NEW YORK, Dec. 30 (UPI) -- Joe Halderman, the U.S. television producer who pleaded guilty to blackmailing David Letterman for $2 million, is now working for "On the Case with Paula Zahn."
Halderman served four months of a six-month jail sentence last year for trying to extort money from the late-night comedian in exchange for his silence regarding affairs the married Letterman had with female members of his staff.
