President Donald Trump’s much-scrutinized reliance on White House aide Natalie Harp makes him look “pathetic,” his niece, Mary Trump, said in an interview released August 26, 2026. A bigger worry, she added, is the security risk she believes the arrangement creates around a president she characterized as a failing old man.
Mary Trump, 61, who holds a doctorate in clinical psychology and wrote “Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man,” was a guest on “The Jim Acosta Show,” the independent program the former CNN anchor launched after leaving the network. Harp’s round-the-clock presence, in her telling, is one more marker of the decline she sees in her uncle. “It makes him look like such a pathetic, frail, needy old man that he has to have a woman young enough to be his granddaughter constantly with him, protecting him, making sure that he sees positive press clippings about him,” she said.

A wounded ego is what the setup exposes, she argued, describing an uncle who is in trouble, lashing out and desperate to change the narrative. “He needs somebody constantly filling his head with compliments and positive messages — and she fits the bill, I have to say that,” she told Acosta.
Mary Trump called the setup extreme and over the top. Her sharpest words, though, were about the country rather than the optics. “She presents a very real national security threat to the United States of America, all because the president is a flailing, failing old man whose ego is fragile,” she said. “That’s the most alarming thing about it to me.”
Who Natalie Harp Is
Harp, 35, is Trump’s executive assistant, known for fierce loyalty. Photographers routinely catch her a step or two behind the president, hauling stacks of paper or outsized bags. Her nickname, “the human printer,” comes from the portable printer she brings everywhere, so she can hand him hard copies of social media posts and favorable columns.
Government officials have questioned her closeness to the president before. Two letters she wrote to Trump during the 2024 campaign troubled the Secret Service, according to reporting by the biographer Michael Wolff, who obtained them from campaign staff; The Daily Beast published them in full on August 20. Written after a May 2023 golf trip to Scotland, they carry a run of apologies — for walking the course instead of riding, for losing her focus, for forgetting to eat and sleep — and one closes “With all my heart.” She also declined for more than a year after Trump returned to office to complete a routine security clearance, until the president personally intervened. In October 2023, during the New York civil fraud trial, she climbed into the trunk of one of the motorcade SUVs when there was no seat for her.
The Flight That Restarted the Conversation
An unusual travel episode put Harp back in the conversation. Officials described a credible Iranian plot to fire a missile at Air Force One, and on July 8, leaving a NATO summit in Ankara, Trump boarded the 747 on camera, then slipped out another door into an airport catering truck and transferred to a smaller Air Force jet while the 747 flew on as a decoy. Harp was aboard the second aircraft, along with Defense Secretary Pete Hegseth and two other aides. A later investigation found no evidence the missile team had been in place.
Sen. Jon Ossoff, D-Ga., seized on that reporting at an Atlanta rally on August 16. “He wants to build his ballroom and travel with Natalie on their apparently defenseless flying palace gifted by the Emir of Qatar,” he told supporters. Pressed the next day on why he had named her, he declined to explain and broadened the point to the senior staff generally; two days after that he invoked her again and mocked the backlash.
The president’s allies answered fast, and personally. White House Communications Director Steven Cheung aimed a vulgar insult at the senator, and spokesman Davis Ingle branded Ossoff a cringeworthy theater kid cosplaying as former President Barack Obama.
In the Oval Office on August 17, asked about Ossoff’s comment by CNN’s Kristen Holmes, Trump likened the senator’s looks to Pee-wee Herman’s: “You mean Pee-wee Herman? Pee-wee Herman lookalike?” The White House “Rapid Response” account on X then turned on Holmes: “Someday, your children will come across your disgusting and inhumane question.” CNN said personal attacks on journalists for asking questions are “beneath the office and inconsistent with the principles of a free press.”
A Feud That Split Two Families
By the time Mary Trump weighed in, relatives had already made the episode a family matter. An unhealthy obsession is how the aide’s estranged brother, Preston Harp, described his sister’s attachment to the president, telling CNN on August 18 that he found it sad.
Eric Trump, the president’s son, hit back on X on August 19. He called the interview absolute trash, said that from the looks of it Natalie Harp had got all the family genetics, and described her as a cancer survivor and a genuinely good person who ranks among the hardest-working people in the White House. “She’s deeply committed to my father, to her job, and to this country,” Eric Trump wrote.
The dispute has since drawn in relatives on both sides, a sitting senator, the White House press operation and two cable news reporters. Harp herself has said nothing publicly. She was named a defendant on August 12 in a suit brought by The Intercept and the Freedom of the Press Foundation over a paid service offering early access to the president’s posts, alongside Trump and deputy chief of staff Dan Scavino; the plaintiffs moved on August 31 for an order barring the arrangement. And on Sunday, September 13, after Harp travelled with the president to Ireland, the White House rapid response account attacked a journalist who posted a photograph of her in Dublin, calling him a “sick, deluded freak.”
