The Arizona GOP's Maricopa County audit: What to know about it

More than six months after his defeat in the November election, former President Trump is still claiming victory, calling the election "the big lie," despite several recounts and dozens of unsuccessful lawsuits that say otherwise.

Although every state has certified its results, the Republican-controlled state Senate in Arizona has undertaken a full hand recount and audit of the ballots and voting machines in Maricopa, the state's largest county, a move that has been frequently praised by the former president. President Biden won the county, a longtime Republican stronghold, by 45,109 votes, and he won the state by 10,457 votes. At the same time, Democrats also picked up a U.S. Senate seat from Arizona.  By subpoena, the state Senate took possession of 2.1 million ballots and nearly 400 election machines and turned them over to be audited by companies that include one whose CEO promoted debunked election fraud theories after the election. The majority-Republican county board of supervisors vehemently objected to the action and pointed to the multiple audits of ballots and machines that Arizona had already completed that had found no issues.
