New York: US President Donald Trump is in "excellent health," according to presidential physician, Rear Admiral Ronny Jackson, who examined him on Friday after a week of fresh questions about whether the 71-year-old commander in chief was mentally fit for office.

"The President's physical exam today at Walter Reed National Military Medical Centre in Maryland went exceptionally well," Jackson said in a statement. "The President is in excellent health and I look forward to briefing some of the details on Tuesday."

White House spokesman Hogan Gidley said that Trump wouldn't undergo a psychiatric exam as part of the physical. And what information is disclosed will be up to Trump, since federal health privacy laws cover presidents.

Jackson will take questions from reporters on the issue on Tuesday, White House press secretary Sarah Huckabee Sanders said.
