Washington D.C.: Longest-serving member of Congress in the history of United States, John D Dingell Jr who used his power in the House of Representatives to expose government fraud and defend the interests of his home state Michigan's automobile industry, died on February 7 at the age of 92.
A Michigan Democrat, Dingell announced in 2014 that he will not seek a 30th full term in Congress and was succeeded by his wife, Debbie Dingell, reported The Washington Post.

Debbie Dingell, D-Michigan, said in a statement as quoted by CNN.
