The New York attorney general's office says a federal appeals court decision upholding a lifetime industry ban for disgraced "Pharma Bro" Martin Shkreli should convince Judge Arthur Engoron to impose a lifetime real estate ban on Donald Trump.

In a letter to Judge Engoron, state attorney Colleen Faherty cited Tuesday's decision in the Shkreli case to justify the NY AG's request to ban the former president from the New York real estate industry for life.

According to Faherty, New York State Executive Law 63(12) -- which was used in the NY AG's lawsuits against both Trump and Shkreli -- gives the court the ability to "issue a permanent and plenary ban in a particular industry."

"63(12) is the Swiss Army knife of the AG's Office," said Tristan Snell, a former lawyer with the New York attorney General's office who used the law to sue Trump over the now-defunct real estate seminar called Trump University. "If you don't have laws like this in place, that you basically allow lies and misrepresentations to be endemic."

A final decision in Trump's civil fraud case is expected later this month.

New York Attorney General Letitia James on Friday released video of former President Trump's April 2023 deposition in the case.

Video of the deposition, the transcript of which was released by the attorney general in August 2023, was released as part of a public records request.

As ABC News reported in August, Trump in the deposition called his real estate portfolio "the Mona Lisa of properties" and suggested his assets were worth far more than what appeared in his statements of financial condition that are at the center of the New York AG's case.

The videotaped deposition proved to be a preview of Trump's testimony at trial earlier this month, in which he bragged about his finances and declared himself "an innocent man."

New York's highest court has upheld the limited gag order in Donald Trump's civil fraud trial.

"On the Court's own motion, appeal dismissed, without costs, upon the ground that no substantial constitutional question is directly involved. Motion for a stay dismissed as academic," New York's Court of Appeals said in a two-sentence ruling issued Tuesday.

The gag order barred Trump and his lawyers from commenting on Judge Arthur Engoron's staff during the former president's 11-week civil fraud trial.

A decision in the case is expected later this month, after closing arguments wrapped up last week.

New York State Attorney General Letitia James, speaking to reporters outside court following the conclusion of closing arguments, dismissed the idea that her case against Donald Trump is about politics.

"This case has never been about politics, personal vendetta, or about name calling. This case is about the facts and the law, and Mr. Donald Trump violated the law," James said.

James thanked her team, the judge, and Trump's lawyers before repeating her confidence that "justice will be done" in the case.

"No matter how powerful you are, no matter how rich you are, no one is above the law," she said.

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."
