Rove was speculating on the aftermath of Clinton's 2012 hospitalization for a blood clot caused by a concussion she suffered in a fall. Her injury delayed her testimony before Congress on the 2012 terrorist attack in Benghazi, Libya.
But what he said "stunned" the conference, according to the report.
"Thirty days in the hospital?" Rove said at the conference, where he appeared alongside author Dan Raviv and former White House Press Secretary Robert Gibbs. "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."
According to the report, Rove repeated the suggestion multiple times at the conference.
A spokesperson for Clinton told the Post to "please assure Dr. Rove she's 100%."
"Karl Rove has deceived the country for years, but there are no words for this level of lying," the spokesperson said.
The Democratic National Committee immediately slammed Rove for his remarks, blasting out an email to reporters on the Post's story.
"It appears Karl Rove's medical diagnoses are about as solid as his election night prognostications," the committee said.
