President Donald Trump’s mental sharpness is slipping in ways that show up whenever he strays from a prepared script, according to his niece, who argues the 80-year-old can no longer “read the room” as he once did. Mary Trump, a 61-year-old clinical psychologist and one of the president’s most persistent public critics, discussed her concerns on the “Fast Politics” podcast with journalist Molly Jong-Fast, citing several recent public appearances as evidence.
During Tuesday’s eulogy for Sen. Lindsey Graham, Trump departed from his prepared remarks to note that “not everybody” had liked the South Carolina senator. Mary Trump and Jong-Fast said the unprompted comment at a memorial service was revealing of the president’s diminishing self-control.
A Lost Ability to Recalibrate
Mary Trump said her uncle previously demonstrated better judgment about when to restrain himself. She said he “did have the ability to read the room better,” describing a man who used to push boundaries and then adjust course in real time when the reaction turned against him.
To illustrate the point, she reached back to a rally at which Trump praised the COVID-19 vaccine, only to be booed by portions of his Make America Great Again base. After that reception, she noted, the subject vanished from his speeches. It was, in her telling, evidence of a politician who once read a crowd and corrected instantly. That skill, she argued, has eroded. He is losing impulse control, she said, framing it as one piece of a broader cognitive decline.
The conversation turned to the rescheduled White House Correspondents’ Dinner on July 24. Trump’s prepared jokes fell flat, including one comparing CNN anchor Kaitlan Collins to transgender influencer Dylan Mulvaney. Jong-Fast recalled that the president criticized the speech itself and pressed on, leaving much of the audience stunned.
Mary Trump described the spectacle of an aging man reading unfamiliar material he had no hand in writing, then drifting into personal grievances before a crowd he views as adversarial. She added that his failure to sense the room was underscored when he told the same joke about seeking a third term in 2028 — a scenario the Constitution forbids — not once but three times.
The White House Fires Back
White House spokesperson Davis Ingle dismissed Mary Trump as a “stone-old” loser and contrasted the president’s energy with what he called a coordinated effort to hide former President Joe Biden’s decline.
White House Communications Director Steven Cheung had earlier used similar language, calling her a “stone-old loser who doesn’t have a clue about anything.”
That column responded to a campaign-style rally at a Georgia high school, where the president promoted his administration’s “Trump Accounts” program and declared that the country had entered a “golden age.” Launched July 4, the initiative deposits $1,000 into accounts for qualifying children born from January 1, 2025, through December 31, 2028, with provisions allowing additional contributions from families and employers. The Committee for a Responsible Federal Budget projects the program will cost roughly $17 billion through 2028.
Mary Trump questioned both the timing and the substance of those claims, citing a Washington Post-Ipsos poll in which just 33% of respondents approved of the president’s handling of the economy while inflation held near 3%. She wrote that much of what her uncle described does not exist beyond his imagination, and accused him of assuming that sheer repetition could turn fiction into fact.
A Familiar Family Diagnosis
Mary Trump’s critiques trace back to her family history and her professional training. The daughter of Fred Trump Jr., the president’s late brother, she is the granddaughter of Fred Trump, the family patriarch. Her 2020 memoir, “Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man,” published by Simon & Schuster, sold nearly a million copies on its first day, surviving a court challenge from the president’s younger brother, Robert Trump, to block it.
On her “Mary Trump Live” show, she has argued that the president’s relentless pursuit of accolades — including the first-ever FIFA Peace Prize from FIFA President Gianni Infantino — stems from a paternal void. The one thing he most needs, she said in December 2025, is something no medal can supply. “Nothing, nothing can replace love,” she said, adding that “all of us are paying that price.”
