Judge Arthur Engoron is requesting more information about potential perjury committed by defendant Allen Weisselberg, the former Trump Organization CFO, according to an email shared on the court's docket.

As ABC News has reported, Weisselberg is in plea talks with the Manhattan district attorney's office to resolve a potential perjury charge, according to sources familiar with the matter.

"As the presiding magistrate, the trier of fact, and the judge of credibility, I of course want to know whether Mr. Weisselberg is now changing his tune, and whether he is admitting he lied under oath in my courtroom at this trial," Engoron wrote in an email he sent to the parties on Monday.

Engoron requested both parties to send him a letter by Wednesday at 5 p.m. ET detailing "anything you know about this that would not violate any of your professional ethics or obligations."

"I would also appreciate knowing how you think I should address this matter, if at all, including the timing of the final decision," Engoron added.

The judge is still weighing his decision in the $370 million fraud case, which he originally indicated would come by the end of January.

Trump attorney Clifford Robert on Monday blasted a report issued last week by the former judge appointed to monitor the Trump Organization as an inaccurate depiction of the firm's finances intended to justify the continued oversight of the company.

Robert, in his letter Monday to Judge Arthur Engoron, said the report from independent monitor Barbara Jones "twists immaterial accounting items into a narrative favoring her continued appointment, and thereby the continued receipt of millions of dollars in excessive fees," arguing that her report represented an "unacceptable level of disingenuity."

"This is truly a joke," Trump attorney Chris Kise told ABC News in a statement. "Indeed, it is shocking that President Trump has been forced to pay millions for a Monitor to prove what he has said from the outset, namely, there is no financial reporting misconduct, no fraud and simply no basis for this abusive process to continue."

A report issued Friday by the former judge appointed to serve as the Trump Organization's independent monitor by Judge Arthur Engoron found that the company has been cooperative, implemented some changes, and issued necessary corrections to financial statements; however, the report also outlined multiple errors and misstatements observed by the monitor over her 14 months in the role.

The report, by independent monitor Barbara Jones, was issued at the request of Judge Engoron ahead of his expected ruling in Trump's civil fraud trial.

"It is important to note that the Trump Organization acknowledged the disclosure issues described after I brought them to its attention and has been open to recommendations to improve accuracy and transparency," Jones wrote in her report.

However, Jones wrote, "Absent steps to address the items above, my observations suggest misstatements and errors may continue to occur, which could result in incorrect or inaccurate reporting of financial information to third parties."

A day after New York Attorney General Letitia James cited a ruling involving "Pharma Bro" Martin Shkreli to support a lifetime real estate ban for Donald Trump, a defense lawyer responded in a letter to the court calling the comparison "misplaced and irresponsible."

The New York AG said Tuesday that a federal appeals court decision upholding a lifetime industry ban for Shkreli should convince Judge Arthur Engoron to impose a lifetime real estate ban on Trump.

Defense attorney Clifford Robert, in response, wrote Wednesday that "the absurdity of the Attorney General's latest effort would be almost comical but for the sobering future consequences of her shameless abuse of power."

Robert argued that Trump's fraud case lacks witnesses, complaints, and victims compared to Shkreli's case.

In a statement to ABC News, Trump attorney Chris Kise said the ruling in Trump's case could have far-reaching implications for the New York business community.

"This is not just about President Trump. Every major bank CEO and every Wall Street participant should speak out now before the Attorney General's shocking and tyrannical interference in the capital markets places all New York business transactions at risk," Kise said.
