Former CBS producer, Robert “Joe” Halderman, who was accused of trying to blackmail comedian David Letterman, has plead guilty.

Halderman was charged with second-degree grand larceny on Tuesday, and will face six months in jail, five years probation and 1,000 hours of community service.

“This is a serious sentence that properly reflects the crimes that Mr. Halderman has now admitted that he committed, and it is a fitting end to the case,” Letterman’s lawyer, Daniel J. Horwitz said in a statement.

During an episode of The Late Show with David Letterman last October, the host admitted to affairs with female staff members, and revealed the extortion plot against him.

Halderman, a CBS employee for 27 years, confessed to trying to extort $2 million from Letterman in exchange for staying quiet about the affairs.

“I would like to thank the District Attorney of Manhattan, Cyrus R. Vance Jr., the former District Attorney, Robert M. Morgenthau, the Special Prosecutions Bureau in the D.A.’s Office and the New York City Police Department,” Letterman said in a statement after Tuesday’s hearing.
