The Donald Trump aide Natalie Harp flooded a since-disabled social media account with pro-Trump posts on the day that the president’s supporters attacked the US Capitol in early 2021, years before she went to work for him and developed an extraordinary close relationship with him, a new report has revealed.

CNN on Saturday reported that a deactivated account which Harp had on what is now known as X was packed with fiercely pro-Trump messages on the day of the January 6 Capitol attack in Washington DC, including posts repeating his lies that the 2020 election, which he lost to Joe Biden toward the end of his first presidency, had been stolen from by fraudsters.

“FIGHT FOR TRUMP!” Harp wrote 12 times in one of more than 150 posts that day alone. She followed that with a post declaring: “Today, DC is TRUMP COUNTRY!”

Among her other posts was the declaration “today we STOP THE STEAL!’”. And as Trump delivered a speech that day, Harp wrote: “We will never give up. We will never concede!”

CNN’s reporting on those posts come as the US news media have put a spotlight on Harp, 35, and her near-constant presence at the side of Trump, 80, during his second presidency.

The scrutiny has been fueled by intensely affectionate letters from Harp to Trump, including one in which she called him her “Guardian and Protector in this Life”; claims from her estranged brother that her relationship with the president is “unhealthy”; and a recent speech from Jon Ossoff, a Democratic senator from Georgia, who contended that one of the few things Trump wants to do is “travel with Natalie”.

The social media account that CNN reported on, opened by Harp in 2016, also contained posts in which she compared Trump to a biblical figure, according to messages unearthed by the Daily Beast.

“We all know the story of the Good Samaritan,” Harp wrote as she went on to recount her claim that an intervention by Trump had saved her life while she grappled with cancer.

“But what you don’t know is I was that forgotten person on the side of the road – left to die of medical error and cancer. The Political Establishment passed me by. But @realDonaldTrump didn’t. Meet my Good Samaritan!” she wrote in the 2019 message.

The X account now appears to be suspended. It remains unclear when it was taken down or whether Harp or the platform was responsible for removing the posts.

Harp’s official roles are special assistant to the president and executive assistant to the president – positions that come with an annual salary of $150,000.

Inside Trump’s orbit, she has also earned the unofficial title of “human printer” – a reference to her role supplying the president with printed information.

CNN’s report on Saturday also indicated that Harp’s embrace of Trump’s election-fraud narrative began well before the day of the Capitol insurrection. In the weeks leading up to the attack, she told followers: “We will never give up – for TRUTH is on our side. January 6th is coming!!”

Her posts immediately following the election that ended Trump’s first presidency were similarly emphatic.

“WE LOVE YOU! WE LOVE YOU! WE LOVE YOU!” Harp wrote days after the election results. Then, on 14 December 2020, as she denounced Biden’s victory, Harp posted: “THIS IS A COUP.”

The resurfaced social media posts are not the only written materials now fueling scrutiny of Harp’s devotion to Trump. The Daily Beast published two intimate letters on Thursday written by the Trump aide in 2023.

Beside calling him her “Guardian and Protector”, she wrote in one letter: “You are all that matters to me.”

She also wrote: “I want to bring you joy, to feel like we can get through a day without ever having to talk ‘work.’”
