Vanity Fair's Gabriel Sherman reports President Trump is worried Fox News is "going rogue" ahead of the presidential election. A source tells Sherman that earlier this summer, Trump screamed at Murdoch during a phone call. “They had a humongous blowup. Trump yelled that Fox’s coverage is unfair and the polling is fake,” the source said. “Rupert defended the network’s standards and polling.” Meanwhile, Sherman reports that the Trump campaign had hoped Fox News' Bret Baier or Martha MacCallum would moderate a debate instead of Wallace. "Sources close to Trump are worried that Trump is unprepared to handle what Wallace could throw at him," reports Sherman. "The two have history. In July, Wallace’s contentious interview with Trump featured the president boasting that he passed a cognitive test...Wallace is deeply unpopular with pro-Trump hosts at Fox."
