Steve Kramer, an American political consultant, said he was behind automated and rigged calls, impersonating the voice of US President Joe Biden. The artificial intelligence (AI)-generated robocall encouraged voters not to vote in New Hampshire's Democratic primaries in January.

Kramer said he hired a magician from New Orleans, Paul Carpenter, to imitate Joe Biden's voice using an AI tool. The consultant indicated that he had received a subpoena from the American telecoms regulator (FCC). He expects to face legal action.
