Roy Moore on Wednesday filed an election challenge alleging voter fraud, hoping to block Alabama from certifying the results of the vote he narrowly lost to Senator-elect Doug Jones. Moore, a Republican former state Supreme Court chief justice, has refused to concede even though Jones, a Democrat, won by more than 20,000 votes. Alabama Secretary of State John Merrill is expected to certify the result on Thursday, but the Moore campaign filed a last-minute complaint calling for a delay to allow a "thorough investigation" into possible fraud, including claims that people from other states were allowed to vote. Merrill has said it was "highly unlikely" anything would prevent Jones from being certified as the winner of the special election.
