Washington, November 11 The man accused of trying to extort money out of comedian David Letterman over his sexual affairs with female staffers has asked a New York judge to dismiss the case.

Letterman confessed having bedded a number of his female co-workers and issued a public apology to his wife Regina Lasko on his 'Late Show with David Letterman'.

He approached authorities telling them that he was being blackmailed to pay 2 million dollars to keep the information out of the public domain.

The alleged extortionist was exposed as producer Robert Halderman who was later taken into custody.

And now, an attorney for Halderman requested for a dismissal of his client's indictment saying he was "trying to make a 'hard-driven' deal to sell rights to a screenplay inspired by Letterman's sexually-charged workplace", reports Us magazine.

According to the New York Daily News, lawyer Gerald Shargel argued Halderman observed that "Letterman had created and fostered an environment of workplace sexual misconduct that under any definition amounted to actionable sexual harassment." (ANI)
