Harp's estranged brother Preston told CNN that Trump's affinity for loyal, admiring people may explain their bond and called one rumored episode "kind of sad," calling it "obsession." A book by New York Times reporters noted Harp left letters in Trump's personal spaces, one reading, "You are all that matters to me." Michael Wolff has written that some in Trump's circle believe Harp is "hopelessly in love" and aspires to be a "higher purpose bride."
Wolff also suggested Melania Trump kept distance from public appearances when Harp was present, a point raised in discussions about Harp's place around the president.
