California is racing to combat deepfakes ahead of the election

Days after Vice President Kamala Harris launched her presidential bid, a video -- created with the help of artificial intelligence -- went viral. "I ... am your Democrat candidate for president because Joe Biden finally exposed his senility at the debate," a voice that sounded like Harris' said in the fake audio track used to alter one of her campaign ads. "I was selected because I am the ultimate diversity hire." Billionaire Elon Musk -- who has endorsed Harris' Republican opponent, former President Trump-- shared the video on X, then clarified two days later that it was actually meant as a parody. His initial tweet had 136 million views.
