Donald Trump s personal physician told NBC News that he wrote a now-infamous medical report about the candidate in just five minutes.

Dr. Harold Bornstein, a gastroenterologist who has been Trumps doctor for more than three decades, released a brief note last December declaring the reality TV star would be the healthiest individual ever elected to the presidency. The four-paragraph letter, which billed Trumps health as astonishingly excellent, was far less detailed than medical reports traditionally released by presidential candidates.

In an interview with NBC airing Friday, Bornstein said he spent five minutes on the letter while a car sent by Trump waited for him outside his office in Manhattan.

I get rushed and I get anxious when I get rushed, so I try to get four or five lines done as fast as possible, Bornstein explained. In a rush, I think some of those words didnt come out exactly the way they were meant.

The doctor stood by his assessment of the reality TV stars wellness.

His health is excellent, particularly his mental health, he said.

He also defended the claim that Trump would be the healthiest president in history.

I like that sentence to be quite honest with you, and all the rest of them are either sick or dead, he said.

Watch the interview above.

Bornstein and his bizarre note have come under scrutiny again as Trump and his campaign surrogates have floated conspiracy theories about Hillary Clintons health. MSNBC s Rachel Maddow pressed Trump campaign manager Kellyane Conway on the issue during an interview Thursday.

If he was elected, Donald Trump would be the oldest person to ever be sworn in as president, Maddow said. Whether or not hes going to try to make Hillary Clintons health the issue, doesnt he owe it to the American people to release an actual medical report, a more credible, more complete statement?

Conway said perhaps he should release more information.
