"He's very sharp. He's very articulate when he speaks to me", Jackson said.
Sanders noted that Jackson is the only doctor that has examined Trump and is "the only credible source when it comes to diagnosing any health concerns".
The results were something the White House ― which had refused to say beforehand whether Trump would take a cognitive assessment ― was pleased to discuss, and Jackson spent almost a full hour taking questions about Trump's physical exam at Tuesday's daily briefing.
"He's more enthusiastic about the diet part than the exercise part, but we're gonna do both", said Jackson.
Even more perplexing for Colbert is that "despite all evidence, Donald Trump does have a heart".
According to Jackson, Trump weighs 239 pounds and is 6 feet, 3 inches tall. "I think a reasonable goal over the next year or so is to lose 10 to 15 pounds".
Aside from his weight, Trump's cardiac health is excellent for his age (Trump is the oldest President to ever assume office). Jackson acknowledged he had spoken with the president about "diet, exercise and weight loss", and said a nutritionist would be working with the president to change his eating habits.
The doctor speculates that Trump requested the exam in an attempt to beat back the narrative of the past few weeks that he is mentally unfit for office. "He has incredible genes, I just assume".
"It's called genetics", Jackson said.
"You said he doesn't drink and he doesn't smoke and other than the diet issue-did you address drug addiction?" the reporter asked.
The test, created in 1996 by neurologist Ziad Nasreddine in Montreal, isn't a psychiatric exam, Dr. Jackson acknowledged, and it isn't meant to screen for mental health issues beyond cognitive troubles.
On The Daily Show that night, Noah launched into a monologue about the physical examination and joked that maybe we were all wrong about Trump's personal doctor, Dr. Harold Bornstein.
The public report from Trump's upcoming exam was also likely to be short and sweet, said George Annas, head of the Center for Health Law, Ethics and Human Rights at Boston University School of Public Health.
Cognitive testing looks for signs of mild cognitive impairment and/or Alzheimer's disease.
'The people that do the food at the White House are extraordinary, but I think they can maybe make the portions a little bit smaller and maybe we'll cut out some of the more fattening ingredients, ' he said.
