A Pennsylvania county, which made headlines after voting machines failed to display Republican ballots during a primary election last week, voted on Tuesday to request a top prosecutor further investigate the mishap.

Luzerne County’s 11-member council voted to ask the district attorney’s office to look into a May 18 controversy where all ballots appeared as Democratic on a series of machines from Dominion Voting Systems, a company marred by dubious election fraud claims in the aftermath of the 2020 presidential election, according to the Times Leader. One member, Linda McClosky Houck, was absent at the time of voting.
