Democrat John Conyers is a step closer to his 26th term in Congress.
Conyers defeated Detroit pastor the Rev. Horace Sheffield III in Tuesday's Democratic primary.
The 85-year-old Conyers has been in Congress since 1965 and is in line to be the longest serving member of the House with the retirement this year of fellow Michigan Representative John Dingell.
Sheffield had challenged Conyers' name being added to the primary ballot after it was learned two people gathering signatures were not registered to vote in Wayne County.
A review found Conyers more than 400 signatures short of the 1,000 needed after the signatures collected by those workers were tossed. Michigan's secretary of state agreed. Conyers appealed and a federal judge in May ordered that his name be placed on the ballot.
