David Walker runs the Comeback America Initiative, or CAI, a nonprofit that raises awareness about the government's growing debt. He served as U.S. comptroller general from 1998 to 2008. The comptroller runs the Government Accountability Office, an agency that works for Congress and evaluates how the government spends taxpayer money.
NAME: David Walker
AGE: 61. He was born on the same day as the rock star Sting. "Which is not a bad nickname for comptroller general. We're stinging people all the time."
WHAT'S NEXT: CAI will release a report on the state of the federal government's debt and what to do about it on Sept. 17. The group will discontinue operations three days later, partly because of a promise Walker made to his wife to cut back on work, and partly because he's not sure politicians are willing to seriously tackle the debt problem. He says he'll stay involved in political reform advocacy but isn't sure how.
WHERE HE'S FROM: Born in Alabama (he cheers for Crimson Tide football), raised in Alabama and Florida (his first job was delivering papers for the afternoon Miami News), and now lives in Bridgeport, Conn.
FAMILY: He met his wife, the former Mary Etheredge, at the University of Maryland's Cole Field House. Both were students at Jacksonville University in Florida and were in town to watch the school's basketball team in the Final Four. They have one son, one daughter and three grandchildren.
WHY HE WEARS A PIN THAT SAYS "CPA": It was a gift when he was awarded the Gold Medal for Distinguished Service from the American Institute of Certified Public Accountants. It came with a gold medal, too, which he keeps in a safe deposit box. He's also in the Accounting Hall of Fame at Ohio State University. "Though it's more like a hallway of fame."
