Journalist Gabriel Sherman talks to Peter Kafka about his biography of Fox News' Roger Ailes, which has just been made into a Showtime series with Russell Crowe. He talks about how he wrote the book despite Ailes' pushback and intimidation tactics. Also: how Ailes built up Fox News, and how he might react to the network's relationship to the Trump Whitehouse if he were still alive today. And ...  on working (or not) with Russell Crowe on the set of 'The Loudest Voice in the Room.'
