Former U.S. Rep. John Dingell is in a Detroit-area hospital after a heart attack.
U.S. Rep. Debbie Dingell says her 92-year-old husband had a heart attack early Monday and is "alert and in good spirits, cracking jokes as usual."
She added, "We'll know more later."
John Dingell, a Democrat, was in office for nearly 60 years and still remains the longest-serving member of the House or Senate in U.S. history. He didn't run for re-election in 2014, the same year that his wife was elected to his 12th District seat in southeastern Michigan.
