Karl Rove suggested at a conference near Los Angeles last week that Hillary ClintonHillary Diane Rodham ClintonFormer presidents, first ladies come together to honor Barbara Bush Romney: Parts of Comey book read 'too much like a novel’ Collins: Comey should have waited to release his memoir MORE might have brain damage, the New York Post reported late Monday. 

“Thirty days in the hospital? And when she reappears, she’s wearing glasses that are only for people who have traumatic brain injury? We need to know what’s up with that,” said Rove, referring to Clinton's fall in late 2012. 

Voters should have the right to information about Clinton's health history if she runs for president in 2016, he added.

Rove raised the possibility of a brain injury multiple times to the audience, according to the report. Rove was on stage with Robert Gibbs, President Obama's former press secretary, and CBS News correspondent Dan Raviv. 

“Please assure Dr. Rove she’s 100 percent,” a Clinton representative told the Post.

Clinton fell in her Washington, D.C., home in December, 2012, hit her head and was diagnosed with a concussion after suffering from a stomach virus. Doctors at the time said a blood clot had formed behind her right ear between her skull and brain.

During a Senate Foreign Relations Committee hearing on Benghazi in early 2013, Clinton testified and donned a pair of eyeglasses meant to help with lingering symptoms from the concussion.

Clinton will be 69 years old at the time of the 2016 election.
