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."

Testifying about the preparation of the Trump Organization's statements of financial condition in 2011, former Mazars USA accountant Donald Bender said Trump executives largely provided the input data for statements, in addition to dictating the standards by which the work was completed.

"We would cut and paste that information into a new worksheet," Bender said about the approach taken by Mazar after receiving new data from co-defendant Jeffrey McConney of the Trump Organization.

When asked about the compliance with the Generally Accepted Accounting Principles -- which Bender testified are the standards for accounting in the United States -- Bender repeatedly placed responsibility in the lap of the Trump organization.

"That was the Trump Organization's responsibility," Bender testified about GAAP compliance.

Bender acknowledged that he rarely questioned the inputs from the Trump Organization, and when he did, he largely dealt with McConney and executives other than Trump and his adult sons.

Repeatedly asked by the state attorney if Mazars would have issued the statements if they had known the Trump Organization included material misrepresentations in their data, Bender reiterated that Mazars would not have issued the statements.

When Judge Engoron remarked at the end of the trial day that the state would still need to present further evidence to prove that the 2011 statement was within the statute of limitations, Trump seized the statement as a partial victory.

"The last five minutes was outstanding, because the judge actually conceded that the statute of limitations … is in effect," Trump told reporters as he was leaving court.

Engoron, however, did not completely rule out the 2011 evidence during trial, instead appearing to remind counsel that they need to show the 2011 statement represents an ongoing concern that falls within the statute of limitations.

Testimony is scheduled to resume on Tuesday at 10 a.m. ET.
