It’s always been an odd argument to make: A 68-year-old woman running for president with blood clots who suffered a concussion in recent years isn't allowed to have her medical condition questioned or even broached.

To do so, critics, especially those on CNN and CNN.com, said would be engaging in peddling conspiracy theories.

Enter Dr. David Scheiner, a former physician to President Barack Obama, on CNN's "Erin Burnett OutFront" on Tuesday night who had the audacity to raise a number of questions around both the health of Hillary Clinton and Donald Trump, and the transparency surrounding it.

"There are a number of questions I have," said Scheiner, who was the president's physician for 21 years. "First of all, she's also 68 years old, and while I think that letter was well-written and very professional, unlike Dr Bornstein's (Donald Trump's doctor), it's not enough.

"For example, she's on Coumadin, a medication to prevent blood clots," he continued. "You have to monitor that and it says she's being monitored regularly, I'd like to know how well she's being controlled. That's a difficult drug to use."

Clinton's last released a letter from her internist in July 2015. Her campaign has vowed not to release anything else related to her medical records before Election Day.

"Also, I think she should have had a neurological examination, a thorough neurological examination in 2016," recommended Scheiner. "We know what happens to football players who have had concussions, how they begin to lose some of their cognitive ability, I think both of them (Trump and Clinton) should release their records." http://thehill.com/blogs/pundits-blog/media/293921-media-reports-on-hillarys-health-a-conspiracy-or-legitimate
