Donald Trump's former lawyer and self-described "fixer" is scheduled as the second witness to testify today at the trial.

Bill Kelly, a lawyer at Trump's former accounting firm, Mazars USA, is set to begin his testimony this morning.

Mazars issued Trump's statements of financial condition before severing its business relationship with the Trump Organization last year and withdrawing the statements issued between 2011 and 2020.

"We have come to this conclusion based, in part, upon the filings made by the New York Attorney General on January 18, 2022, our own investigation, and information received from internal and external sources," Kelly wrote in a 2022 letter to the Trump Organization.

Trump defense lawyers Chris Kise, Clifford Robert, and Michael Farina have appealed Judge Arthur Engoron's decision to sanction and fine them for making frivolous arguments during pretrial arguments.

On the eve of trial, Engoron sanctioned the attorneys for their "continued reliance on bogus arguments," and ordered each to pay a $7,500 fine.

"Sanctions are the only way to impress upon defendants' attorneys the consequences of engaging in repetitive, frivolous motion practice after this Court," Engoron wrote in his decision at the time.

In their filing, the lawyers have asked an appeals court to determine if Engoron "committed errors of law and/or fact, abused its discretion, and/or acted in excess of its jurisdiction."

Former President Trump's civil fraud trial is adjourned until Tuesday due to COVID-19 exposures, the New York attorney general's office has announced.

Officials did not say who had been exposed or when.

Trump attended the trial on Tuesday and Wednesday of last week and said on Wednesday that he could return to court for the testimony of his former attorney Michael Cohen, which could begin tomorrow.

The trial is scheduled to continue tomorrow morning with testimony from a lawyer at Trump's former accounting firm, Mazars USA, followed by Cohen.

Week Three of the trial concluded on Friday with Judge Engoron fining Trump $5,000 for violating a gag order the judge had issued prohibiting social media posts and statements about the judge's staff.

While Engoron found that Trump's violation was "inadvertent," he threatened additional fines or possibly even jail time if Trump violated the order again.

Judge Engoron has fined Donald Trump $5,000 for what the judge called Trump's "inadvertent" violation of his limited gag order that occurred when the former president's false Truth Social post about Engoron's clerk was not removed from Trump's campaign website.

"Donald Trump has received ample warning from this Court as to the possible repercussions of violating the gag order," Engoron wrote in a ruling after court had ended for the day. "He specifically acknowledged that he understood and would abide by it. Accordingly, issuing yet another warning is no longer appropriate; this Court is way beyond the 'warning' stage."

The judge said he decided to impose a nominal $5,000 fine "given defendant's position that the violation was inadvertent."

However, the judge wrote, "Make no mistake: future violations, whether intentional or unintentional, will subject the violator to far more severe sanctions, which may include, but are not limited to, steeper financial penalties, holding Donald Trump in contempt of court, and possibly imprisoning him pursuant to New York Judiciary Law 753."

Former President Donald Trump's plan to deliver part of his closing argument Thursday, as reported yesterday by ABC News, is now in doubt after he failed to meet a deadline to agree to limitations imposed by Judge Arthur Engoron.

According an email exchange between Engonon and defense counsel that was posted to the public docket Wednesday, Engoron said that Trump would have to follow the case's limited gag order, and that he would not be allowed to "impugn" the New York attorney general or her staff -- limitations that Trump attorney Chris Kise rejected, calling them "untenable."

"The limitations I am imposing, in my absolute discretion, are not subject to further debate. Take it or leave it," Engoron replied on Jan. 9, according to the email thread.

When Trump's lawyers missed the first deadline set by Engoron, the judge determined that Trump could not testify. Kise then responded that he did not see the deadline and requested that the closing arguments be postponed because of the death of Melania Trump's mother on Tuesday.

"I am sad to advise the Court that Mrs. Trump's mother passed away this evening. Because of the challenges presented by this deeply personal family matter, President Trump has asked that I request the Court postpone the date for closing argument," Kise wrote yesterday.

Engoron promptly denied the request and said the closings would continue as planned.

"On balance, going forward makes the most sense. Please tell Mr. Trump that I am sorry," Engoron wrote.

Kise informed Engoron that Trump still planned to attend the closings and speak.

"Despite the fact that his Mother-in Law, who he was very close to, passed away late last night, President Trump will be speaking tomorrow," Kise said in an email this morning.

When Engoron asked for assurance that Trump agreed to his rules, Kise pushed back, writing, "You are not allowing President Trump, who has been wrongfully demeaned and belittled by an out of control, politically motivated Attorney General, to speak about the things that must be spoken about."

"I won't debate this yet again. Take it or leave it. Now or never. You have until noon, seven minutes from now. I WILL NOT GRANT ANY FURTHER EXTENSIONS," Engoron replied at 11:54 a.m.

After Kise failed to respond, Engoron emailed him at 12:12 p.m. that he assumed Trump would not be speaking and that their email exchange would be posted to the court's public docket.

Responding to the development, Trump's legal spokesperson, Alina Habba, said in a statement to ABC News: "Is anyone surprised anymore?"
