Leaders of the U.S. House of Representatives and Senate will hold a celebration to recognize Rep. John D. Dingell as the longest-serving Member in the history of the United States Congress on Thursday, June 13, at 3:30 P.M. EST in National Statuary Hall of the United States Capitol.
The 86-year-old was first elected in 1955. He says his accomplishments in office mean more to him than the record.
"Just remember what my dad said, 'It isn't how long. It's how well,'" Dingell said.
Dingell said he and his wife Debbie will begin weighing the decision of running again this January.
His longevity record eclipses that of the late Sen. Robert Byrd of West Virginia.
