Trump is fit for duty

Donald Trump is expected to remain physically fit for the duration of his presidency and has "no cognitive issues whatsoever," according to full results from his first medical examination released Tuesday.

Trump's critics have openly questioned his mental health, and an explosive book on his presidency published earlier this month described aides as having doubts about his fitness for office.

"All data indicates the president is healthy and will remain so for the duration of his presidency," doctor Ronny Jackson told a White House briefing following last week's physical, which determined the 71-year-old to be in "excellent" health.

"He has incredible genes and that's the way God made him."

Jackson said Trump, who has recently faced a swirl of speculation about his mental fitness, had himself requested a cognitive test in which he performed "exceedingly well."

"I think he saw doing the physical as an opportunity to put some of that to rest," Jackson said. "And I think he wasn't the least bit concerned that he had anything to hide."

The screening was carried out using a test called the Montreal Cognitive Assessment, on which Trump scored 30/30, Jackson said.
