Mary Trump

Mary L. Trump is an American psychologist, businessperson, and author. She is a niece of President Donald J. Trump. Her 2020 book about him and the family, Too Much and Never Enough, sold nearly one million copies on the day of release.

Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man is a tell-all book written by Trump published on July 14, 2020, by Simon & Schuster. According to Trump’s note at the beginning of the book, all accounts in the book come either from her own memory or from recorded conversations with family, friends and others. Other sources are legal, financial and family documents and email correspondence as well as the New York Times investigative article done by David Barstow, Susanne Craig. The book details how the author was the anonymous source who revealed Trump family tax returns to The New York Times; the reporting won the 2019 Pulitzer Prize. A legal battle over whether the book could be published was waged in New York’s judicial system, with an appellate judge allowing Simon & Schuster to publish the book.

Trump worked for one year at the Manhattan Psychiatric Center while working on her PhD research. Trump was a contributor to the book Diagnosis: Schizophrenia, published by Columbia University Press in 2002. She has taught graduate courses in developmental psychology, trauma, and psychopathology.
