Robert Halderman

Robert "Joe" Halderman, the former CBS producer who was convicted of attempting to blackmail late-night TV host David Letterman, has been released from jail early. Halderman, who lived in Norwalk before his conviction, served four months of a six-month sentence and was release early for good behavior. He served his sentence on Rikers Island in New York. He still must complete 1,000 hours of community service and will be on probation for five years.

Halderman admitted he demanded $2 million in hush money from Letterman last fall to keep from revealing personal information about the TV host's affairs with CBS staffers.
