Trump Challenges Biden to Cognitive Test, Then has Immediate Mental Lapse Showing Loss of Cognition.

Trump couldn't even remember the name of the physician who gave him a previous test for dementia, during a speech in Detroit.

"I think he should take a cognitive test like I did. Doc Ronny Johnson. Does everyone know Ronny Johnson, congressman from Texas? He was the White House doctor, and he said I was the healthiest president, he feels, in history, so I liked him very much indeed immediately."

His White House Physician was Ronny Jackson.
