Mary Trump, President Donald Trump’s estranged niece, has revealed for the first time that she got married in October “in front of a small group of some of our family and closest friends.”
“I am married not only to the love of my life but to my best friend,” she said in her most recent Substack entry “Reader, I Married Her” on Sunday evening.
“The psychologist and writer added: “Because I opened myself to the possibility that was held out to me almost a year ago, my other relationships have deepened in new and unexpected ways. I am happy in a way I never would have dared imagine.”
She added: “There is more to the story, of course—including the reason for my not having spoken of my marriage publicly before this—and times continue to be challenging. The first eleven days of 2026 represent an escalation of the horrors we experienced as a country since January 20, 2025, that is as shocking as it is predictable.”
