President Obama may not be willing to weigh in on Joe Biden, but his former doctor of 22-years says that Biden is not doing well.

"He's not a healthy guy," said Dr. David Scheiner, who was Obama's doctor before he became president. Scheiner says that medical records disclosed by Biden's campaign are concerning and incomplete according to the Washington Examiner.

"He’s not in bad shape for his age, but I wouldn't say he’s in outstanding health. Could I guarantee he won't have issues for the next four years? He has a lot of issues that are just sort of sitting there."

A three-page letter from Biden’s physician concluded the former vice president is a “healthy, vigorous, 77-year-old” that is fit to be president. But the letter also revealed Biden receives treatment for an irregular heartbeat and high cholesterol and that he deals with acid reflux and seasonal allergies. It noted his already known history of aneurysms and that he took blood thinners. The details from the letter made Scheiner, 81, concerned about Biden’s potential for strokes, and he said he would want to see results from an MRI or CT scan. Because Biden also used to have sleep apnea before getting surgery on his sinus and nasal passages, Scheiner said he would also like to review the results of a sleep study. -Washington Examiner

Scheiner points to a lack of an MRI despite Biden's two brain aneurysms in 1988 - the first of which was nearly fatal. The Examiner notes that they interviewed Biden's former surgeon, who says the 2020 Democratic candidate is good to go.

Also lacking from Biden's medical disclosure are details from any recent checkups which would have likely screened for future issues, while the report did include surgeries which had not previously been disclosed - such as one for an enlarged prostate.

According to Dr. Kevin O'Connor who wrote the assessment, Biden has received "multiple physical therapy treatments and surgeries, for various sports medicine and orthopedic injuries," but did not elaborate.

"I had no idea Biden had such a history. My goodness gracious, he’s got a lot of history," said Scheiner.

When Biden was Obama's running mate in 2008, his medical disclosure was 49 pages.

As the Examiner also points out, "The most recent doctor's letter doesn’t address Biden’s vision, even though Biden blamed a contact lens mishap for his eye filling with blood during a town hall, nor does the letter address whether he has had multiple cosmetic surgeries."

Historically, presidential candidates have relied on letters from their personal doctors to disclose details of their health to the public. As a result, there’s no uniform way that a candidate’s medical information is presented to voters, and there’s no guarantee the information is complete. For instance, former Arizona Republican Sen. John McCain made more than 1,500 pages of medical and psychiatric records available to reporters because he had a history of cancer and was a prisoner of war, but rumors about his health persisted. In contrast, Hillary Clinton released a two-page letter that omitted her weight. -Washington Examiner

Of course, President Trump allegedly dictated his own medical report during the 2016 campaign, when his doctor said he would be the "healthiest individual ever elected to the presidency." Scheiner says he'd love to see an MRI on Trump to check for strokes, along with a neurocognitive assessment.

"Something happened," Scheiner insists, referring to Trump's unscheduled visit to Walter Reed National Military Medical Center in Bethesda, Maryland.

"The stakes are too high," said Scheiner. "If they make a mistake because their cognitive skills are diminished, we pay the price."
