NEWPORT NEWS, Va. (AP) — Virginia’s top elections official says an unknown number of voters who may have cast a ballot in a tied Virginia House race that was decided by drawing lots were assigned to the wrong district.

The Daily Press reports a state Department of Elections review of registrations after the November election found a discrepancy between some Newport News voters’ addresses and the House district in which they were recorded as living.

Department Commissioner Chris Piper said the discrepancy has been corrected. He didn’t give a number of voters possibly affected.

The city’s electoral board chairman says he and the board are investigating.

The 94th District race between Republican David Yancey and Democrat Shelly Simonds was ultimately decided by a drawing of lots that captured national attention. Yancey eventually won the election.
