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 Engoron has denied a motion from the New York attorney general to preclude four expert witnesses from testifying for the defense when the defense presents it case starting on Monday.

The state had sought to preclude the four experts' testimony on the grounds that, following the testimony of the state's witnesses, the four defense witnesses were no longer relevant to the case.

"You've won the battle. We'll see if you win the war," Engoron told defense attorney Chris Kise -- though he warned Kise that he would cut off the witnesses if they try to debate facts already established in the case.

In making his ruling, Engoron reiterated his finding from his earlier summary judgment order that Donald Trump made at least ten internally contradictory claims in his statements of financial condition.

"You can't have a correct statement with these kinds of errors," Engoron said.

Kise told the court that Donald Trump Jr. will be the first witness to testify in the defense's case on Monday.

"Oh, I know him," Engoron deadpanned after the announcement.

It will mark Trump Jr.'s return to the witness box after the state put him on the stand last week.
