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.

Testifying for the defense, former President Trump's eldest son described his father as a real estate "visionary" who "sees the sexiness in a real estate project," creating value for the family business that cannot be captured on paper.

Donald Trump Jr. began his testimony with a quip after Judge Engoron welcomed him back to the stand following his testimony earlier in the month.

"I'd say it's good to be here, but the attorney general would probably sue me for perjury," Trump Jr. joked.

In his testimony, Trump Jr. described the Trump Organization as "a large family business," with Trump and his eldest children at the top and other executives handling many of the details.

"If there were numbers and things, I would rely on them to give me that," Trump Jr. said.

He recounted the history of the Trump Organization, beginning with his great-grandfather who he said built hotels in the Yukon Territories of Canada. His grandfather, Fred Trump, "started working on job sites around Queens, learned the trades" and eventually "created an incredible portfolio, by the time of his passing, of rental apartments in Brooklyn and Queens."

A state attorney jokingly objected that references to the 1800s were outside the statute of limitations -- then more seriously objected to the history lesson's relevance.

"I think it is relevant to get the historical perspective -- I find it interesting," Judge Engoron said in overruling the objection. "Let him go ahead and say how great the Trump Organization is."

Trump Jr. obliged.

"My father learned a lot of the business from him, but had some flair and saw New York City and Manhattan as the ultimate frontier," he said. Speaking of Trump Tower, he said, "I think it would have been one of the first, I think great, ultra-luxury real estate emerging in Manhattan."
