The White House doctor on Tuesday criticized other physicians and politicians who have raised questions about President Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE's mental fitness for office, labeling the speculation "tabloid psychiatry."

Navy Rear Adm. Dr. Ronny Jackson, who has examined the past three presidents, told reporters Tuesday that he gave Trump a cognitive test during his recent physical, on which he said the president performed well. Based on those results, Jackson said the test showed "no indication" that Trump has any cognitive issues.

Some Democratic lawmakers have openly mused about Trump's mental fitness for office, with a group reportedly receiving a briefing by a psychiatrist recently to discuss the topic.

Jackson said that those concerns played a role in Trump's request to include a cognitive test in his physical.

"People shouldn't be making those kind of assessments about the president unless they have the opportunity to get to know him and examine him. In my opinion, that’s just tabloid psychiatry," he said. "I’m not going to address it.”

Jackson said he performed the Montreal Cognitive Assessment on Trump, which tests for diseases like Alzheimer's. Trump scored a 30 out of 30 on that test, Jackson said.

Trump's physical showed that he is largely in good health, according to the president's physician.

Trump does suffer from high cholesterol and is overweight, which is why Jackson said he's recommending changes to Trump's diet as well as an exercise plan. Jackson also said he plans to up the president's dosage of a medication meant to lower his cholesterol.
