Judge Arthur Engoron's attorney argues in a new court filing that the willingness of Donald Trump's followers "to engage in violence to show their support" for Trump justifies the limited gag order in the former president's civil fraud trial.

Trump filed an Article 78 proceeding against Engoron earlier this month to remove the gag orders the judge imposed prohibiting him from commenting on the judge's staff, but a panel of judges vacated a temporary stay of the gag orders last week.

"It is undisputed that Mr. Trump has an inordinate ability to draw attention, fervor, and animosity to those he singles out for attention. Whether he seeks it or not, some of Mr. Trump's followers are willing to engage in violence to show their support," said Engoron's attorney Michael Suidzinski, an assistant deputy counsel with the New York State Office of Court Administration.

Engoron's attorney questioned Trump's need to speak about the judge's staff during the trial or his campaign, adding that the gag order still permits him to criticize Engoron, the attorney general, the case itself, witnesses, and the entire judicial process.

"It is unclear, however, how his ability to talk about Justice Engoron's court staff is necessary for his campaign when this country faces a number of issues more worthy of debate," Suidzinski wrote.

"Given the real and demonstrated likelihood of harm that could come to Justice Engoron's court staff if the gag orders were annulled, Justice Engoron's legitimate and justifiable interest in preventing such harm greatly outweighs the de minimis interference to Mr. Trump's rights," Suidzinski wrote.

Court is not in session today after the defense yesterday called off the testimony of Eric Trump, who was scheduled to be today's lone witness.

Donald Trump's legal spokesperson, Alina Habba, said that testimony from Eric Trump was no longer needed because the court has heard sufficient testimony from defense experts and Deutsche Bank executives.

Eric Trump, who took the stand in the state's case last month, was scheduled to testify for the defense today -- but defense lawyers abruptly called off his testimony yesterday in order to streamline their case, defense attorney Clifford Robert said in court yesterday.

"Although Eric Trump was certainly prepared to testify again, his testimony is no longer necessary. He has already testified fully and well in the case," Habba said.

In a social media post Tuesday night, Donald Trump said he directed Eric not to testify.

"I told my wonderful son, Eric, not to testify tomorrow at the RIGGED TRIAL," Trump wrote.

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.

Prior to his brief cross-examination, real estate valuation expert Lawrence Moens quoted John Lennon's "Imagine" and compared Donald Trump to Martin Luther King Jr. at the conclusion of his direct testimony.

"You may say I am a dreamer, but I'm not the only one," Moens said, quoting the "Imagine" lyrics before comparing Trump to Thomas Jefferson and Martin Luther King Jr.

"He's a dreamer for sure. If you have a dream and are a great American, I don't think that's a bad thing," Moens said of Trump, whose Mar-a-Lago estate he praised as "something breathtaking" and "amazing to see."

Moens' cell phone went off during his testimony, and he briefly interrupted his direct examination to answer a call.

"I'll call you right back … love you," Moens said in a quiet tone as Judge Engoron watched in disbelief.

Moen apologized to the judge, explaining that the call was from his elderly father.

Court was adjourned for the day after Moens stepped off the witness stand.

Doug Larson's name appears across five years of Donald Trump's financial documents, according to records entered into evidence.

A longtime professional appraiser with the real estate firm Cushman & Wakefield, Larson was cited in Trump Organization documents as an expert at valuing properties like 40 Wall Street, Trump Tower, and an adjoining retail space called "Niketown." Spreadsheets entered as evidence explicitly reference multiple phone calls with Larson between 2013 and 2017.

When asked about these phone calls in court, Larson testified that no such conversations occurred.

"Is it fair to say that Mr. Trump valued Trump Tower at $526 million in conjunction with you?" state attorney Mark Ladov asked Larson.

"No, that is incorrect," Larson said.

"Were you aware that Mr. McConney was citing you as a valuation source in his work papers?" Ladov asked.

"No, I was not," replied Larson, who said he did not assist Trump Organization executives in valuing Trump Tower, Niketown, or 40 Wall Street, despite Trump's paperwork referencing him as a source.

Evidence presented by the state instead suggested that the valuations were determined using cherry-picked metrics from a generic email Larson sent clients.

"It's a way to get your name out to clients for potential work," Larson said about one such "email blast" that was used in a Trump Tower valuation.

Larson added that the valuations Trump Organization executives determined based on "consultation" with him used flawed methodologies, such as using capitalization rates related to office buildings to appraise the retail Niketown building.

"It doesn't make sense," Larson said about Niketown's $287 million valuation.

"It's inappropriate and inaccurate," Larson said about the Trump Organization relying on his name to support their valuations. "I should have been told, and appraisals should have been ordered."
