Former Trump attorney Michael Cohen has begun his testimony in his former boss' civil fraud trial.

Sitting at a cramped counsel table between his lawyers, Trump is about ten feet from his former lawyer and so-called "fixer."

The courtroom itself is at capacity, with attendance appearing to exceed the number of observers during the trial's opening statements.

When Mazars USA said that Trump's financial statements were no longer reliable in 2022, the accounting firm did not conduct an audit or identify any "material discrepancies" in Trump's statements, Mazars General Counsel Bill Kelly testified.

"As we have stated in the Statements of Financial Condition, Mazars performed its work in accordance with professional standards. A subsequent review of those workpapers confirms this," Kelly wrote in a 2022 letter to the Trump Organization entered into evidence.

Both Trump and his lawyer Jesus Suarez seized on the admission from Mazars.

During cross examination, Suarez displayed multiple financial statements and repeatedly asked Kelly about the lack of discrepancies identified in the statements. Exiting court for a break, Trump also focused on that portion of the testimony.

"They found no discrepancies, there was nothing wrong with the financials," Trump said, alleging that his former accountants were "abused" and "hurt very badly" by the New York attorney general.

Trump's accounting firm resigned from engagements with the Trump Organization in 2021 after learning it could no longer rely on former CFO Allen Weisselberg, Mazars USA General Counsel Bill Kelly testified.

The next year, Mazars determined that Trump's statements could no longer be relied upon following a filing related to New York Attorney General Letitia James' investigation of the Trump Organization.

"When the NYAG filed a paper in court, you took them at their word and never once conferred with your client?" defense attorney Jesus Suarez asked during his cross examination of Kelly, adding that Trump paid Mazars millions before their relationship ended.

"You just kicked them to the curb, right?" Suarez added, alleging that Mazars tried to "curry favor" to avoid legal problems with authorities.

"We did not kick them to the curb," Kelly responded.

The cross examination of Kelly appeared to test the patience of Judge Engoron, who interrupted the questioning twice.

"That has been asked about five times already," Engoron said at one point. At a later point, he added, "Asked and answered many times. Yes, they were paid."

Trump lawyer Chris Kise continued to spar with state attorney Louis Solomon during the testimony of Mazars General Counsel Bill Kelly.

After Solomon objected to a question posted in Kelly's cross-examination, Kise interjected to call out Solomon for being hypocritical about the bounds of acceptable testimony.

"Everything in this courtroom concerns me and my client, including your health," Kise said, referring back to his earlier concern about a courtroom COVID-19 outbreak.

"Thanks for your concern," Solomon responded offhandedly.

Trump and his attorneys have adjusted their seating compared to past days, possibly due to health concerns, so that Trump and Kise are sitting further from the state attorneys.

As court resumed after the lunch break, Judge Engoron admonished Donald Trump for a post he made this afternoon on his Truth Social platform regarding Engoron's clerk, Alison Greenfield.

"Personal attacks on members of my court staff are unacceptable and inappropriate. Consider this statement a gag order forbidding all parties from posting, emailing or speaking publicly about any of my staff," the judge said in his admonishment.

The post, which included a photo of Greenfield with Senate Majority Leader Chuck Schumer, made unsubstantiated claims about her connections with Schumer and falsely claimed that Greenfield is "running" the case against Trump.

Trump apparently made the post, which linked to Greenfield's Instagram account, while the former president was sitting in the courtroom.

The post was deleted shortly before the judge's admonishment, but it was up for at least an hour and a half. Engoron lamented that the sentiment was shared to millions.

The judge did not mention Trump by name but noted the post came from one of the defendants.

Greenfield sits at the bench to Engoron's immediate right and the judge is often seen conferring with her over legal and logistical matters.

In a statement, Schumer spokesperson Allison Biasotti called Trump's post "ridiculous, absurd, and false," saying that "Sen. Schumer does not know Ms. Greenfield. As is well known, Sen. Schumer attends countless events in every corner of the state where tens of thousands of constituents take photos with him, just like this one, which was taken at a stop at an annual brunch in Manhattan.”
