Extortionist Robert Joe Halderman was blackmailing David Letterman earlier this year but just recently was released from jail. Robert was trying to extort $2 million from David. He was threatening to expose an extramarital affair that had happened on the set of “The Late Show.” David ended up turning Robert into the police and confessing to the dirty deeds he did on the show.  He was sentenced to six months in jail but due to good behavior, he was released two months early, only serving four.  Even though Robert was released early he will still have to complete 1,000 hours of community service, and keep his nose clean for four and a half years of probation.
