Judge Andrew Napolitano appeared on "Outnumbered Overtime" to weigh in on several developments related to Special Counsel Robert Mueller's investigation, including conservative author Jerome Corsi filing a “criminal and ethics complaint” against Special Counsel Robert Mueller’s team, accusing investigators of trying to bully him into giving “false testimony” against President Trump.

The complaint, which Corsi had threatened for days, is the latest escalation between Mueller’s team and its targets.

The 78-page document, asserting the existence of a “slow-motion coup against the president,” was filed to a range of top law enforcement officials including Acting Attorney General Matthew Whitaker, DOJ Inspector General Michael Horowitz, D.C.’s U.S. Attorney Jessie Liu and the Bar Disciplinary Counsel.

Corsi, who is connected with political operative Roger Stone, has claimed for the past week that he was being improperly pressured by Mueller’s team to strike a plea deal which he now says he won’t sign.

"Almost everything that he has accused the prosecutors of is standard operating procedure for prosecutors," Napolitano said, calling these tactics "the dark side of law enforcement."

"Prosecutors can coerce, they can threaten, they can lie, they can deceive, they can do anything short of actually committing a crime in order to extract evidence from a witness or in order to flip the witness to their side," Napolitano explained. "And that's apparently what they've tried to do with Jerry Corsi."

As for Trump attorney Rudy Giuliani questioning Mueller's tactics and calling probe unethical, Napolitano said that's what a lawyer representing the president should do.

"He's been very effective at persuading the public that the indictment or impeachment of Donald Trump is untenable. That doesn't persuade a judge or a jury, but that does persuade the public. And that's what Rudy's been spending his time doing," Napolitano said.

He added that Giuliani, a former federal prosecutor himself, knows that the techniques he's blasting are the same techniques he used.

"That's the value that he brings to the president. He knows how the government operates."
