The fully released letters of President Donald Trump's aide Natalie Harp are drawing unease over the way she writes to him.

The letters were made public Thursday evening by Trump biographer Michael Wolff, whose previous books on the president include Fire and Fury, and The Daily Beast, which produces his podcast Inside Trump's Head, and online critics reacted to them on Friday. Harp has been in the spotlight recently after Sen. Jon Ossoff, a Georgia Democrat, called out the president for preferring to "travel with Natalie Harp" rather than do his job, a remark that drew scrutiny to her relationship with Trump.

Harp, a former One America News host, has served as a Trump aide since his first term, and White House reporters have previously described her carrying a portable wireless printer to print news articles for him to read, including while accompanying him on the golf course. Her public ties to Trump go back years: speaking at the 2020 Republican National Convention, Harp, who survived bone cancer as a young adult, credited the Right to Try law Trump signed in 2018 with helping save her life.

One line, highlighted in a post by HuffPost editor Philip Lewis, read: "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."

Ron Filipkowski, editor-in-chief of the political news network MeidasTouch, noted that Harp randomly capitalizes words in the same way Trump does and connected the stylistic overlap to reports that she drafts Trump's Truth Social posts.

"The syntax and random capitalizations in Natalie Harp's letters to Trump are a Rosetta Stone that can be used to determine which he wrote and which are her writing him," Filipkowski posted on X.

"Y'all, this woman isn't well," wrote former GOP strategist Rick Wilson.

"Lots to unpack in this Natalie Harp letter," reacted ex-Trump White House deputy press secretary Sarah Matthews. "But this line in particular stood out to me: 'I was approaching burnout, and starting to envy those whose only 'job' seems to be to talk with you, and look pretty.' Lol."

"This is some freaky stuff," warned Democratic political commentator Harry Sisson. "Anyone with a brain can see that."

Podcaster and political extremism researcher Jared Holt described Harp's letter as "ten times scarier than a death threat. If anyone ever sent me something like this I would seek a restraining order as soon as humanly possible and be legitimately scared for my safety." (X post)

"Please tell me this isn't real," CNN contributor Ana Navarro-Cárdenas pleaded on X.

Progressive political commentator Molly Jong-Fast joked, "There's no chance that Donald Trump made it to the end of this letter."
