The Secret Service expressed concern over personal letters written by Natalie Harp, a close aide to former President Donald Trump, to the president during the 2024 campaign, according to journalist Jonathan Swan. Swan, a reporter for The New York Times, stated in an interview that the agency found Harp's letters of "absolute devotion" unusual and alarming due to her proximity to Trump.

Swan, who co-authored the book "Regime Change: Inside the Imperial Presidency of Donald Trump" with Maggie Haberman, reported that at least one letter was found in Trump's private spaces. Among the messages attributed to Harp were phrases such as "You are all that matters to me," "I don’t ever want to let you down," and "I want to bring you joy."

Despite the Secret Service's concerns, Swan noted that no specific action was taken by the agency, suggesting Trump was content with the correspondence. Swan indicated he found no evidence of Trump writing letters back to Harp. The attention on Harp and her notes has resurfaced following the release of Swan and Haberman's book.

Harp is known for carrying a portable printer and has been described as Trump's "human printer." According to the book, Trump once referred to Harp as "Nah-ta-lee" with a mock French pronunciation and told staffers that she was "the only one who loved him as much as his wife and his kids," adding, "She’ll never leave me."

Recent public attention to Harp's role also came when Sen. Jon Ossoff (D-Ga.) mentioned her during a campaign rally speech, which drew a reaction from White House communications director Steven Cheung.
