“Ballot harvesting” refers to the collection of completed absentee or mail-in ballots by a person or group who return the ballots on behalf of the voters. It is a controversial practice that some say helps to enfranchise vulnerable voters while others say it opens the door to voter fraud. A 2022 film claimed that ballot “mules” harvested 400,000 illegal votes to the benefit of Joe Biden, but independent fact checkers disagreed.
