Donald Trump undertook a three hour-long medical examination last week, following questions about the president's health and cognitive ability.
Donald Trump's doctor has described the US President's cognitive ability as "normal".
It follows a three hour medical examination last week, his first since entering the White House. He was examined by military doctors at the Walter Reed Medical Center in Bethesda, Maryland, in tests that were said to have gone "exceptionally well".
There have been concerns Trump's mental health has deteriorated during his time in office.
Dr Ronny Jackson, the White House Physician, said; "The President is mentally very sharp and very intact. He is absolutely fit for duty. I think he will remain fit for duty for the remainder of this term and even for the remainder of another term if he's elected."
Last week's publication of 'Fire and Fury: Inside the Trump White House' reignited the debate about the 71 year old's health.
Author Michael Wolff alleged Trump is intellectually and mentally incapable of carrying out his role and is even described as a child by staff.
The US President has since dismissed the book's claims, saying they're full of lies and Wolff had zero access to him.
When asked by a reporter how a man who consumes fried chicken and Diet Coke and does not exercise could be in good shape, Dr Jackson replied: "It's called genetics. He has incredible genes."
However, Dr Jackson added that Mr Trump could benefit from a lower-fat diet and more exercise.
