Mary Trump publicly criticized her uncle, President Donald Trump, on Tuesday, October 28, 2025, after he discussed his cognitive test results from his recent physical examination at Walter Reed Medical Center. The president’s estranged niece took to social media to challenge his boasting about the assessment, calling him a “moron” in a post that quickly gained attention.
The 79-year-old president had met with reporters following his physical at Walter Reed, where he explained the nature of the cognitive test he had taken. He described the questions as starting easily before becoming progressively more difficult. Trump then criticized Democratic Representatives Alexandria Ocasio-Cortez and Jasmine Crockett, characterizing them as low-intelligence individuals who he claimed would fail the assessment.
Mary Trump, a trained psychologist and daughter of Donald’s older brother Fred, responded with a sharp rebuke on X. “Just a quick reminder: bragging about results of the cognitive test is to fail the cognitive test, moron,” she wrote in her post.
The president had elaborated on the test format, explaining that initial questions involving animals like tigers, elephants, and giraffes were straightforward. He told reporters that as the questions progressed to five, six, ten, 20, and 25, the representatives he mentioned would struggle to answer correctly. His comments sparked immediate responses from both Ocasio-Cortez and Crockett.
Representative Ocasio-Cortez responded directly to Trump’s remarks on Monday, sharing video of his comments and questioning whether doctors had asked him to draw a clock during the examination. She referenced this specific test component, which medical professionals often use to assess cognitive function, particularly in patients showing potential signs of dementia. The inability to complete this task accurately can indicate mental decline.
Representative Crockett addressed the situation during an interview with CNN’s Kaitlan Collins, expressing her desire for a reporter to question the president about his actual IQ score. She responded to his characterizations of her intelligence with measured skepticism about his own cognitive abilities.
Mary Trump has maintained a contentious relationship with her uncle for years, particularly since he began his first presidential term in 2017. She authored multiple books critical of the president, including Too Much and Never Enough and The Reckoning, both of which examine the Trump family dynamics and her uncle’s behavior. In her 2020 book, she characterized him as utterly incapable of leading the country and dangerous in that role.
The psychologist has described herself as the black sheep of the family, noting she no longer maintains relationships with any family members except her daughter. She has publicly characterized her grandfather, Fred Trump, as a sociopath and identified cruelty as a recurring theme within the family structure.
In previous interviews, Mary Trump recounted her experience working with her uncle in her late 20s when Donald hired her to ghostwrite his book, The Art of the Comeback, though she was ultimately fired from the project. She spent six months in his office, which provided insight into his personality and behavior. She has consistently described him as someone incapable of close relationships and noted he remains unchanged from his younger years.
Trump filed a lawsuit against his niece in 2021 seeking $100 million in damages after she provided information to The New York Times for their investigation into his financial dealings. Mary Trump has stated the legal action represents a clear message, but maintains she will not be intimidated by such tactics.
At speaking engagements, she has characterized her uncle as provincial and described witnessing his behavior from childhood through adulthood. She recounted stories from family friends who knew Donald as a teenager, describing him as cocky, rude, and intensely jealous of his older brother Freddie. According to these accounts, Donald lacked friends and proved difficult for others to tolerate.
Mary Trump told audiences in May 2025 that developmental issues during Donald’s childhood, particularly the absence of his mother due to health complications, left him primarily under the influence of his father during crucial formative years. She suggested this dynamic significantly altered the trajectory of his life and personality development.
