman. Sort of.
One woman said that while she was "impressed" with the way Letterman was handling the growing scandal and embarrassment, she wasn't handing him any pity points.
"I have sympathy for his wife. You know he's an adult, he made the choice, he put his family in jeopardy. He's got a young son out there, so it's got to be bad," said Hattie Lefkowitz. "But…do I feel sorry for him? No!"
Halderman's lawyer, Gerald Shargel, told "Good Morning America" today that Letterman's on-air confession was hardly the final word on the matter.
"Joe Halderman was at CBS for 27 years. Here's a guy who was an investigative journalist for so many years," Shargel said. "To say he was trapped in an extortion plot was kind of preposterous."
Halderman's attorney said that the late-night comedian's talk-show confession did not tell the whole story.
"I'm here to say, 'Not so fast," Shargel said. "I look forward to cross-examining David Letterman, because I don't think the full story is before the public. There's much more to this story." Freed on $200,000 bail, Halderman faces up to 15 years in state prison if convicted.
