Bruce Bartman, a 70-year-old from Delaware County, Pennsylvania, has been charged with voter fraud.
He pretended to be his dead mom to vote for President Donald Trump in the 2020 election and registered his dead mother-in-law to vote, prosecutors said.
Prosecutors said it was the only voter-fraud case they found after hundreds of tips.
Voter fraud is extremely rare in the US, but Republicans have claimed it's a major problem and sought to pass laws restricting voting.
