Going into the election, 19% of American voters called Fox News their primary news source, according to Pew Research. CNN was second, at 8%.
And after the election, in 2017, the White House briefing room placed Fox News' correspondent in the front row, sitting between CBS News and NBC News, which makes it difficult hard to argue that it wasn't mainstream.
Nicole Hemmer, an assistant professor of Presidential studies at the University of Virginia's Miller Center, told The New Yorker it was the closest America has come to having state TV.
While Jane Mayer, who wrote The New Yorker piece, showed in an investigation that while it wasn't state television, Fox News was increasingly pulling Trump challengers from the airwaves.
The comparison wasn't helped with anchor Sean Hannity. At one point, he was reportedly speaking to Trump every night, keeping communications open, and their connection close. Hannity also speak on his behalf at a campaign rally, and the Washington Post called Hannity the deputy chief of staff.
