If he wins, Conyers, 84, will become dean of the House for his 50 years in office, the Detroit News reported Wednesday.
In announcing his re-election candidacy, Conyers pledged to carry on the legacy of Rep. John Dingell, D-Mich., who announced his retirement Monday after 59 years in office.
"John Dingell has set the standard for honorable leadership in the United States House of Representatives," Conyers said in a statement. "His Democratic leadership will be sorely missed."
Conyers faces a primary challenge from the Rev. Horace Sheffield in Michigan's 13th Congressional District, which includes parts of Detroit and suburban Wayne County.
