Donald Trump has made no secret of his great admiration for Fox News—he tweets praise of it constantly—and his disdain for other, “fake news” outlets, which he regards as “enemies of the people.” But the closeness between Fox News and the White House is unprecedented in modern times, Jane Mayer tells David Remnick. In a recent article, Mayer, a staff writer since 1995, analyzes a symbiotic relationship that boosts both Trump’s poll numbers and Rupert Murdoch’s bottom line. “I was trying to figure out who sets the tune that everybody plays during the course of the day,” Mayer says. “If the news on Fox is all about some kind of caravan of immigrants supposedly invading America, whose idea is that? It turns out that it is this continual feedback loop.” Mayer pays particular attention to the role of Bill Shine, the former Fox News co-president and now former White House deputy chief of staff for communications. Shine resigned days after Mayer spoke to Remnick. In his tenure in the Administration, Shine helped create a revolving door through which those who craft the Administration’s political messaging and those who broadcast it regularly trade places. She also discovered that Shine was linked to the network’s practice of intimidating employees who alleged sexual harassment at work.
