More breaking news from press tour: NBC chief Jeff Zucker announced that Donald Trump has inked a deal to preside over two more cycles of The Apprentice next season. And what about buzz that Martha Stewart would also be playing some sort of role on the show? Zucker's nonanswer spoke volumes. "We're not prepared to talk about that at this time," he said. Meanwhile, Zucker scored the zinger of the week when responding to a question about his rival Les Moonves' rumored pursuit of Kate Couric to replace Dan Rather on the CBS Evening News. Quipped Zucker: "If CBS goes after Katie Couric, we're going after [Moonves' wife and Early Show cohost] Julie Chen."
