When cardiologist and George Washington University professor Dr. Jonathan Reiner watched Donald Trump deliver a roughly 20-minute public address.
He was not focused on tax policy, foreign affairs, or campaign rhetoric. Instead, his attention was drawn to the presentation itself.
The pace, tone, and physical demeanor of the speaker.
What concerned him, Reiner later explained, was not the content of the speech but what he interpreted as an unusually intense and pressured delivery style.
According to Reiner, Trump’s voice appeared elevated, his words came rapidly, and the overall cadence felt accelerated to the point of discomfort.
He likened the experience to listening to an audio recording played at double speed.
For a figure occupying or seeking the highest executive office in the United States, Reiner said, such a delivery can feel unsettling — not necessarily because it proves anything definitive, but because it raises questions about self-regulation, stress levels, and physical stamina.
It is important to note that Reiner’s comments represent personal medical observations, not a diagnosis.
He has repeatedly emphasized that he has never examined Donald Trump and cannot assess his health directly.
Nonetheless, as a physician who has spent decades observing cardiovascular health and stress responses, Reiner argues that the public has a legitimate interest in discussing observable behavior — particularly when it comes from individuals who wield enormous power.
