"Donald Trump's alliance with Fox News has been one of the few constants throughout his shambolic presidency," Gabriel Sherman writes at Vanity Fair. "But in recent days, that bond has shown signs of fraying."

Sherman pointed to Trump's tweeted salvos at Fox News and some news anchors Sunday, but said those attacks have only "widened the chasm between the network's opinion hosts and the news division, which have been fighting a cold civil war since Roger Ailes was ousted in July 2016." One senior Fox staffer told Sherman, "Reporters are telling management that we're being defined by the worst people on our air," meaning pro-Trump opinion hosts like Sean Hannity, Jeanine Pirro, Lou Dobbs, and the Fox & Friends gang. An anchor close to Hannity gave the rebuttal: "We make all the money."

The final arbiter of this "cold civil war" will be Lachlan Murdoch, the eldest son of media baron Rupert Murdoch and the chairman and CEO of Fox Corp., the downsized media company created when Fox sold its entertainment assets to Disney. Lachlan Murdoch — "a libertarian conservative, not a MAGA diehard," Sherman notes — isn't expected to make any editorial changes until after that deal closes Wednesday, "for fear of antagonizing Trump into opposing it," Sherman reports, citing two sources close to Lachlan. And any changes from Murdoch are expected to be modest, at least at first.

But Hannity may not wait around. "Sources said Hannity is angry at the Murdochs' firing of Ailes and Bill Shine," believes "the Murdochs are out to get Trump," and may leave when his contract is up in 2021, Sherman reports. One source who heard the conversation said "Hannity told Trump last year that the Murdochs hate Trump, and Hannity is the only one holding Fox together."
