The top executive in Frio County, home to about 18,000 residents, a county elections worker and a local resident were also among those indicted on May 1, Paxton said Wednesday. The charges expand an investigation that included raids last year on the homes of Latino campaign volunteers near San Antonio, including an 87-year-old woman, although none of them have been indicted.

Most of the six are charged with what is known in Texas as vote harvesting, a felony that often involves payment for collecting and dropping off other people’s absentee ballots. Several of the officials indicted in Frio County are accused of using Cash App to pay for vote harvesting services.

The League of United Latin American Citizens last year called for a federal investigation into Texas authorities after its members’ homes were raided. No charges have been filed against any targets of those searches, according to spokesperson David Cruz, and the organization said it had not made decisions on whether to represent those who were indicted.
