VALPARAISO, Ind. (AP) — Officials in a northwestern Indiana county plagued by vote counting delays are asking the FBI to investigate alleged violations of state election law.

Porter County’s commissioners asked the FBI on Wednesday to investigate “scores of alleged violations of Indiana Election Law submitted by poll workers, voters and the public” that the commissioners had received.

The county hasn’t reported any Election Day results due to an array of problems on Tuesday, including the need for 12 county polling sites to stay open late Tuesday after those sites failed to open on time.

Vote counting didn’t get underway until Wednesday morning, more than 15 hours after the first polling places closed. It’s unclear when that work would be completed.

The situation is delaying final election results in three state legislative races.
