Arizona's assistant attorney general has written the state Senate asking that leaders provide materials from the recent election audit in Maricopa County.
The office says its Elections Integrity Unit will be conducting a "thorough review" of the information contained in the materials.
The letter also states that the Elections Integrity Unit previously asked Maricopa County officials to preserve all potentially relevant materials, and will be offering them a chance to provide rebuttal evidence.
According to official results, Joe Biden won the Arizona by fewer than 11,000 votes.
The recently-completed audit flagged more than 57,000 ballots in the one county alone.
Critics of the audit effort mounted by Republicans insisted it was not a fair process and that the results could be trusted. When the audit was completed, many in the media falsely reported that it proved Biden had won the election fair and square, and many one-time critics heralded the results.
In fact, although a hand recount was within a few hundred votes of the original count, that mechanism did not address the thousands of anomalies found.
Observers point out that just because there may have been tens of thousands of improper or invalid votes doesn't mean all of them would have or should have gone to or been taken away from one candidate.
