Dump Arthur? Insiders at The New York Times are speculating that the fallout from the Judy Miller imbroglio will prove fatal to Times Co. CEO Arthur Sulzberger Jr. He presided over the paper's staunch defense - and then searing criticism - of his longtime friend Miller, the controversial Plamegate figure who went to jail rather than reveal her source, vice presidential aide Scooter Libby, only to strike a deal with the special prosecutor to testify about her dealings with Libby in return for her freedom. Vanity Fair writer Seth Mnookin - whose story Miller tried to have killed - notes that the buzz in The Times newsroom is that "if Judy is the new Jayson [Blair], then Arthur is the new Howell" Raines, the executive editor who lost his job amid the Blair scandal. A Times editor tells Mnookin: "I feel it's inevitable that Arthur's going to go, as I felt it was that Howell was going to go." Of course, that's up to Sulzberger's relatives, who control the Class B voting stock.
