The federal Justice Department is defending the legal right to challenge robocalls sent to New Hampshire voters that used artificial intelligence (AI) to mimic President Joe Biden’s voice. Assistant Attorney General Kristen Clarke and U.S. Attorney Jane Young filed a statement of interest in the lawsuit brought by the League of Women Voters against Steve Kramer and the three companies involved in transmitting the calls. The Justice Department argued that robocalls can violate voting rights by incentivizing voters to stay away from the polls, deceive voters with false information, and provoke fear. The message in question falsely suggested that voting in New Hampshire’s presidential primary would prevent voters from casting ballots in November. Kramer, who orchestrated the call, faces criminal charges and a proposed $6m fine. The Federal Communications Commission has also taken steps to combat the use of AI tools in political communications.
