Dingell's wife, U.S. Rep. Debbie Dingell, released a statement Tuesday saying her 89-year-old husband was admitted to Henry Ford Hospital on Monday for a heart procedure. She didn't offer specifics, but said her husband was comfortable and "his usual feisty self."
The Democrat served 59 years in Congress, after being elected in 1955 to fill the House seat vacated by his father. Debbie Dingell was elected to her husband's Detroit-area seat after he decided to retire last year.
John Dingell was hospitalized in 2003, following an operation to open a blocked artery. He also spent two weeks in a Washington hospital in December because of a fractured hip.
