The former Veep showrunner, who is a director and executive producer on the five-part Watergate limited series, was investigated for allegedly threatening a prop master using the F-word and saying he will never work again, according to Deadline. "Mandel and The White House Plumbers‘ prop staff, including the prop master involved in the verbal altercation, are all back at work and remain on the show, sources said," reports Deadline's Nellie Andreeva. "As a result of the investigation, HBO has put additional protocols in place for the remainder of the shoot, including HR representatives on set, I hear."
