Donald Trump says Joe Biden shows no cognitive decline, while niece critiques his own brain tests

President Donald Trump told reporters on June 4, 2026 that he did not notice any signs of cognitive decline when he met former President Joe Biden in the Oval Office in November 2024, describing Biden as “the same guy I’ve been watching for a long time.” Critics on social media called the answer odd and highlighted Trump’s earlier claims that Biden would struggle with basic cognitive tasks.

Separately, Trump’s niece, clinical psychologist Mary Trump, denounced the White House health czar Dr. Mehmet Oz’s explanation for the president’s repeated cognitive assessments. Oz claimed Trump “likes the results” and “aces the test every single day,” a justification Mary Trump called “absurd,” noting the contradiction between Trump’s cited war‑time demands and his frequent trips to Walter Reed for tests he has already passed.
