Governor Branstad met wellwishers in his formal office this morning on his 7,640th day in office. That makes him the longest-serving governor in U.S. history.
Childhood friends and longtime supporters came to the open house to congratulate Branstad on the milestone.
Branstad explains his longevity this way.
"Growing up on a farm and learning to work hard at an early age," Branstad says. "I had great teachers who encouraged me to go into public service."
