The 79-year-old president spent more than three hours at Walter Reed National Military Medical Centre for what the White House described as preventive medical and dental checkups.

As Donald Trump approaches his 80th birthday, his upcoming medical exam at Walter Reed renews public focus on his health and fitness for office.

Trump has repeatedly been spotted with makeup covering bruises on his hands in recent months.

Trump will undergo his annual routine medical and dental examination at Walter Reed on Tuesday.
