Former President Donald Trump showed up at a lower Manhattan courthouse on Thursday morning to sit in on the civil fraud trial that threatens his real estate empire.

Trump, 77, is set to remain at Manhattan Supreme Court at least until the lunch break to observe as his defense attorneys question one of their final witnesses.

The 2024 GOP presidential frontrunner has said he’ll return to court on Monday to close out the defense case with his own testimony.

Trump hasn’t attended the trial since Nov. 6, when he testified as the last witness in New York Attorney General Letitia James’ $250 million fraud case against him.

The 45th president has attended seven of the 40 days of the proceedings so far, and is not required to be present in court like he would be in a criminal case.

He’s taken nearly every opportunity in front of media cameras at the courthouse to attack the AG and Justice Arthur Engoron — who is deciding the non-jury trial.

But on Thursday and Monday, the real estate tycoon won’t be allowed to go after Engoron’s chief law clerk Allison Greenfield since a limited gag order, barring Trump and his lawyers from speaking about the judge’s staff, was reinstated last week by an appeals court.

Trump — who has repeatedly claimed that Greenfield is co-judging alongside Engoron — is seeking to bring the appeal to the highest court in the state.

He has argued that the gag order is a violation of his right to free speech, which he says is all the more important as he’s on the campaign trail.

The issue likely won’t be resolved before he’s done testifying.

James filed suit last year against Trump, his two eldest sons, Ivanka, the family real estate company and others claiming that Trump exaggerated his net worth by billions a year on yearly financial statements in order to get an edge on loan and insurance applications.

Trump has denied the AG’s allegations and repeatedly claimed that he’s the victim of a political witch hunt.

Ivanka, 42, was dismissed as a defendant from the case earlier this year when an appeals court found that the claims against her fell outside of the statute of limitations.

All four Trumps testified when called by the AG as witnesses, and Don Jr., 45, also testified a second time as part of the defense case.

The family members testified that they weren’t involved in Trump’s annual statements of financial condition, on which the AG claims Trump lied about his assets from 2011 to 2021. Instead, they have blamed accountants and lawyers for any errors on the forms.
