Now, it appears both sides want peace. This morning, Trump tweeted that Ailes called to assure him that Fox will cover him “fairly” going forward. According to two high-level Fox sources, Ailes’s diplomacy was the result of increasing concern inside Fox News that Trump could damage the network. Immediately following Thursday’s debate, Fox was deluged with pro-Trump emails. The chatter on Twitter was equally in Trump’s favor. “In the beginning, virtually 100 percent of the emails were against Megyn Kelly,” one Fox source, who was briefed on the situation, told me. “Roger was not happy. Most of the Fox viewers were taking Trump’s side.” 

Things got worse for Ailes over the weekend. In a phone conversation, Trump told Sean Hannity that “he was never doing Fox again,” according to one person with knowledge of the call. The anti-Kelly emails, and threat of a boycott by Trump, seem to have pushed Ailes to diffuse the war. One Fox personality told me that Fox producers gave instructions to tell in-house talent not to bring up Trump’s controversial comments that Kelly had “blood coming out of her wherever” during the debate. According to one count, Fox only aired Trump’s comment once since Friday, while CNN mentioned it at least 50 times.

In recent days, Ailes got a glimpse of what a Trump-less Fox News would look like.
