Anthony Scaramucci’s alma mater postponed an event featuring the flamed-out White House communications chief after he threatened to sue a student and the school paper over a critical op-ed piece, according to a report.

The Mooch, who earned an undergraduate degree in economics at Tufts University, was scheduled to speak Monday at the school’s Fletcher School of Law and Diplomacy, where he has served on an advisory board since 2016, the Boston Globe reported.

Earlier this month, 26-year-old graduate student Camilo Caballero wrote a piece in the Tufts Daily criticizing Scaramucci’s position on the board — referring to him as a “man who makes his Twitter accessible to friends interested in giving comfort to Holocaust deniers” and stating that Scaramucci “sold his soul in contradiction to his own purported beliefs” for a White House position.

Scaramucci, whose “media venture” ran a Twitter poll asking how many Jews were killed in the Holocaust, told Caballero in an email that he had “suggested publicly” that Scaramucci had engaged in unethical behavior.

“So either back it up or you will hear from my lawyer,” Scaramucci wrote Nov. 16. “You may have a difference of opinion from me politically which I respect but you can’t make spurious claims about my reputation and integrity.”

His attorney then threatened legal action unless Caballero and the newspaper retracted the “false and defamatory allegations of fact” and issued an apology, according to the Globe.

Caballero said the former Trump administration official was trying to prevent him from exercising his First Amendment rights.

“He is someone that uses his money to gain power and his wealth to buy himself into things that will get him attention. And he uses this power as a scare tactic … to get people to not exercise their First Amendment rights,” Caballero said. “He’s trying to stop me from exercising my First Amendment right, and that’s plain wrong.”

More than 240 students and administrators have signed an online petition calling for Scaramucci’s removal from the advisory board.

But in an interview Sunday night, Scaramucci denied he was trampling on students’ free speech, saying he will defend himself against an “attack” that he described as factually inaccurate, the Globe reported.

“I’m shocked that a university that I love and have been a part of for 35 years is silencing that debate because of my request for an apology,” he said.

Tufts spokesman Patrick Collins told the Globe that the Monday session would have addressed Scaramucci’s “background, experience and the petition calling for his removal” from the Fletcher board, but it was postponed until these “legal matters” are resolved.

“We’re disappointed that Mr. Scaramucci has taken this action,” Collins said in a statement.

The Tufts Daily’s editor in chief, Gil Jacobson, 21, said the paper would run Scaramucci’s letter demanding a retraction and an apology in Monday’s print edition.

Scaramucci was booted in July after serving 10 days as President Trump’s spokesman, after a New Yorker writer recorded him using vulgar language during an interview.

During a trip to Israel last week, he said he expected to return to politics and help Trump win another term.
