Former Rep. John Dingell (D-Mich.), who was the longest-serving member in the history of Congress, died Thursday at the age of 92, reports the Detroit News.

Dingell was elected to the House in 1955 at the age of 29, and retired in 2014. His wife, Rep. Debbie Dingell, revealed on Wednesday that the former congressman had been receiving hospice care. Dingell tweeted on Wednesday evening: "The Lovely Deborah is insisting I rest and stay off here, but after long negotiations we've worked out a deal where she'll keep up with Twitter for me as I dictate the messages. I want to thank you all for your incredibly kind words and prayers. You're not done with me just yet.
