"Elizabeth Edwards fought a brave battle against a terrible, ravaging disease that takes too many lives every day. She was an inspiration to all who knew her, and to those who felt they knew her. Jill and I extend our deepest sympathies to the Edwards family as they grieve during this difficult and painful time."
