Donald Trump, in an about-face on Sunday, announced he won’t be testifying in his own defense at the New York civil fraud trial that threatens his real estate empire.

“I have already testified to everything & have nothing more to say other than this is a complete & total election interference (Biden campaign!) witch hunt that will do nothing but keep businesses out of New York,” the former president — who was expected to be called to the stand by his attorneys on Monday — said in an all-caps post on his social media platform Truth Social.

“I will not be testifying on Monday,” he added in the two-part post.

Trump, 77, was set to testify again as one of the final witnesses in his defense case against New York Attorney General Letitia James’ claims that he exaggerated his worth by billions a year for better loan and insurance terms.

During heated testimony last month, after he was called to the stand by lawyers with the AG’s office, Trump and his team clashed multiple times with Manhattan Supreme Court Justice Arthur Engoron, who is deciding the non-jury case.

He also unexpectedly and briefly took the witness stand in October when Engoron wanted to question Trump about possible violations of the limited gag order barring him and his lawyers from talking about the judge’s court staff.

During that short stint on the stand, Trump denied that he was referring to Engoron’s chief law clerk Allison Greenfield when he said: “This judge is a very partisan judge with a person who is very partisan sitting alongside him.”

But the jurist said he didn’t buy Trump’s claims that he was actually referring to Michael Cohen — his former lawyer and “fixer” who was testifying at the time — and he fined the 45th president $10,000 on top of a previous $5,000 fine for violating his gag order.

Trump has attended eight days out of the 42 days of trial so far, though he is not required to be present in court like he would be in a criminal case.

His son Eric Trump had similarly been expected to take the stand again in the defense case after being called as a witness by the AG’s team, but also ended up not testifying as planned.

An expert witness called by Trump’s lawyers late last week — Eli Bartov, a professor of accounting at New York University —  is expected to wrap testimony on Tuesday.

Trump most recently attended trial Thursday to observe the testimony of Bartov, who told the court “there is no evidence whatsoever for any accounting fraud” and claimed James’ case has “no merit.”

Trump lauded the testimony as a win for his case, saying that “one of the greatest experts” and a “highly respected man” said he shouldn’t be found liable for fraud.

The 2024 Republican presidential frontrunner has taken nearly every opportunity in front of the media at court to attack Engoron, James and the trial claiming he’s a victim of a political witch hunt.

In a bombshell ruling from just before the start of the trial, Engoron found the former commander-in-chief liable on one of the main fraud claims by the AG’s office.

Trump has been in court eight days so far during the 42 days of trial.

Trump is facing claims by New York Attorney General Letitia James that he intentionally exaggerated his assets on financial documents for a decade for better loan terms. 

In that decision, he revoked the Trump Organization’s business licenses in the Empire state, but that has been put on hold until the trial concludes.

The AG will put on a brief rebuttal case following the conclusion of Bartov’s testimony.

Engoron is not expected to render his verdict in the case — which threatens the Trump real estate empire in the state — until late January.
