Report: Donald Trump's doctor wrote health letter in 5 minutes

NBC News reported Friday the letter from Donald Trump's doctor that declared Trump would be the "healthiest individual ever elected to the presidency" was written in five minutes as a limo waited downstairs to collect it.

In an interview from his Park Avenue office, Dr. Harold Bornstein said he hastily wrote the letter, but defended his over-the-top wording, telling NBC News that he "picked up [Trump's] kind of language" as he wrote.

"I thought about it all day, and at the end I get rushed and I get anxious when I get rushed, so I tried to get four or five lines done as fast as possible," Bornstein said of his writing process.

Bornstein's letter, released to the public in December, has again gained attention in recent days, as Trump and his surrogates have touted conspiracy theories about Hillary Clinton's health.

MSNBC's Rachel Maddow asked Trump's new campaign manager Kellyanne Conway in an interview earlier this week — after Trump pushed unsubstantiated rumors about Clinton's health — whether Trump should release a more serious health letter.

"As a doctor's letter, it's a little bit absurd. It's a non-serious letter," Maddow said, according to a transcript from MSNBC. "It's full of typos. It's hyperbolic. It's unprofessional. Most of the letter has no medical meaning."

Conway responded with a simple, "perhaps," adding that she did not want to comment on Clinton's health.
