Following Halderman's court appearance, David Letterman released a statement through his spokesman thanking the DA . “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. When they became involved with this case, I had complete faith that a just and appropriate result was inevitable. On behalf of my family, I am extremely grateful for their tireless efforts.” (New York Times)
Halderman attempted to extort two million dollars from David Letterman, threatening to reveal Letterman's extramarital affairs..The fall-out from the blackmail case led to increased public attention for Letterman, and higher TV ratings for Letterman's show.
