Mary Trump Comments on Donald Trump's Net Worth

Donald Trump's estranged niece has once again laid into her uncle, this time about his ability to pay the enormous fine ordered by a New York court last week.

Writing in an edition of her newsletter "The Good in Us" delivered to subscribers on Wednesday, the former president's niece Mary Trump said her uncle was a "loser" who is obsessed with his net worth and said he may not have enough to cover the penalty arising from his civil fraud trial in New York.

Trump and his real estate organization were found to have misrepresented the business' assets to get favorable loans and interest rates. New York Attorney General Letitia James, prosecuting, has since said she will aim to seize his assets, including his 40 Wall Street skyscraper, if he does not pay the $354.8 million civil fraud fine. "If he does not have funds to pay off the judgment, then we will seek judgment enforcement mechanisms in court, and we will ask the judge to seize his assets," she told ABC News on Tuesday.

Trump has consistently denied any wrongdoing. In total, he owes $453.5 million due to the court applying $98.6 million in pre-judgment interest. His attorney Alina Habba, who has called the trial a "witch hunt," has said the decision would be appealed. Newsweek has contacted Trump via the contact form on his website for comment.

Referring to the comments made by James, Mary Trump said she threw "cold water" over any hopes the former president might have of winning his appeal. She said that his first problem was the overwhelming evidence based of "hard facts" that "clearly contain fraudulent valuations that defendants used in business."

Mary Trump then said James implied that her uncle does not have the funds to pay off the enormous sum, which she said is "enough alone to enrage him."

"Donald is obsessed with his net worth and he goes to great lengths to convince people he is enormously wealthy. It's a significant part of his identity," she wrote. "The urgency with which he clings to the the false idea that he is richer, more successful, and more talented than he is serves to hide the truth—not just from us, but from himself—that he is, quite simply, a loser."

She said her uncle is reported to have in excess of $400 million in cash, according to a report by CNN, which would not cover the entirety of the penalty he owes.

Mary Trump said that due to the E.Jean Carroll case, in which he was ordered to pay $83.3 million for defaming her, he could be at risk of liquidation. "If you consider that his debt is constantly increasing, because interest is calculated daily, his chances of avoiding liquidation are in serious jeopardy," she wrote.

It is unclear if the judge in the civil fraud trial will agree to delay the start of when Trump must pay the $355 million or post the cash bond to appeal.

Greg Germain, a law professor at Syracuse University in New York, previously said that Letitia James would be able to "levy and sell" Trump's property to pay for the judgment.

"The properties would probably be sold whether Trump wants to sell or not, unless he could come up with the cash to pay the judgment in full," he said.

Germain added that Trump's business assets would not be exempt from the judgment.

"A judgment creditor can go after whatever assets the creditor wants to, unless they are exempt from execution, and business assets are not exempt from execution. Usually creditors go after the most liquid assets first," he said.
