The Republicans running for their party's presidential nomination say they will release their medical records if they are picked.
Ron Paul is the 76-year-old congressman from Texas. He was asked Monday if he would release his health records given he would be the nation's oldest president if he wins. Paul says he will and then challenged his younger rivals to a 25-mile bike ride.
Newt Gingrich, Mitt Romney and Rick Santorum all say they also will release their records. Gingrich joked that he has watched Paul campaign and says Paul is "in great shape."
Paul chided moderator Wolf Blitzer for the question. He says there are laws against age discrimination.
