Her “health and age is fair game,” Priebus said during an appearance on NBC’s “Meet the Press” on Sunday.

Last week, Republican strategist Karl Rove said Clinton’s 2012 head injury should be a factor in determining whether she runs for president in 2016.

People asked similar questions of President Ronald Reagan and Sen. John McCain (R-Ariz.) when they ran for president, so asking those questions of Clinton is fair, Priebus said Sunday.

He declined to speculate on the condition of Clinton’s health.

“I’m not a doctor. What I do know is that the issue is going to come up,” he said.

Priebus pushed back on the idea that Republicans are using questions about her health and age to keep Clinton from running.

“It’s not the mission,” he said.
