The newsletter for the local chapter of the National Television Academy offers some clues about why KTVU anchor Leslie Griffith has been missing from the station’s newscasts for seven weeks. The newsletter says her problems with management began when she criticized how her script was written — on the air. Griffith said something to the effect of “Can you believe how poorly this story is written?” Nobody is quite sure what she said because tapes of the show were immediately pulled off the station’s shelves and never returned. “But that one indiscretion couldn’t be enough to constitute such a long leave from the anchor chair,” the newsletter says. “Something else happened but the specifics from insiders on this point vary too much from person to person to be reported. One thing they all agree on, though. They all hear Griffith isn’t coming back, that the station is negotiating some sort of departure package since she apparently has three more years left on her contract.”
