Trusted White House aide Natalie Harp displayed ‘erratic’ behavior while working on President Donald Trump‘s 2024 campaign, a new book claims.

In an excerpt from from Revenge: The Inside Story of Trump’s Return to Power obtained by DailyMail.com, Axios’ Alex Isenstadt described Harp’s strange behavior on numerous occasions leading up to the election.

The most notable instances included Harp wrecking her car into a Secret Service vehicle, sending Trump a series of ‘obsessive’ letters and being ‘prickly’ with her coworkers.

‘Natalie’s behavior was increasingly drawing attention,’ Isenstadt wrote. ‘Particularly concerning: The Secret Service had obtained handwritten letters Natalie had given Trump in which she came off as obsessive, adoring, and desperate for his approval.’

The White House denied the ‘malicious falsehoods’ made in the book about Harp in a statement.

DailyMail.com exclusively reported earlier this week that Harp as made herself such a crucial part of Trump’s inner circle, she’s practically ‘unfireable.’

As a result, she earned herself a new nickname – ‘Fatal Attraction’ – to describe how closely she followed the president around – much like Glenn Close‘s psychotic character in the film, Alex Forrest.

In her role as the so-called ‘Human Printer,’ Harp would generally travel behind Trump in a golf cart, wireless printer in tow.

Isenstadt wrote that in one letter of devotion, Harp apologized to Trump for her behavior ‘on the course in Scotland.’

It is unclear what it was in direct reference to, but Harp had chased behind Trump on foot during a golf outing in Aberdeen, Scotland, when a golf cart wasn’t made available to her.

The letter continued with Harp telling Trump, ‘I want things to always be right between us.’

‘I also know I’ve been distracted all week (forgetting to eat throughout the days, and even forgetting to sleep, and only catching a couple hours at a time) … I started letting the remarks of people who haven’t bothered me before, get to me – not because I care what others think, but because I see myself being lowered in your eyes and good opinion,’ she said.

‘That is the fear you see, because I never want to bring you anything but joy,’ she told Trump.

She continued: ‘I’m sorry I lost my focus. You are all that matters to me. I don’t want to ever let you down. Thank you for being my Guardian and Protector in this Life.’

The aide concluded the letter by saying, ‘I will return a better person. I have to sign off now, as the cars are leaving. See you soon. With all my heart, Natalie.’

In a second letter, quoted in Isenstadt’s book, Harp wrote about how the trip had given her time to reflect on her work for Trump.

Natalie Harp is seen arriving at Trump Tower amid the Stormy Daniels hush money trial last year. In 2023, she wrote a series of devoted letters to then former President Donald Trump, calling him her ‘Guardian and Protector in this Life’

‘I need to reunite my past self with my current into a better version who will make you proud,’ she wrote. ‘And please, when I fail, will you tell me? You have the absolute right to cuss me out, if need be, when I deserve it, because no one knows or cares about me more.’

The existence of the letters was first reported by The New York Times in November after the election, as Trump made it official that Harp would move from his campaign to 1600 Pennsylvania.

The letters she had given Trump in 2023, ‘unnerved people around him,’ The Times said.

And ‘Harp’s behavior over time grew more erratic,’ Isenstadt described.

He reported that Harp had jumped into her car after staff had deplaned from ‘Trump Force One’ at the Palm Beach International Airport one evening.

The aide ‘floored the gas, and then slammed into a parked Secret Service SUV.’

‘Harp got out of her vehicle, threw her hands up in the air, and asked a few aides who’d witnessed the accident what she should do,’ he wrote. ‘Was it bad? Did anyone else see it happen? Should she leave a note?’

Harp showed less appreciation for her coworkers.

‘What do you want?’ Harp reportedly snapped at Susie Wiles, who’s now the White House chief of staff, when the campaign co-chair called the aide one day.

Harp had ‘apparently been on another golf outing with Trump,’ Isenstadt wrote.

The aide even reportedly clashed with Eric Trump at one point by ‘back-channeling with Eric’s employees at the Trump Organization.’

‘Eric told Harp that she was unprofessional and asked her not to go behind his back anymore,’ Isenstadt wrote.

In another instance, Harp tussled with Walt Nauta, Trump’s full-time valet, over the task of removing a box of papers, telling Nauta ‘This is my job to take them … He told me to take it.’

And Harp didn’t appear to like the other women in Trump’s tight circle.

‘Harp derisively labeled some women in Trump’s orbit—people like Alina Habba, press aide Margo Martin, and lawyer Lindsey Halligan—the “Party Girls,” even though there was no evidence that any of them had acted inappropriately,’ Isenstadt wrote.

White House Communications Director Steven Cheung pushed back on the book’s assertions in a statement to DailyMail.com.

‘These are pure malicious falsehoods that have no basis in reality. This book should be thrown out into the dumpster and lit on fire,’ he said.

‘The fact remains that Natalie Harp is one of the most dedicated individuals in Trump World who has always done everything to benefit President Trump and the entire team,’ Cheung said.

‘President Trump has built the most dominant political team in history and, through his leadership, the campaign won in a decisive and historic fashion.’

Revenge will be released March 18.
