From the Washington Post:

Rep. John D. Dingell (D-Mich.) will retire at the end of his current term, capping a historic career as the longest-serving member of Congress in history.

Dingell told the Detroit News for a story published Monday morning. "I donít want people to say I stayed too long."

Dingell, 87, has served in the House for nearly 60 years. He became the longest-serving member of Congress last summer.
"I donít want people to say I stayed too long." It seems a little late for that to me.
