They both were patients of very unprofessional doctors:
Trump's:
First doctor was Harold Bornstein who once authored a note that stated "If elected, Mr. Trump, I can state unequivocally, will be the healthiest individual elected to the presidency . . . and laboratory test results were astonishingly excellent." He later admitted that Trump had "dictated that whole letter. I didn’t write that letter”.
A month after the election, Bornstein seemed relatively unfazed by the prospect of the new president — who, at 70, would become the oldest person to ever assume the office — dying on the job. “If something happens to him, then it happens to him,” he told Stat News at the time. “It’s like all the rest of us, no? That’s why we have a vice president and a speaker of the House and a whole line of people. They can just keep dying.” - Politico, Jan 14, 2021
Borstein later accused Keith Schiller¹ — the former White House director of Oval Office operations and Trump’s longtime personal bodyguard — of conducting a “raid” of his office the previous year to obtain the president’s medical records.
Next doctor was Ronny Jackson who the Department of Defense Office of Inspector General concluded, by a preponderance of the evidence, had "made sexual and denigrating statements about one of his female medical subordinates to another of his subordinates"; that Jackson "drank alcohol with his subordinates in Manila, became intoxicated, and, while in his hotel room, engaged in behavior that witnesses described as screaming and yelling, and behavior that some complained might wake the President". He was also described by some as "a human gumball dispenser". Subsequently demoted by Trump.
Final doctor was Sean Conley who subsequently prescribed hydroxychloroquine to Trump even though it had been thoroughly discredited as a Covid-19 prophylactic. After Trump then became infected with Covid-19, Conley repeatedly lied about his condition to the public.
Note: Taking Hydroxychloroquine did not prevent Trump from being infected with Covid.
Trump's next doctor was Bruce Aronwald, D.O. who on Nov 20, 2023 stated "overall health is excellent . . . [Trump's] physical exams were well within the normal range and his cognitive exams were exceptional . . . he will continue to enjoy a healthy active lifestyle for years to come."
Dr. Aronwald did not release any medical records.
Hitler's:
Personal physician was Theodor Morell who according to his own medical log administered Hitler with over 92 different compounds which included varying forms of heroin, cocaine, testosterone, amphetamines, caffeine, and strychnine. He was also grossly obese and suffered from poor personal hygiene and body odor.
Of the 92 different medications prescribed for Hitler during the war years, 20 were manufactured by firms owned by Morell. Some of them were used on Hitler before being scientifically tested.
Morell used leeches twice to treat Hitler`s borderline high blood pressure. - Chicago Tribune, Oct 14, 1985
Escort doctor was Karl Brandt (starting in August 1934). A member of Hitler's inner circle at the Berghof (see The Residence), he was selected by Philipp Bouhler, the head of Hitler's Chancellery, to administer the Aktion T4 euthanasia program. Brandt was later appointed the Reich Commissioner of Sanitation and Health. Accused of involvement in human experimentation and other war crimes, Brandt was indicted in late 1946 and faced trial before a U.S. military tribunal along in United States of America v. Karl Brandt, et al. He was convicted, sentenced to death, and later hanged on 2 June 1948.
"He was the White House doctor. He was a great doctor. He was an admiral, a doctor, and now he's a congressman," 'I said, 'which is the best if you had your choice?' and he sort of indicated doctor because he loved looking at my body. It was so strong and powerful, but he said I'm the healthiest president that ever lived."
