The robocalls came from a nonexistent group called the "1599 project" and falsely warned recipients that voting by mail would result in being "finessed into giving your private information to the man."
Michigan Attorney General Dana Nessel said in a press release that the calls were made in August to almost 12,000 residents with phone numbers from the 313 area code that covers Detroit. An investigation found that attorneys general in New York, Pennsylvania, Ohio and Illinois received complaints about similar phone calls being placed to cities with large minority populations.
In the calls, the robocaller told recipients to "beware of vote by mail" and falsely said that doing so would feed personal information into a database accessible to the police pursuing warrants, credit card companies collecting debts and the Centers for Disease Control and Prevention aiming to track people for mandatory vaccines.
