As the U.S. election unfolds, several viral claims of voting fraud have raised concerns online. BBC Verify addresses four prominent accusations, including allegations of pre-marked ballots in Kentucky and military absentee ballot issues. Election officials have refuted these claims, emphasizing that mail-in ballots are valid even with multiple markings, and clarifying that the Pentagon does not handle absentee ballot distribution. Additionally, accusations of ‘illegal voters’ in Pennsylvania and faulty voting machines have also been investigated, with officials affirming the rarity of voter fraud and the integrity of election processes.
