Former President Trump appears to be done watching his civil fraud trial, and he had a lot to say about it on his way out of the courthouse.

Speaking to reporters, Trump renewed his attacks on Judge Engoron and accused the "whole system" of being rigged against him while referencing the criminal charges he faces in Washington, D.C., and Fulton County, Georgia.

"Our whole system is corrupt. This is corrupt. Atlanta is corrupt, and what's coming out of DC is corrupt," Trump said.

Trump again claimed that his net worth is more than is represented in his financial documents, and said that his Mar-a-Lago estate is worth "50 to 100 times more" than what Engoron determined.

Trump also resumed attacks on the judge -- who he said is "run by the Democrats" -- and New York Attorney General Letitia James, who he alleged is communicating with the Department of Justice to "keep me nice and busy."

The former president said he's been "stuck" in court when he would rather be campaigning in early primary states.

Asked by ABC News why he attended the trial despite no obligation to do so, he claimed his attendance was necessary to expose corruption to the press.

"Why attend? Because they want to point it out to the press how corrupt it is, because nobody else seems to be able to do it," Trump said.

Trump departed the courthouse and is not expected to return to court for the afternoon session.

Judge Engoron lost patience with Trump's defense counsel during the cross-examination of longtime Trump accountant Donald Bender.

As defense attorney Jesus Suarez repeatedly asked Bender to recall how he arrived at specific values for specific assets in specific years, Engoron interrupted to ask how much longer the cross-examination would last.

Suarez said he would do his best to finish by the end of court today.

That prompted Kevin Wallace with the state attorney general's office to shout, incredulously, "Today?" Wallace accused Suarez of being overly performative with Trump seated at the defense table.

When Engoron reminded the defense, "Mr. Bender is not on trial here," Trump attorney Chris Kise interjected, "I would very much disagree with that."

The judge implored the defense to truncate the line of questioning.

"You're not allowed to waste time," Engoron said.

"This is insane," responded Trump attorney Alina Habba "He has not answered one question."

Engoron pounded the bench, asking reporters in the room to take note. "This is ridiculous," he barked.

Nearly 30 minutes after court resumed following a break, Trump entered the courtroom and returned to his seat at the counsel table.

The defense's cross examination of Mazars USA accountant Donald Bender continued after a brief interruption.

Court has resumed following a break, but Trump is notably absent from the courtroom. His paperwork remains at the counsel table, and his lawyers have left his seat empty.

Eric Trump and New York Attorney General Letitia James returned to the courtroom after the break, along with the lawyers for both sides.

Former Trump accountant Donald Bender is back on the stand for his cross-examination.

Judge Arthur Engoron denied Donald Trump's request for a mistrial, describing the defendants' arguments as "nonsensical," "disingenuous," and "utterly without merit."

Engoron rejected the motion without hearing any arguments from the New York Attorney General, who earlier this week requested that an extended briefing be scheduled.

"I cannot sign a proposed order to show cause that is utterly without merit, and upon which subsequent briefing would therefore be futile," Engoron wrote in his ruling.

Across a four-page order, Engoron sharply disagreed with the allegations from the defendants that he was engaging in "co-judging" with his law clerk.

"As I have made clear over the course of this trial, my rulings are mine, and mine alone. There is absolutely no 'co-judging' at play," Engoron said.

Addressing his principal law clerk's political donations, which the judge said she has largely made in order to purchase tickets to functions while pursuing elected judicial office, Engoron called out the defendants for failing to acknowledge the "applicable unambiguous ethical guidelines" that permit such donations. He similarly dismissed the idea that his clerk attending events sponsored by political organizations implies that she supports any position taken by those groups.

"Such arguments are nonsensical; and in any event, they are a red herring, as my Principal Law Clerk does not make rulings or issue orders -- I do," Engoron said in his ruling.

Court was subsequently adjourned for the day.
