Harp is said to have keys to Trump’s Truth Social account and to post on his behalf. The book claims she left letters in private spaces — including one reading, "You are all that matters to me" — and that Trump told staff she loved him as much as his family. Her taste in imagery and messages has at times sparked controversy, with several social posts drawing criticism.
Sources describe Harp as a fixture from the Oval Office to golf outings, often filtering news toward the president and even cheering on his decorative choices in the residence. The portrayal in Regime Change paints her as both devoted and influential in the president’s inner circle.
