Dr. Ben Carson called on former Secretary of State Hillary Clinton to release a specialized MRI Monday a day after she became “overheated” and stumbled while leaving an event commemorating the 15th anniversary of the 9/11 attacks.

The former presidential candidate and adviser to Donald Trump told BuzzFeed that while the MRI would be helpful in the case of Clinton due to the concussion she suffered in 2012. He said both candidates should release “detailed” medical records.
