Arizona is the fourth state to bring charges against electors who falsely cast votes for Trump in states that President Biden won, along with Michigan, Georgia and Nevada.
New Mexico, Pennsylvania and Wisconsin are the states which have yet to indict their fraudulent electors.
Not actual electors, just Arizona Republican operatives who certified the election as "Trump Won" even though the vote count showed Biden as getting the majority of the votes. Don't know why the article refers to them as "fake electors", I don't think any of the 11 people in the indictment were the actual Arizona state electors attending the EC... but I'm not going to dig far enough to verify.
The elector would have cast Arizona's votes for the incorrect candidate based on the incorrectly certified popular vote count.
