text: Thank you, Representative John Dingell (MI-12), for your many years of dedicated service to our nation and the state of Michigan. Throughout his almost 60 years in Congress, Rep. Dingell advocated strongly for the environment and fought hard for AmericaÛªs auto industry. As the longest-serving member of Congress in history, Rep. DingellÛªs experience, institutional knowledge and passion will be missed. Best wishes for a happy and relaxing retirement!
