Donald Trump's niece has offered a striking explanation for why one of the president's closest female aides appears to spend so much time in his company.
Natalie Harp, 35, has become an increasingly recognisable figure within Trump's inner circle, frequently accompanying the 80-year-old president and providing him with printed news articles, documents and other information.
Her constant presence has attracted attention, particularly after personal letters she reportedly wrote to Trump emerged.
Now Mary Trump, the president's niece and a clinical psychologist, has shared her own interpretation of their relationship during an appearance on The Daily Beast Podcast.
And her assessment was far from complimentary.
Why does Mary Trump think Natalie Harp stays so close to the president?
Mary Trump believes her uncle welcomes Harp's constant attention because, in her view, he lacks genuine emotional connections and relies on the devotion of people around him.
Speaking to podcast host Joanna Coles, Mary argued that the president's personal relationships are largely transactional, suggesting that Harp provides a level of loyalty and attention he particularly values.
She claimed that her uncle was not receiving the attention he wanted from those closest to him and that Harp appeared willing to provide it.
Mary also characterised Harp's behaviour as unusually intense, describing her as having the qualities of a stalker.
In one particularly pointed comparison, she suggested that Trump was an unusual example of someone who appeared to welcome attention that she personally regarded as excessive.
These remarks reflect Mary's opinions about her uncle and his aide. They are not independently established findings about either person's psychological state or private motivations.
Who is Natalie Harp?
Natalie Harp is a White House aide who has become one of Trump's most visible assistants.
She previously worked as a presenter for the conservative television network One America News Network before joining Trump's political operation.
Harp subsequently developed a reputation for remaining close to Trump and providing him with printed news stories, letters and other material.
That routine earned her the nickname "human printer".
Following Trump's return to the White House in January 2025, she took on official responsibilities as a special assistant and executive assistant to the president.
Her position gives her frequent access to Trump and has made her a familiar presence at political events and during official travel.
What did Natalie Harp write in her personal letters to Trump?
Harp's relationship with the president attracted additional scrutiny after The Daily Beast published details of letters reportedly written by her in 2023.
In the correspondence, Harp referred to Trump as her "Guardian and Protector" and expressed intense admiration for him.
She also reportedly described feeling deeply concerned about disappointing the president.
The letters prompted public discussion about the unusually personal language used by someone working closely with a political figure.
However, affectionate or admiring language does not establish that a romantic relationship exists.
There is no independently verified evidence that Trump and Harp have been romantically involved.
What else did Mary Trump say about her uncle's relationships?
During the podcast, Mary broadened her criticism beyond Harp, arguing that her uncle approaches relationships in terms of what each person can offer him.
She suggested that this dynamic also applied to members of his family and political circle.
Mary contrasted Harp's devotion with the behaviour of other Trump allies, arguing that even highly loyal associates can eventually reach limits in what they are prepared to tolerate.
She portrayed Harp as someone whose loyalty appeared unusually persistent.
Mary also questioned whether the relationship would receive greater scrutiny if a president from another political party spent a similar amount of time with a much younger aide.
Her comments form part of a broader pattern of public criticism of her uncle, whose political career and family relationships she has discussed extensively in interviews and books.
Why did a recent rally appearance attract attention?
Harp's relationship with the president also became a subject of online discussion following an appearance at a political rally.
During remarks about fuel policy, Trump called Harp onto the stage to bring him an executive order concerning diesel fuel used for agricultural purposes.
As Harp departed, footage showed the president turning his head in her direction.
Some social media users interpreted the moment as Trump watching his aide leave the stage, although the footage alone cannot establish what he was thinking.
Trump subsequently made a comparison involving the television game show The Price Is Right.
The interaction added to speculation surrounding their working relationship, but did not establish any inappropriate personal involvement.
Has the White House responded?
Mary Trump has repeatedly criticised her uncle's relationship with Harp in public interviews.
In response to earlier remarks from Mary about the aide, White House communications director Steven Cheung dismissed her criticism and attacked her credibility.
Reporting by The Daily Beast indicates that the White House had not provided a response to its request for comment on the latest podcast discussion at the time of publication.
Harp's own perspective on Mary's latest claims was not included in the reporting.
Why has Natalie Harp's role attracted so much interest?
The attention surrounding Harp reflects her unusually visible position within the president's immediate circle.
While presidents routinely rely on trusted assistants to manage documents, communications and schedules, Harp's frequent presence and the personal nature of her reported letters have generated questions about her influence.
For Mary Trump, the relationship illustrates what she believes is her uncle's dependence on loyalty and admiration.
Others may view Harp's constant presence primarily as a reflection of her professional responsibilities and close working access to the president.
Ultimately, Mary's explanation remains a personal interpretation rather than a proven account of why the two maintain such a close working relationship.
What is clear is that Harp has become one of the most recognisable figures around the president, and the attention surrounding her role shows little sign of disappearing.
