A letter from Donald Trump's former New York physician released by his campaign in 2015 declaring he would be "the healthiest individual ever elected to the presidency" was composed by the candidate himself, the doctor says.
"He dictated that whole letter. I didn't write that letter," Dr Harold Bornstein has told CNN.
Dr Bornstein was not immediately available to comment, but in a subsequent interview with NBC News he confirmed the account.
"Mr Trump has had a recent complete medical examination that showed only positive results," said the letter signed by Dr Bornstein, who said he had treated Trump since 1980.
"Actually, his blood pressure, 110/65, and laboratory results were astonishingly excellent. His physical strength and stamina are extraordinary," the letter said.
"If elected, Mr Trump, I can state unequivocally, will be the healthiest individual ever elected to the presidency."
Dr Bornstein told NBC News the characterisation of "healthiest" was "black humour."
Trump read out the language as Dr Bornstein and his wife were driving across Central Park, the doctor told CNN. The campaign released the letter in December 2015.
"(Trump) dictated the letter and I would tell him what he couldn't put in there," he said.
Dr Bornstein had previously said he had written the letter in a rush while seeing other patients.
His latest version of the letter's origins follows his accusation that Trump's ex-bodyguard Keith Schiller raided his office while retrieving Trump's medical records after he was elected president.
White House spokeswoman Sarah Sanders told reporters on Tuesday that the records were retrieved as part of "standard operating procedure."
"As is standard operating procedure for a new president, the White House Medical Unit took possession of the president's medical records," she told a regular news briefing.
Asked if the operation was a raid, she said: "No, that is not my understanding."
Trump's medical records taken in 'raid'
Dr Bornstein said a "raid" took place in February, two days after The New York Times quoted the physician as saying he had prescribed Trump a hair growth medicine for years.
"They must have been here for 25 or 30 minutes. It created a lot of chaos," Bornstein told NBC, saying the incident made him feel "raped, frightened and sad."
He identified Trump's aides as longtime personal bodyguard Keith Schiller, who until September 2017 worked at the White House as operations director; Alan Garten, a lawyer from the Trump Organisation family real-estate firm; and an unidentified third man.
Dr Bornstein said the original and only copy of Trump's charts, including lab reports under the president's name and various pseudonyms, were taken.
But the White House downplayed the incident as "standard."
"It would be standard procedure for the president, a newly collected president's medical records to be in possession by the White House Medical Unit and that was what was taking place," spokeswoman Sarah Sanders told reporters, insisting that what happened was not a raid.

Dr David Scheiner, former physician to President Obama, said he sent copies of the then-president's health records to the White House, but ensured he kept the originals.
Dr Bornstein said he was not given a form authorising the release of the records and signed by the president - known as a HIPAA release - which is a violation of patient privacy law, NBC reported.
Bornstein said that Trump dropped him after the Times article appeared.
"I couldn't believe anybody was making a big deal out of a drug to grow his hair," he told NBC. "It certainly was not a breach of medical trust to tell somebody they take Propecia to grow their hair."
NBC said the 70-year-old Bornstein was Trump's personal doctor for more than 35 years.
