Mary Trump

Mary Lea Trump (born May 3, 1965) is an American psychologist and author. A niece of former US president Donald Trump, she has been critical of him as well as the rest of the Trump family. Her 2020 book about him and the family, Too Much and Never Enough, sold nearly one million copies on the day of its release. A second book, The Reckoning, followed in 2021.

In September 2020, Trump sued her uncle Donald, aunt Maryanne, and the estate of her late uncle Robert, claiming that they defrauded her of tens of millions of dollars from her interests in her grandfather Fred Trump's real-estate portfolio. A year later, Donald Trump sued Mary for at least $100 million for providing The New York Times with financial documents which it used as a source for a 2018 exposé about his wealth and the family's finances.
