President Donald Trump, the oldest man to be inaugurated as president, visited Walter Reed National Military Medical Center for a physical Friday, the first of his new administration and one that he said included cardiology and cognitive tests.

Trump, 78, said Friday evening that the results would be released Sunday.

“I don’t know what to tell you other than I got every answer right,” he said.

“Overall, I felt I was in very good shape,” Trump said. “Good heart. A good soul. Very good soul.” He then mocked his immediate predecessor, Joe Biden, whose mental acuity he has long attacked, saying he “wanted to be a little different than Biden.”

The physical could offer the first glimpse of the health of Trump, who has often been guarded about even the most basic medical information since he was shot in an assassination attempt at a campaign rally in July. He has long been phobic about germs and disease. According to many of his former presidential and business aides, Trump has tried to avoid ever appearing sick.

In 2015, his personal physician at the time, Dr. Harold Bornstein, wrote in a note to the news media that Trump, then a presidential candidate, had “extraordinary” strength and stamina. Bornstein told CNN in 2018 that Trump had personally dictated the letter.

That year, the White House physician at the time, Dr. Ronny Jackson, said that Trump had a calcium score of 133, indicating plaque in his arteries but at a level fairly common for a man of his age. But the president at times has offered few details about his health. He went for an unexplained visit to Walter Reed in 2019; aides said after his term ended that it was for a colonoscopy.
