White House physician Ronny Jackson on Tuesday said the idea that President Trump has mental health issues was "tabloid psychiatry," dismissing a claim that some mental health experts are making even though they haven't examined the president.

“People shouldn’t be making those types of assessments about the president unless they’ve had the opportunity to get to know him and examine him, and in my opinion, that’s just tabloid psychiatry and I’m not going to address it or fall into responding to those kinds of questions or accusations,” Jackson told reporters during Tuesday’s White House press briefing when asked to respond to doctors who have said they believe the president shows signs of dementia.

Jackson appeared before reporters to detail the results of Trump’s medical exam, which occurred Friday at Walter Reed National Military Medical Center in Bethesda, Md.

A number of reporters inquired Tuesday about Trump’s mental state, including whether he showed symptoms of dementia. Some in the press and political pundits have questioned the president's mental health, most recently after a new tell-all book about the White House was published earlier this month.

Twenty-seven psychiatrists and mental health experts offered their assessments of Trump’s mental health in a book called The Dangerous Case of Donald Trump published last year. The book was edited by Dr. Bandy Lee, a Yale University psychiatrist, who has said the president was “going to unravel, and we are seeing the signs.”

But the American Psychiatric Association recently warned its members not to offer diagnostic opinions about public figures they haven’t examined, per a longstanding doctrine known as the “Goldwater Rule.”
