From a post here last October:

“Attorney General” Bill Barr met with Rupert Murdoch last night; nobody knows what they talked about.

I’m sure it’s all very innocent. I’m sure Barr in no way tried to pressure Murdoch to make Fox even more slavishly adoring of Trump. I’m sure it’s entirely normal for an Attorney General to visit the boss of a notoriously political tv network, just to lift a few beers and shoot the shit.

The Guardian today:

The attorney general, William Barr, told Rupert Murdoch to “muzzle” Andrew Napolitano, a prominent Fox News personality who became a critic of Donald Trump, according to a new book about the rightwing TV network.

Barr’s meeting with Murdoch, at the media mogul’s New York home in October 2019, was widely reported at the time, with speculation surrounding its subject. According to Hoax: Donald Trump, Fox News and the Dangerous Distortion of Truth, by CNN media reporter Brian Stelter, subjects covered included media consolidation and criminal justice reform.

“But it was also about Judge Andrew Napolitano.”

The books will be published Tuesday.

Citing an unnamed source, Stelter writes that Trump “was so incensed by the judge’s TV broadcasts that he had implored Barr to send Rupert a message in person … about ‘muzzling the judge’. [Trump] wanted the nation’s top law enforcement official to convey just how atrocious Napolitano’s legal analysis had been.”

…

Though Barr’s words to Murdoch “carried a lot of weight”, Stelter writes, “no one was explicitly told to take Napolitano off the air”. Instead, Stelter reports, Napolitano found digital resources allocated elsewhere, saw a slot on a daytime show disappear, and was not included in coverage of the impeachment process.

There was no need to tell anyone explicitly to take Napolitano off the air, when there were so many more subtle options.
