The California Republican Party is distributing unofficial ballot drop-off boxes across the state, and Secretary of State Alex Padilla said in a statement the boxes are not only misleading to voters but illegal.

“My office is coordinating with local officials to address the multiple reports of unauthorized ballot drop boxes,” Padilla said. “Californians should only use official ballot drop boxes that have been deployed and secured by their county elections office. Official ballot drop boxes and drop off locations can be found at caearlyvoting.sos.ca.gov.”

The collection boxes have been spotted at local political party offices, candidate headquarters and churches, Padilla said. CBS Los Angeles reported on a gray metal container with a taped sign reading “Official Ballot Drop Box” outside of Freedom’s Way Baptist Church in north L.A. County. The Orange County Register discovered a list of “secure” ballot boxes posted by the Fresno County Republic Party are all unofficial, including ones listed at its own headquarters and several gun shops.

Padilla offered advice to voters, reminding them that there are multiple secure options in every region.

“Ballots can be returned by mail, to any in-person voting location, or to an official secure drop box,” Padilla said. “Never hand your ballot over to someone you don’t trust. Official county drop boxes are built with specific security protections, and ballots are retrieved only by designated county personnel.”
