An uncharacteristically somber David Letterman went public with his own sex scandal on The Late Show Thursday night, confessing he had had sex with female members of his staff.

Letterman said he was the victim of a $2 million extortion attempt by a CBS producer. A producer for the CBS news program 48 Hours has been arrested on charges of grand larceny in the first degree.

The talk show host, 62, shared part of his testimony to the grand jury yesterday morning: “I had to tell them all of the creepy things that I had done … The creepy stuff was that I have had sex with women who work for me on this show.” Letterman married his longtime girlfriend — a former Late Show staffer — in March. The couple have a young son.

Letterman says he found a package in the backseat of his car three weeks ago with a letter saying, “I know that you do some terrible, terrible things and that I can prove you do some terrible things.”
