Jill Stein, the Green Party’s presidential candidate, filed a petition for a recount in Michigan on Wednesday, after a state board overseeing election results certified that Donald Trump won the state’s race by 10,704 votes, or a margin of just 0.22 percent of the 4.7 million votes cast. The Greens paid a $973,250 filing fee for a recount that is expected to start on Friday.
