Doctors warn Trump's cognitive decline endangers his ability to serve

newsJun 6, 2026833

More than 30 neurologists, physicians and scientists from leading U.S. institutions sent a letter to Congress saying President Donald Trump's accelerating cognitive decline threatens his ability to carry out presidential duties. The letter documents worsening memory, chronic lack of sleep, and what it calls 'frequently manic' late-night posting as evidence of impaired judgment and executive function. Signatories including Fein and Nader warned the decline could make Trump prone to impulsive decisions, even potentially ordering nuclear strikes 'against Iran in a fit of rage.' The authors urge Congress to consider medical fitness evaluations because impaired presidential cognition poses direct risks to national security and crisis decision-making.
