MANHATTAN - A judge in New York has refused to dismiss charges against the Norwalk man accused of attempting to blackmail David Letterman.

Prosecutors say Robert Halderman demanded $2 million from the talk show host to keep quiet about Letterman's affairs with staffers on the "Late Show."

Halderman had asked the judge to toss the charge Tuesday, saying he was only offering Letterman the chance to buy a thinly veiled screenplay about his life and keep it private.
