President Obama's Former Doctor: Independent Physicians Should Examine Candidates

— -- Now that both candidates’ personal doctors have released their reports, Jonathan Karl and Rick Klein talked to the guy who did the same for then-Senator Obama when he was the Democratic nominee in 2008.

Dr. David Scheiner, President Obama’s personal doctor for more than 22 years, said the system is biased and objective doctors should examine the candidates.

Scheiner told ABC News' "Powerhouse Politics" podcast this morning that candidates should be examined by independent doctors, not their personal physicians. He said a candidates' long-time doctors might not feel comfortable honestly assessing the health of their patients publicly.

"I think it would have been very difficult for me to put something out that was really harmful in terms of his status. I don’t know if I would have done that or not," Scheiner said.

"I would like to think I have more integrity, that I would have been honest about that," he added. "But it is a terrible position to be put in. And because it is such a terrible position I think the whole thing has to change.”

As it turned out, he said Obama’s health was excellent, so he didn't face that conflict.

Talking to ABC News White House correspondent Jonathan Karl and political director Rick Klein, he said that the military does physical and neuro-psychological evaluations of their personnel and that candidates for president should be subject to the same scrutiny.

As for the current candidates, Scheiner, who is a professor of medicine at the University of Illinois at Chicago, said he would want to know more about both candidates’ health than has already been released.

Conceding that Hillary Clinton has released more health information than Donald Trump, he still wanted to see her lying and standing blood pressure readings, since she has fainted several times. He thought she should have a neuro- psychological exam to see if her 2012 concussion caused more damage than is known.

As for Trump, Scheiner wanted to see x-rays of his feet confirming the bone spurs that got him deferred from the Vietnam War and he suggested he should have a neuro-psychological exam, as well. From what he has heard so far, Scheiner said there may be evidence of a personality disorder. "That warrants an evaluation, the kind of statements he makes." He says there might be medical issues behind the behavioral issues he sees.

He said if he were Donald Trump’s doctor he would mention his "jelly belly" and "pat him on the tummy."

Scheiner wrote an opinion article for the Washington Post earlier this month explaining why the public needs more health information about the candidates.
