Here’s the scoop from the Chicago Tribune:

David Letterman acknowledged on Thursday’s show that he had sexual relationships with female employees and that someone tried to extort $2 million from him over the affairs.

During the taping of his CBS late-night show in New York, Letterman discussed receiving a threat to either pay $2 million or risk the relationships being made public.

In a release from the show’s production company, Letterman said he referred the matter to the Manhattan district attorney’s office and that an investigation ended in an arrest Thursday. Letterman did not identify the person he said was arrested.

As part of the investigation, Letterman said he issued a “phony” $2 million check to the individual and the arrest followed — along with testimony by Letterman.

This one really didn’t take me by surprise.  I really don’t have much to say.

It’s Thursday night, and I’m watching his opening monologue now.  He sounds fine.  I suspect we’ll hear more than we care to about all of this in the days and weeks ahead.
