A California sheriff running for governor has seized more than half a million ballots cast in a November special election from county election officials, saying he’s investigating a ballot count discrepancy.

County elections officials have disputed the claims by Riverside County Sheriff Chad Bianco, a Republican. California Attorney General Rob Bonta, a Democrat, called Bianco’s move unprecedented and says it is designed to sow distrust in elections.

Bianco held a news conference Friday saying his office had launched the investigation after receiving a complaint from a local citizens group about the ballot count from a November 2025 special election on redistricting.
