Riverside County was among several registrar’s offices around Southern California and the nation to get bomb threats after Election Day.

Maricopa County, Arizona, which Biden won by a slim margin, has consistently been the subject of election denialism conspiracy theories. The other five — Michigan’s Wayne County, Pennsylvania’s Philadelphia County and Georgia’s DeKalb, Fulton and Gwinnett counties — were some of the largest Democratic strongholds in their respective states.

Polling places in Democratic-leaning areas of five swing states received bomb threats that officials said likely came from Russia.

Both the Registrar-Recorder headquarters and ballot processing center were swept by investigators and no threat was located.

Orange County’s elections office, where ballots were being counted, received a bomb threat Friday afternoon, the registrar said. Staff and members of the public who were watching ballots being tallied were evacuated from the Santa Ana building at about 6:45 p.

Since Americans around the country exercised their right to vote on Election Day, a couple of ballot processing centers have been forced to evacuate. In both Orange and Riverside counties, bomb threats prompted their registrar of voters to evacuate for a short period as ballot processing was taking place.
