That has all changed since it emerged the 35-year-old was one of a handful of people who secretly swapped from Air Force One with Trump in Turkey after a security threat.The blonde executive assistant to the president was then mentioned by a Democratic senate hopeful, in comments that set the internet alight -- and incensed the White House."He wants to build his ballroom and travel with Natalie on their apparently defenseless flying palace gifted by the Emir of Qatar," Jon Ossoff, who is widely viewed as a 2028 presidential contender, said in a speech at the weekend.But just who is this aide to the 80-year-old Trump, who reportedly has not taken a single day of holiday since the Republican returned to power last year? 'Never leave me'Harp has been dubbed the "human printer" -- thanks to her role carrying a portable machine to print out documents that Trump asks for. But that severely underestimates her role.She effectively functions as a gatekeeper to the president by controlling the information that gets through to Trump -- often reportedly pointing him towards right-wing material on social media.Harp is also one of the few officials with direct access to Trump's Truth Social account. She types out posts as Trump dictates them, even inserting his trademark capital letters, according to footage in the documentary "Art of the Surge" on the 2024 election campaign.
