MIAMI (CNN) - Sen. John McCain on Monday dismissed concerns about his age raised by action-film star Chuck Norris, former Arkansas Gov. Mike Huckabee's most famous backer.
Norris, who has cut tongue-in-cheek campaign ads for Huckabee, told reporters at his Texas ranch Sunday that serving as president accelerates the aging process 3-to-1.
"If John takes over the presidency at 72 and he ages 3-to-1, how old will he be in four years?" Norris asked as Huckabee looked on. "Eighty-four years old - and can he handle that kind of pressure in that job?"
McCain sighed theatrically when asked about that remark Monday.
"I'm afraid I may have to send my 95-year-old mother and wash Chuck's mouth out with soap," he said.
McCain, who won Saturday's Republican primary in South Carolina, was on the stump in south Florida.
