Dr. John Gartner, a psychologist and former professor at Johns Hopkins University, has raised serious concerns about Donald Trump's mental health as he approaches 80 years old. On The Daily Beast Podcast, Gartner stated that Trump is 'mentally ill and cognitively deteriorating,' and emphasized that one doesn't need a medical degree to observe these signs. He dismissed the notion that diagnosing public figures from afar is invalid, arguing that Trump's erratic behavior, particularly his late-night social media activity, indicates a mix of mania and sundowning. Gartner noted that Trump's posts often contain bizarre content, including a recent one showing him pushing a massive red button, which he interprets as a troubling signal of Trump preparing the public for catastrophic events. He described Trump as a malignant narcissist who finds power in destruction. In response, the White House firmly rejected Gartner's claims, asserting that Trump is in excellent health and remains the sharpest president in U.S. history, actively working to fulfill his promises.
