US presidential hopeful Donald Trump has handed over a one-page summary of a recent physical examination on a doctor's television show - but his campaign will not reveal what was disclosed.
Mr Trump, ever the showman, appeared on The Dr Oz Show in what was billed by his campaign as a discussion about his general well-being and his family's medical history.
However, reversing what aides had said earlier, the Republican candidate handed host Mehmet Oz one page of results from a physical conducted last week by his physician, Dr Harold Bornstein.
The show does not air until Thursday and the campaign declined to immediately disclose the results.
A statement from the show said "Dr Oz took Mr Trump though a full review", looking at his nervous system, cardiovascular health, prostate health and family medical history.
Both Mr Trump and his Democratic opponent, Hillary Clinton, have been under increased pressure to release detailed medical records, especially after Mrs Clinton was diagnosed with pneumonia and was captured on video stumbling getting into a waiting van at a 9/11 memorial ceremony on Sunday.
Dr Bornstein had previously written a note declaring that the 70-year-old Mr Trump would, if elected, be the healthiest president in history. The campaigns of both Mr Trump and Mrs Clinton, 68, have said that their candidates would be releasing detailed medical records in the coming days.
The appearance with Oz came hours before Mr Trump was to visit Flint, Michigan to condemn the government failure which led to that city's water crisis. The city's mayor made clear she did not want him to come.
It is the Republican presidential nominee's first visit to the poverty-stricken city since lead was detected in its water supply in April 2014.
He is expected to visit a water plant and a church while denouncing the crisis that affected 100,000 people after the city left Detroit's water supply and started using improperly treated Flint River water.
Mr Trump's visit to Flint, like his one last month to flood-stricken Louisiana, is bound to produce images aimed at persuading Americans that the celebrity businessman can appear presidential.
It also highlights his aims to compete in the industrial Midwest, though polls have him down in Michigan, which last went Republican in 1988.
Flint Mayor Karen Weaver, a Democrat, condemned the visit, saying the Trump campaign had not offered to help the city and his visit would be a distraction.
Flint was under state control in 2014 and Michigan's governor, Rick Snyder, a Republican, has come under scrutiny for his handling of the crisis. Mr Trump has declared Flint's water problems "a horror show" and said "this is a situation that would have never happened if I were president".
