Mary Trump Is Suing Uncle Donald for Allegedly Defrauding Her of Millions

President Trump’s niece filed a lawsuit against her uncle and his siblings that accuses them of fraudulently cutting her out of her grandfather’s estate.

The lawsuit represents a fresh battle in the ongoing Trump family feud, which erupted after Mary went public with her best-seller, a tell-all book with bombshell claims about her uncle and their family.

The lawsuit was filed in the state of New York against Trump, his sister Maryanne Trump Barry, and the estate of their late brother, Robert Trump. The suit accuses them of conspiring to keep Mary from inheriting her rightful share of her grandfather Fred Trump’s fortune after his death in 1999.

"Rather than protect Mary's interests, they designed and carried out a complex scheme to siphon funds away from her interests, conceal their grift, and deceive her about the true value of what she had inherited," the suit says.

“My father died when I was still a teenager, and my uncles Donald and Robert and aunt Maryanne were supposed to be protecting me as my trustees and fiduciaries,” Mary Trump said in a statement. “Recently, I learned that rather than protecting me, they instead betrayed me.”

A White House spokesperson didn’t immediately return a request to comment from VICE News.

The lawsuit says that Mary, 55, inherited a valuable stake in her family’s business empire after her father’s death in 1981, when she was 16. In her memoir, “Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man,” she writes about growing up with only a hazy understanding of the full extent of her grandfather Fred’s real estate holdings.

Mary’s lawsuit alleges that after Fred’s death, her family then took advantage of the situation: “They presented her with a stack of fraudulent valuations and a so-called settlement agreement, and forced her to sign. All told, they fleeced her of tens of millions of dollars or more.”

In her book, Mary recounts how she only gained insight into the true size of her grandfather’s fortune after reporters for The New York Times contacted her a few years ago while reporting about President Trump’s finances.

Mary then went back to examine old documents, which she also passed along to the Times reporters. Those documents helped form the basis of a bombshell Times report detailing how Trump inherited vast sums from his grandfather, in part “because he helped his parents dodge taxes.”

Like her book, Mary’s lawsuit is digging deep into her family history, seeking a judgement on events that happened decades ago and helped propel her uncle Donald first to prominence and then to the White House.

The first sentence of Mary’s lawsuit states that for the Trumps, “fraud was not just the family business—it was a way of life.”

Now, Mary has taken her previous claims and put legal muscle behind them—in what promises to be a titanic struggle over the origin of President Trump’s private fortune, playing out inside a New York courtroom.
