New York Attorney General Letitia James is turning even more heat on former president Donald Trump by asking a federal judge to sanction him, his three eldest children, and their attorneys for making “demonstrably false” denials in regard to the $250 million fraud lawsuit James filed last year against the Trumps and the Trump Organization, Newsweek reports.

In a letter from her office, James has asked Judge Arthur Engoron to hold a hearing to consider the sanction requests. The letter also states that the Trumps, via their attorneys — recently said they lacked “sufficient knowledge” in legal brief responses to questions surrounding the allegations in the lawsuit. The letter asks Engoron to accept some of the Trump responses as “improper” and to reject some of their defenses.

Trump, Donald Trump Jr., Ivanka Trump, and Eric Trump are each cited in the letter, signed by Kevin Wallace, senior enforcement counsel in the attorney general’s office.

“Defendants falsely deny facts they have admitted in other proceedings, they deny knowledge sufficent to respond to factual allegations that are plainly within their knowledge, and they propound affirmative defenses that have been repeatedly rejected by the Court as frivolous and without merit,” he wrote.

The letter notes one obvious contradiction, something that may well be a conflict of interest: Trump denied serving as the inactive president of the Trump Organization during his time in the White House, despite saying in sworn testimony that he did actually act in that capacity.

Donald Trump Jr. and his brother Eric were also named in the letter for claiming they were “being improperly targeted for investigation,” even though the court rejected their “witch-hunt” argument. Eric has also been cited for denying that the Trump Organization in 1995 acquired Seven Springs property for $7.5 million. Even though he’d previously admitted to this in a proceeding.

Ivanka is also named in the letter for denying knowledge or sufficient information “as to whether she personally met with bankers, or whether she can confirm the contents of her own emails.”

James announced her $250 million lawsuit against Trump and his older children in September. But all of them continue to deny any wrongdoing and characterize the lawsuit as being politically motivated.

And James and Donald Trump have been dueling it out ever since the announcement of the lawsuit, waging legal actions against each other. Trump filed a lawsuit against James in November, attempting to block her from accessing records from a trust he’d established in Florida that has ownership of the Trump Organization. Trump, however, withdrew the lawsuit earlier this month.

Last April, Judge Engoron held Donald Trump in contempt of court. The former president was sanctioned and fined $10,000 per day because he failed to comply with a subpoena issued by James for her investigation.
