On Friday, Washington Post publisher and C.E.O. Will Lewis invited Patty Stonesifer, his predecessor and advisor, back to the paper’s headquarters on K Street to help manage the fallout from the turbulent leadership transition that he’d initiated on Sunday evening—a newsroom restructuring that effectively defenestrated executive editor Sally Buzbee, replacing her temporarily with former Wall Street Journal editor-in-chief Matt Murray, and longer term with The Telegraph’s Rob Winnett. Stonesifer, a longtime consigliere to the paper’s owner, Jeff Bezos, was just back in Washington following an Amazon board meeting in Seattle. And, while she still comes into the office on occasion, she presumably experienced a fair amount of P.T.S.D. roaming the building this time around.
