Rep. John Dingell (D-Mich.), the longest-serving lawmaker in congressional history, has been admitted to a Detroit hospital after suffering from stomach pain.
A statement from his office says that Dingell "is doing well, is receiving an IV treatment of antibiotics, and remains in good spirits. Doctors expect him to be released in a few days, and Dingell expects to be in Washington for Congressional session next week."
Later Monday, Dingell responded to well wishers on Twitter by saying that he was "Feeling pretty good for an old Polish lawyer from Detroit."
Dingell, 88, has served the Detroit area in Congress since 1955. He announced plans to retire last year and his wife, Democratic strategist Debbie Dingell, is expected to easily win the race to succeed him.
