The White House, which previously said Trump would not undergo a psychological exam, has called the questions being raised about Trump's mental fitness "disgraceful and laughable", and Trump himself tweeted that he is a "very stable genius". Jackson said Trump has avoided some big heart risks - he's never smoked and isn't diabetic - and has no family history of heart problems.
Last year, Trump released a clean bill of health but some pointed out that the record lacked details and had an over-the-top portrait of the president's health conditions. Jackson, a longtime White House physician, said Trump could live up to 200 years if only he watches what he eats, follows a low-fat diet, and maintains an exercise routine.
"I find no reason whatsoever to think the president has any issues whatsoever with his thought process", Jackson said. "Some people just have great genes".
Jackson said that the president is eating a healthier diet now that he is in the White House and has a team of chefs cooking for him. "He has incredible genes I just assume", Jackson said.
He said Trump asked to go under a cognitive assessment and he has "no concerns about his cognitive ability".
"All clinical data indicates that the president is now very healthy, and that he will remain so for the duration of his presidency. the president's overall health is excellent", Navy Rear Admiral Dr Ronny Jackson told reporters.
It was most noticeable at the end of his speech when he said: 'God bless the United Shhhhtates'.
Dr. Ronny Jackson, a Navy rear admiral who directs the White House medical unit, conducted Trump's annual physical last Friday.
"The president and I talked; he would like to lose 10 to 15 pounds".
According to him, it is evident that the President did not suffer from mental issues that could prevent him from functioning in office and can serve out two terms of eight years.
As for medicines, Trump now has prescriptions for Crestor, for lowering cholesterol; Aspirin; Propecia, for hair loss; Soolantra Cream for rosacea; and a multivitamin.
The president is otherwise healthy-except that, at 239 pounds and 6-feet, 3-inches-tall, he is one pound away from being categorized as obese.
He said Mr Trump is "absolutely" fit for duty, and that based on his assessment, the president would be physically fit for another term in office. "He gets up and he just starts a new day", he said.
"A cognitive screening exam using the Montreal Cognitive Assessment was normal, with a score of 30 over 30", he said.
