Former White House physician Ronny Jackson, who served in the role under the Obama and Trump administrations, slammed President Joe Biden during an interview this week on the subject of the president’s mental fitness for office.

“I’m not trying to make a diagnosis,” said Jackson, “but I think the whole world sees that he’s having some issues. He’s struggling cognitively. It’s not a good time to have a commander-in-chief and a head of state that’s having these particular issues. I think there’s something going on … it’s a national security issue at this particular point.”

When asked by John Hines of OAN if there were “national security implications” involved, Jackson responded, “Well sure, look at what’s going on … In that position, if you have cognitive issues, it’s going to be a national security issue regardless.”
