The chair of a Pennsylvania county election board updated voters Monday on the status of 2,500 voter registration and mail-in ballot applications that had been flagged last month as potentially fraudulent and prompted a county and statewide investigation in the crucial swing state.Speaking at a press conference, Lancaster County Commissioner Ray D’Agostino said that of the 2,500 registration and mail-in ballot applications that had been flagged as suspicious, a 57% majority had been confirmed as valid, and 17% were confirmed to be fraudulent, he said. The remaining 26% of voter registration applications and mail-in ballot applications are either incomplete or unverified,
