Hillary Clinton reportedly suffered a concussion in December 2012 when she fell at home and hit her head.

A prominent New York ophthalmologist said the special pair of glasses she wore during Benghazi testimony in early 2013 are the type used to treat the double vision sometimes caused by severe head trauma.

Hillary Clinton adviser Philippe Reines at the State Department contacted the NFL Commissioner in 2012 to inquire about severe head injuries.

Hillary Clinton thanked Reines and added, “Having a cracked head is no fun at all.”

The email was sent on December 24, 2012.
