In the interview, Dr. Jackson admitted that he had not been aggressive in calling in favors, especially from the president. “He had so much on his plate. He was going through impeachment,” Dr. Jackson said. “I thought, I’m not going to put ‘Ronny Jackson in the 13th Congressional District’ on his plate.”

If he wins the seat, Dr. Jackson will be back on a government salary. If he loses, he said, he plans to make enough money to buy his wife any house in Amarillo she wants…

During his infamous news conference, Mr. Jackson said his goal was to help Mr. Trump lose 10 to 15 pounds and that he planned to bring an exercise bike or elliptical machine into the White House residence.

Mr. Jackson said those plans never came to pass. (Mr. Trump had gained four pounds by his following physical.) “The exercise stuff never took off as much as I wanted it to,” he said. “But we were working on his diet. We were making the ice cream less accessible, we were putting cauliflower into the mashed potatoes.”
