Try this at home: The next time there's a big breaking news story about special counsel Robert Mueller's Russia probe, or a report about anything political other than the Southern border or Trump's national security executive order, make yourself flip news channels for a few minutes among CNN, MSNBC and Fox News.

If the subject on CNN and MSNBC or NBC or CBS or ABC is Russia related, Fox likely will be talking border fear or the latest Democratic freshman so-called outrage. If CNN or the other station highlights are about the border or executive order, Fox will probably be reliving Donald Trump's greatest campaign trail hits.

This could become your new BFF TV game. But one thing's for sure: It should, no will, make you rethink Fox's favorite self-promotion line: "Most trusted news." More accurate promo lines would be Trump Propaganda TV. Or RT-TV [formerly called Russia Today TV] U.S.

The New Yorker's investigative reporter Jane Mayer posted an in-depth report earlier this week headlined, "The making of the Fox News White House," which examines whether Fox has made a clean break with partisan reporting and become simply propaganda. It's the best assembly of the many examples of this posit we've seen.

Here are some highlights:

* A motorcade in January to a Texas border town with press corps in tow (a Trump government-shutdown diversionary trick), was met by Fox News host Sean Hannity. Hannity, already on location and unconfined by the Secret Service, was mingling with administration officials and huddling with the White House communications director (and ex-Fox official) Bill Shine. Hannity even hugged Homeland Security Secretary Kirstjen Nielsen. At the dog-and-pony-show's end, Trump gave Hannity an exclusive on-air interview.

Politico later reported that it was Hannity's seventh interview with the president, and Fox's 42nd. Since then, Trump has given Fox two more. He has granted only 10 to the three other main television networks combined, and none to CNN, which he denounces as "fake news."

* In the past two years Fox watchers and alumni say the network has "evolved into something that hasn't existed before in the United States." Nicole Hemmer, an assistant professor of presidential studies at the University of Virginia's Miller Center and the author of "Messengers of the Right," a history of the conservative media's impact on American politics, told Mayer: "It's the closest we've come to having state TV."

Hemmer argues that Fox, as the most-watched cable news network, acts as a force multiplier for Trump, solidifying his hold over the Republican Party and intensifying his support. "Fox is not just taking the temperature of the base — it's raising the temperature," she told Mayer. "It's a radicalization model." For both Trump and Fox, "fear is a business strategy — it keeps people watching."

And Mayer writes: "As the President has been beset by scandals, congressional hearings, and even talk of impeachment, Fox has been both his shield and his sword. The White House and Fox interact so seamlessly that it can be hard to determine, during a particular news cycle, which one is following the other's lead."

* Bill Shine is but the most recent Fox News alum to join Trump's administration. There's also former Fox contributor Ben Carson, former Fox commentator John Bolton, and former Fox News anchor Heather Nauert. Until she resigned, there was former Fox commentator K.T. McFarland. Kimberly Guilfoyle, a former Fox co-host, now works on Trump's reelection campaign and dates Donald Trump Jr.

* Fox insiders and a source close to Trump believe that the late and former Fox CEO Roger Ailes informed the Trump campaign about Megyn Kelly's "You've-called-women-fat-pigs" question. And in the fall of 2016, as the election neared, FoxNews.com reporter Diana Falzone, who covered the entertainment industry, obtained proof that Trump had engaged in a sexual relationship in 2006 with a porn star — Stormy Daniels. The story didn't run. The head of FoxNews.com told her [and another employee overheard it], "Good reporting, kiddo. But Rupert [Murdoch, Fox owner] wants Donald Trump to win. So just let it go."

* Reed Hundt, a former Federal Communications Commission chairman, told Mayer "there have been three moves that have taken place in the regulatory and antitrust world" involving telecommunications "that are extremely unusual, and the only way to explain them is that they're pro-Fox, pro-Fox, and pro-Fox."

Last June, the Trump administration approved Fox's bid to sell most of its entertainment assets to Disney for $71 billion dollars. The Murdoch family will receive more than $2 billion dollars in the deal. The Justice Department expressed no serious antitrust concerns even though the combined company will reportedly account for half the box-office revenue in America.

In July, the FCC blocked Sinclair Broadcast Group, a conservative rival to Fox, from combining with the Tribune Media Company, arguing the deal would violate limits on the number of TV stations one entity can own and upending Sinclair's hope of becoming the next Fox.

Meanwhile, the Justice Department went to court in an effort to stop AT&T's acquisition of Time Warner, which owns CNN. Murdoch — and Trump — opposed the deal.

So what do you think Trump-RT-TV will do with the Mueller probe findings?
