'Downward spiral': Trump's niece says his decline is 'becoming impossible to hide'

Mary Trump says the version of Donald Trump the world saw stumbling through the G7 summit is not an aberration but the trajectory, arguing in a new conversation that her uncle is in a steep psychological slide that he can no longer conceal.

Speaking with writer and journalist Steven Beschloss on her newsletter, the clinical psychologist and niece of the president responded to Beschloss's description of Trump appearing "bloated and wandering in a daze" at the summit. She did not dispute it. "I think this is simply the direction things are heading," she said, allowing that he may still have moments of relative coherence but insisting that "psychically he's in a downward spiral."

Her central argument is that the decline has become too pronounced to paper over. Trump is suffering "constant narcissistic injuries," she said, and "nothing terrifies Donald more than humiliation." The trouble for him, in her telling, is that he is his own worst enemy on that front. "Nobody humiliates Donald more effectively than Donald humiliates himself," she said.

Mary Trump tied the G7 appearance to the lavish, taxpayer-funded UFC spectacle Trump staged at the White House days earlier, which she pegged at $60 million. Everything he does now, she argued, is in service of "protecting his fragile ego" and trying to fill what she has long called "the black hole of need within him." The morning after the spectacle, she said, he discovered the familiar truth that none of it had worked. "He's still an empty, unloved man, and maintaining that illusion has become psychologically exhausting."

She framed that exhaustion as the key to understanding why the cracks are now showing. Sustaining the performance of strength, she said, is colliding with what she described as his "cognitive, emotional, physical, and psychological decline," and the combination is "becoming impossible to hide."

The decline she says she has tracked for years, in her account, is no longer something his handlers can keep off camera.
