Joe Biden's cognitive abilities and stamina have been called into question by the chief White House doctor to former President Barack Obama.
“The best way I can describe him every time I see him is that he’s just lost,” said Dr. Ronny Jackson, the former White House physician to Obama and President Donald Trump.
“I won’t make any particular diagnosis about dementia. ... But what I will say is that something is not right,” added the retired Navy rear admiral who recently won a House GOP primary in Texas.
Jackson said that he is “not comfortable” with Biden being commander in chief. “I’m not,” he said of the top Democrat, set to be nominated by the Democratic Party for president on Thursday.
