Thousands of ballots in Westchester County could not be scanned on Election Day, ABC7 New York reports. The county now plans to count them on Wednesday.

The county elections board and the candidates agreed on how to move and count the ballots, ABC7 says. A judge signed off on the plan Tuesday night.

After polls closed, the ballots were moved under police watch to the county elections board site in Ardsley, the Rye Record reports. Voters had put them in orange emergency bags. Police will guard them until the count starts.

“The ballot scanner issues experienced across Westchester County today were serious,” the county board said in a statement, the Rye Record reports. The board said every ballot cast had been secured.

The problem hit the race for New York's 17th District. Republican Mike Lawler conceded to Democrat Cait Conley on Tuesday night, ABC7 and Gothamist report.

“I called my opponent, Cait Conley, and offered my congratulations to her,” Lawler said, ABC7 reports. He said the Westchester count would make it clear that he fell short.

The Associated Press had not called the race by late Tuesday, Gothamist reports. The final totals will come only after the Westchester ballots are counted.

The cause is not yet settled. The state elections board said some scanners did not get a needed programming update, Gothamist reports. County official Tajian Nelson said they were still looking at whether it was a printer error or a programming error, ABC7 reports.

Republican commissioner Douglas Colety said nothing nefarious had happened, ABC7 reports.

What we know: Westchester plans to count its emergency ballots on Wednesday, and Lawler has conceded to Conley.
What we don't: The final vote count, and the exact cause of the scanner failure.
