The liars at Fox News are trying to provide cover for Trump to fire Mueller.

[I]n Fox’s alternate universe, the investigation is “illegitimate and corrupt,” or so says Gregg Jarrett, a legal analyst who appears regularly on Mr. Hannity’s nightly exercise in presidential ego-stroking. “Mueller’s stooges literally are doing everything within their power, and then some, to try and remove President Trump from office,” Mr. Hannity said last Wednesday.

“What a total travesty! They should all step aside,” Ms. Ingraham said last week, almost gleefully, about the supposed conflicts of interest permeating the special counsel’s highly experienced team of investigators. “Including Bob Mueller.”

How do they manage to convince themselves that of the two parties involved, Mueller is the corrupt and dishonest one? Trump’s squalid history is on the record for anyone to see. Republican is one thing, and rooting for corruption and fraud and lying and cheating is another. Just check out Richard Painter on Twitter to see that.

Perhaps the most inflammatory rhetoric has come from Ms. Pirro, the host of “Justice With Judge Jeanine” and a “presidential favorite,” according to The Times. “There is a cleansing needed in our F.B.I. and Department of Justice,” Ms. Pirro said Saturday, in her most unhinged rant yet. “It needs to be cleansed of individuals who should not just be fired but who need to be taken out in handcuffs.”

Ms. Pirro named, among others, James Comey, the former F.B.I. director (“so political, so corrupt”); Andrew McCabe, the bureau’s deputy director, apparently in the tank for Hillary Clinton; and Peter Strzok, a top counterintelligence agent whom Mr. Mueller removed from the investigation after learning of private text messages he sent in 2016 criticizing Mr. Trump and praising Mrs. Clinton.

Topping her list of outlaws was, of course, Mr. Mueller, who she said “can’t come up with one piece of evidence!” Maybe she just forgot about the indictments and guilty pleas? Ms. Pirro, a former New York prosecutor and judge, didn’t allege any actual crimes, just that Mr. Mueller and his people are guilty of “attempting to destroy Trump.”

It would be one thing if Ms. Pirro were only spouting off on television. But she is a friend of Mr. Trump’s and has met privately with him and his top advisers to sell her half-cocked theories. After Mr. Trump’s victory last year, she interviewed to be his deputy attorney general, a job that would have empowered her to fire Mr. Mueller on her own.

To put it mildly, this is insane. The primary purpose of Mr. Mueller’s investigation is not to take down Mr. Trump. It’s to protect America’s national security and the integrity of its elections by determining whether a presidential campaign conspired with a foreign adversary to influence the 2016 election — a proposition that grows more plausible every day.

If only the adults could take over from the tantrumming children.
