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.

Before today's first witness entered court, Trump attorney Chris Kise asked Judge Engoron to postpone today's proceedings after five members of the New York attorney general's team tested positive for COVID-19.

Describing the attorney general's conduct as "beyond irresponsible," Kise said that his team did not get adequate notice about the COVID exposures despite having close contact with positive individuals.

"Nothing else matters except for pursuing President Trump," Kise said. "We have the leading candidate for president of the United States in the courtroom today."

"The attorney general's office knew on Wednesday and didn't tell any of us," defense attorney Clifford Robert said. "We are truly in an outbreak."

Engoron declined to grant their requested delay.

In a statement, a spokesperson for New York Attorney General Letitia James said the state has complied with all CDC guidelines.

"Our office properly notified the court and defendants' counsel, and the court decided to proceed with trial today. If there were any concerns, defendants could wear masks today or at any point, but they have opted not to," the spokesperson said.

Trump called his former lawyer Michael Cohen a "proven liar" and "felon" as Trump entered the courtroom for his civil trial this morning.

"He's a felon, served a lot of time for lying, and we're just going to go in and see and I think you'll see that for yourself," Trump told reporters outside court.

Cohen pleaded guilty in 2018 to two separate criminal cases and eventually spent more than 13 months in prison -- but said that it was Trump who caused him to "follow a path of darkness."

Exiting his New York City apartment this morning, Michael Cohen told reporters he was "looking forward" to seeing Trump in court.

"It's been five years since we've been in the same room," Cohen said.

Cohen preemptively defended the credibility of his testimony and reiterated that he previously perjured himself "concert with and for the benefit of Donald J. Trump."

"My credibility should not be in question," Cohen said.

Former President Donald Trump must pay $354 million for fraudulent business practices, Judge Arthur Engoron has ruled.

Trump's sons Donald Trump Jr. and Eric Trump have been fined $4 million apiece, and former Trump Organization CFO Allen Weisselberg has been fined $1 million.

The decision bars Trump barred from serving as an officer of a New York company for three years, and bars his sons for two years apiece.

Regarding the dissolution of Trump's companies, the decision says, "This Court hereby modifies its September 26, 2023, Decision and Order solely to the extent of removing the language ordering the LLCs cancellation en masse. The restructuring and potential dissolution of any LLCs shall be subject to individual review by the Court appointed Independent Director of Compliance in consultation with Judge Jones."

In his decision, Engoron wrote that "Defendants' refusal to admit error -- indeed, to continue it, according to the Independent Monitor -- constrains this Court to conclude that they will engage in it going forward unless judicially restrained."

"Overall, Donald Trump rarely responded to the questions asked, and he frequently interjected long, irrelevant speeches on issues far beyond the scope of the trial," the judge wrote. "His refusal to answer the questions directly, or in some cases, at all, severely compromised his credibility."

"The accountants created these 'compilations' based on data submitted by the Trump entities," the decision said. "In order to borrow more and at lower rates, defendants submitted blatantly false financial data to the accountants, resulting in fraudulent financial statements. When confronted at trial with the statements, defendants' fact and expert witnesses simply denied reality, and defendants failed to accept responsibility or to impose internal controls to prevent future recurrences."

Of Donald Trump Jr., Engoron wrote, "Despite disclaiming responsibility for or knowledge of the Statements of Financial Conditions' contents, Trump, Jr. still insisted that the Statements of Financial Condition were 'materially accurate.'"

Engoron's decision follows an 11-week civil trial in New York, where Trump and three of his adult children testified.

New York Attorney General Letitia James sued Trump, his two adult sons, and Trump Organization executives in September 2022 for issuing fraudulent financial statements -- including over 200 false and misleading asset values between 2011 and 2021 -- to get better loan terms and business deals.
