You could argue Donald Trump became president largely thanks to Fox News creator Roger Ailes. But Ailes resigned as chairman and CEO after a series of sexual harassment allegations. Less than a year later, in May 2017, he died. Now there’s a new documentary about Ailes, called “Divide and Conquer: The Story of Roger Ailes.” It’s in select theaters December 7th, and on demand on iTunes, Amazon, and Hulu.
