Doc Wrote Letter Praising Trump's Health in 5 Minutes While Trump's limo waited By Michael Harthorne, Newser Staff Posted Aug 26, 2016 6:44 PM CDT 319 comments Comments Donald Trump's doctor says he wrote his hyperbolic letter about the candidate's health in five minutes while Trump's limo waited. (AP Photo/Gerald Herbert) (Newser) – Donald Trump "will be the healthiest individual ever elected to the presidency," Trump's doctor of 35 years wrote in a letter in December. Now in an interview with NBC News, Dr. Harold Bornstein admits he wrote the four-paragraph letter in just five minutes while Trump's limo waited for him to finish. Bornstein says he didn't even stop to proofread it. That could explain multiple errors in the letter, including opening with "To Whom My Concerns," Politico reports. Regardless, Bornstein stands by his diagnosis. "His health is excellent, especially his mental health," he tells NBC (though Politico points out Bornstein is a gastroenterologist with no apparent psychiatry or psychology license). Bornstein's letter raised eyebrows in December for describing Trump's lab results as "astonishingly excellent" and stating his "physical strength and stamina are extraordinary." Bornstein tells NBC he thinks Trump's way of speaking rubbed off on him when he wrote the letter. "Clearly, Trump's hyperbole is itself a disease—and it's contagious," the Washington Post quips. Asked about his claim that Trump would be the healthiest person elected president, Bornstein points out that all the other presidents "are either sick or dead." The letter is the only medical information released by the Trump campaign. Trump and his supporters have been recently attacking Hillary Clinton over her health.
