In the letter, Mr. Halderman claimed he needed to “make a large chunk of money” by selling Mr. Letterman a purported “screenplay treatment,” prosecutors said. The screenplay treatment said Mr. Letterman’s “world is about to collapse around him” as information about his private life was about to be disclosed and that the disclosure would lead to a “ruined reputation,” prosecutors said.
Mr. Halderman, 52 years old, later demanded $2 million in a meeting with Mr. Letterman’s attorney, prosecutors said. Mr. Letterman and his lawyer then contacted the district attorney’s office.
“I knew throughout this time I was not engaging in a legitimate business transaction with Mr. Letterman and that what I was doing was against New York law,” Mr. Halderman said. “I understand that my attempt to extort $2 million from Mr. Letterman violated his and his family’s privacy. I promise to respect their privacy in the future.”
Mr. Halderman was arrested in October, a day after Mr. Letterman admitted on CBS’s “The Late Show With David Letterman” that he had had sexual relations with female members of his staff.
