Dick Cheney's former physician increasingly worries over Trump's overall health

Cardiologist Dr. Jonathan Reiner expressed grave concerns about President Donald Trump's physical and mental health ahead of his third Walter Reed medical checkup in 13 months.

In conversation with "CNN News Central" Reiner called for mandatory presidential health disclosures to Congress and the public, comparing the matter to fitness requirements for pilots and Secret Service agents.

He demanded credible explanations for Trump's visible health issues, including bruising attributed to "vigorous handshaking"—which Reiner argued is an insufficient explanation — and severe ankle swelling diagnosed as chronic venous insufficiency, despite no edema appearing earlier in the year.

Most concerning to Reiner is Trump's severe daytime drowsiness, or somnolence, including multiple instances of falling asleep in the Oval Office and potentially during the Arlington National Cemetery Memorial Day observances.

Chronic insomnia increases dementia risk, decreases cognitive function, raises cardiac complications, and ages the brain by 3.5 years, Reiner explained.

The prominent CNN medical analyst has become a leading voice questioning Trump's fitness for office.
