Former Republican presidential candidate and neurosurgeon Ben Carson said that both Hillary Clinton and Donald Trump should release their medical records because they are "elderly."

"I think that somebody who is running for president of the United States, particularly if they're elderly — and that would include both major candidates — should disclose their medical history," the Trump surrogate said MSNBC Wednesday.

"It's common sense. It makes sense. Because as people get older, things begin to happen to them," he added.

Trump and his allies, including former New York City Mayor Rudy Giuliani, have insisted that Clinton's physical and mental health are both failing.

When asked about Giuliani's comments that people should "go online and put down 'Hillary Clinton illness,'" and what his diagnosis of the Democratic nominee would be, Carson deflected.

"My diagnosis would be that anybody who is elderly should expose their records and we the people should know what they are," Carson explained. "Because it's a very stressful job — it's not an eight hour a day job, it's 24/7, and we need to make sure that it's taken care of."

Asked if Trump should be held to that standard, Carson responded: "Absolutely, without question."

Clinton is 68, and Trump is 70.
