In Arizona in 2020, prior to the election, the parties appointed their own slate of potential electors. laws establishing the winning candidate in their state get awarded their electoral votes. By the safe harbor deadline, Arizona determined, and certified, Joe Biden as the winner of their state. Therefore, in accordance with their laws, Arizona's Secretary of State certified the Democratic slate of electors and sent that official certificate to Congress.
Republicans were sent a fake certificate to sign; which they did, attesting to the falsehood that Trump won Arizona and then sent their own uncertified fake certificate to Congress in an attempt to encourage Pence to not count Biden's real electors.
