MANHATTAN — The former CBS television producer who tried to blackmail David Letterman is now out of jail.
Robert Halderman was released early from prison Thursday for good behavior after serving four months of his six-month sentence. He still has to serve 1,000 hours of community service.
Halderman was convicted of trying to extort $2 million from Letterman in exchange for the rights to a "screenplay" that would reveal the late night host’s alleged affairs with female staffers, one of whom was Halderman's ex-girlfriend.
The former producer’s lawyer told the Associated Press he was happy to be out of jail and is looking for a new job.
