Donald Trump publicly claimed in the Oval Office that his father was born in Germany during talks with German Chancellor Friedrich Merz in Washington, a resurfaced remark that has sharpened questions about his memory and prompted his niece, Mary Trump to warn he may be showing signs of dementia similar to those she says affected his father. The 79‑year‑old former president made the comments while answering questions from reporters about the war with Iran, repeatedly insisting his father had been born in Germany even though official records show he was born in New York.
The renewed scrutiny of Donald Trump's mental fitness follows a string of on‑camera moments in which he has appeared to misstate basic facts, confuse timelines or mix up countries, all while positioning himself for a return to the White House. His latest misstep has struck a particularly raw nerve inside his own family, because it touches on the Trump clan's long‑documented unease over their German heritage and on a medical history that Mary Trump says includes dementia in the previous generation.
