Cast member from 'The Good Doctor' launches bid to become Michigan's first Black senator

Actor Hill Harper, who is best known for his role on "The Good Doctor," announced Monday that he'd seek the Democratic nomination for Michigan's open seat. 

Harper, a first-time candidate who would be the Wolverine State's first Black senator, faces a difficult primary against Rep. Elissa Slotkin, who has spent months as the frontrunner to succeed retiring Sen. Debbie Stabenow. The field also includes Michigan State Board of Education President Pamela Pugh, and former state Rep. Leslie Love, who would each be the first Black woman to represent the state in the upper chamber. Republicans have yet to draw a prominent candidate for this longtime swing state, though Time's Mini Racker recently reported that John Tuttle, an executive with the New York Stock Exchange, "is likely" to announce this month.
