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.

Former President Trump has confirmed he plans to testify as a defense witness on Monday.

"I will be testifying on Monday," Trump wrote on his social media platform.

Court is not in session today, but Trump is expected to be in attendance tomorrow.

Trump's plan to testify was thrown into question on Tuesday after Judge Arthur Engoron denied a request from the defense to delay the testimony to accommodate Trump's effort to appeal the limited gag order in the case that prohibits him from commenting on the judge's staff.

"He is not capable of fully testifying because he is subject to the gag order," Kise said, arguing for a delay.

"Absolutely not. No way, no how. It's a nonstarter," Engoron said in response to the defense's request for a delay. "If he is going to testify, it'll be Monday, and that's that."

While Trump's lawyers have attempted to appeal the limited gag order to a higher court, their application to expedite the appeal was denied on Monday, ensuring that the limited gag order will be in place when Trump testifies.

During a campaign stop in Iowa, Trump repeated his claims that his opponents are trying to silence him, describing the gag order as an "honor."

"In many ways, it's an honor because if they wanted to hear me speak, they wouldn't do the gag order," Trump said.

When asked if he's concerned about his scheduled court testimony, Trump said "No, not at all."

Trump is set to be the final witness for the defense case when he testifies on Monday.
