Up to 300 voting machines in Westchester County, New York, stopped accepting ballots on Tuesday, when polls opened at 6 a.m., according to CBS News.

The county board of elections attributed the failure to a programming change in a single municipality: machines elsewhere in the county kept the original programming and could not recognize the ballots being used for Election Day. County Executive Ken Jenkins said at a press conference that up to 250,000 ballots were affected, according to Newsweek. Voting continued under contingency procedures, with ballots kept under bipartisan oversight and scanned and counted after polls close in accordance with established procedures. Rep. Mike Lawler said both camps agreed to count the ballots after voting concludes, in an agreement to be submitted to a judge on Tuesday afternoon; 10 machines will be set up at the Westchester County Board of Elections headquarters, with capacity to process 2,000 ballots per hour, according to ABC7 New York. The disruption came on the day of the midterm elections, which in New York include the governor's race between Governor Kathy Hochul and Bruce Blakeman.
