"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".

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.
