Former Rep. John Dingell, known for his lengthy service in the lower chamber and his pithy quips on Twitter, promised to stay in contact with his supporters via the platform Wednesday after moving into hospice care.

The Michigan Democrat, 92, is the longest-serving member of Congress, having first been elected to represent an Ann Arbor-area district in 1955. He succeeded his father John Dingell Sr., and his wife, Rep. Debbie Dingell, won the race to replace him after he stepped down in 2015.
