'Smoking gun': Mary Trump exposes 'note from hell' that could cost her uncle everything

Former President Donald Trump's niece Mary Trump explained in her Substack Wednesday why a five-word "note from hell" written by the Trump Organization's top accountant could cost her uncle everything in the civil fraud trial in New York.

"A scribbled note said to have been written by former Trump Organization Comptroller Jeffrey McConney reads: 'DJT TO GET FINAL REVIEW.' The note appears on a document that allegedly exaggerated Donald’s net worth by $3.5 billion, and contained expansive evidence of fraud," wrote Mary Trump, herself a professional psychologist. "I shared this evidence with attorney Joe Gallina of Call to Activism, who said, 'I can’t think of a bigger smoking gun than one that says – in all caps – 'DONALD TRUMP MUST APPROVE THIS' on a document riddled with fraud.'"

The problem for the former president and his adult sons, who are currently on trial for exaggerating and manipulating the value of their assets, is that their primary defense is that they simply followed their accountants' advice — and this piece of evidence would directly contradict that.

But there's another reason this is a devastating blow to Trump's case, she wrote.

"This potentially deal-breaking document was NOT provided in discovery by Donald’s lawyers. Instead, it was handed over by Mazars, Donald’s financial auditing company," wrote Mary Trump. That means that Trump's lawyers weren't fully transparent in the discovery process — and they could be in trouble right along with him.

New York Attorney General Letitia James is seeking hundreds of millions of dollars in fines, as well as the abolition of the Trump Organization within the state. Judge Arthur Engoron, who is overseeing the case, has already ruled for the state on summary judgment for fraud, and the trial is mainly an assessment of potential damages.
