Mary L. Trump is an American psychologist and author. The niece of Donald Trump, she wrote Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man (2020), which sold nearly one million copies on the day of its release and is considered a serious game-changer in the US presidential elections that Donald Trump lost decisively to Joe Biden. Trump holds a PhD in clinical psychology and, as an adjunct professor at Adelphi University, taught graduate courses in developmental psychology, psychopathology, and trauma. She also has an MA in English and Comparative Literature from Columbia University. Her latest book, The Reckoning: Our Nation’s Trauma and Finding a Way to Heal (2021), attempts to diagnose the current state of American society by examining the twin traumas — the genocide of the native population and the enslavement of Africans — in which it was born. Trump argues that these crimes have never been atoned for and only barely acknowledged and that they have led America to the current fraught political moment in which the future of liberal democracy hangs in the balance.
