John Conyers Jr., who represented Michigan in Congress for more than five decades, has died at the age of 90. His death was confirmed Sunday by the Wayne County Medical Examiner's Office in Detroit.
Conyers was the longest-serving African American lawmaker in congressional history, a co-founder of the Congressional Black Caucus and a fierce champion for civil rights. But he would leave office at the age of 88 amid allegations of sexual harassment.
