The Department of Motor Vehicles admitted Monday a mistake caused as many as 1,500 noncitizens being registered to vote in the state.
The agency was alerted to the mistake when Randall Marquis, a Canadian citizen and legal permanent resident in the U.S., went to the Los Angeles Times to tell them about receiving a piece of mail from the DMV saying he was registered to vote.
