On Tuesday at 5 p.m., Bari Weiss, CBS News president Tom Cibrowski, and newbie 60 Minutes executive producer Nick Bilton summoned Scott Pelley to a meeting in Tom’s office on the executive floor at West 57th Street. A day earlier, in Nick’s first 60 Minutes staff meeting, Scott had taken his new boss to task over his “slender qualifications,” pressed him to explain why several of the show’s top producers and correspondents had recently been fired, and accused Bari of “murdering” the storied newsmagazine. In many professions, of course, such open defiance might have been grounds for immediate termination. The journalism business, which is built on gilded talent contracts, professional (and often performative) interrogation, institutional egos, and an enduring mythology around the truth, has long afforded its marquee stars a wider berth for insubordination.
