I'm told that the mood at today's holiday lunch at the NPR West studios in Culver City turned dark as a rumor swept the place that "Day to Day" and "News and Notes" would be shut down. No official word from National Public Radio, but a source in Culver City says VP for News Ellen Weiss is coming out next week to swing the hatchet. If true, and apparently most there believe it's true, the move would eliminate the two NPR shows produced locally and pretty much make the spiffy new Jefferson Blvd. studios unnecessary. Stay tuned.
