Dr. Ronny Jackson began serving as the White House physician to Barack
Obama back in 2013. When Donald Trump took office in 2017, Jackson remained in the position.
The doctor first became known to the American public due to comments made about the condition of the clearly unhealthy Donald Trump. “He has incredibly good genes, and it’s just the way God made him,” Jackson said. “I told the President that if he had a healthier diet over the last 20 years he might live to be 200 years old.”
