According to the District Attorney's Office, Galvan and Dawson, a former Compton City Council candidate, conspired to secure votes for Galvan to ensure he retained his District 2 seat on the panel. Prosecutors also contend Galvan tried to bribe a county registrar employee as she was counting ballots on election night.
The other four defendants allegedly registered to vote at Dawson's address in Compton, even though they didn't live there, prosecutors said. They are all accused of voting illegally in the election.
Galvan defeated challenger Andre Spicer 855 to 854.
Galvan and Dawson are expected to be arraigned Friday in downtown Los Angeles. Court dates have not yet been set for the other defendants.
"Elections are the cornerstone of our democratic nation," District Attorney George Gascon said in a statement.
