A second member of the Conyers family has filed papers in Michigan to seek the U.S. House seat recently vacated by longtime Democratic lawmaker John Conyers.

On Wednesday, Conyers’ 27-year-old son, John Conyers III, registered his intentions to run for Michigan’s 13th Congressional District seat, the Detroit News reported.

The filing came just five days after the elder Conyers’ grand-nephew, Michigan state Sen. Ian Conyers, 29, filed to run for the same seat.

Party primaries will be held in August, with the special election to fill the remainder of the elder Conyers’ term set for November.

The elder Conyers, 88, resigned in December amid sexual harassment allegations. He cited health reasons in leaving the post he had held since 1964.

Conyers III, meanwhile, has denied accusations of domestic violence made against him in February, when he was arrested by Los Angeles police, the Detroit News reported.

Prosecutors ultimately declined to pursue charges against Conyers III, citing a lack of third-party witnesses to corroborate a woman’s claims against him, the newspaper reported.

Democratic state Sen. Coleman Young II and attorney Michael Gilmore already have announced plans to run for the 13th District seat.
