In Fulton County, Georgia, during the 2020 presidential election, officials admitted that over 130 tabulator tapes—receipt-like records from voting machines—were unsigned by poll workers, violating state regulations and affecting approximately 315,000 early in-person votes. Additionally, at least 10 tabulator tapes and other related documents were missing entirely, prompting further scrutiny and a referral to the state attorney general for potential sanctions. Investigations also revealed 36 inconsistencies in batch tally sheets, including instances of double-scanned or double-counted ballots, with complaints alleging up to 3,125 duplicated votes. Other irregularities included duplicate scanner serial numbers and missing chain-of-custody forms for some ballots, contributing to ongoing debates and a federal lawsuit by the U.S. Department of Justice to access sealed records for compliance checks.
