The creator of a viral July post on X that used artificial intelligence to mock Vice President Kamala Harris’s campaign is suing to block a California law regulating political AI and deepfakes. Gov. Gavin Newsom (D-CA) signed AB 2839 into law in an attempt to keep AI-aided political disinformation out of the election.

In July, the X user shared a digitally altered campaign video mocking Harris, which Elon Musk then boosted and shared.

California Gov. Gavin Newsom signed legislation Tuesday banning “deepfakes" but X owner Elon Musk quickly reshared an unflattering AI-doctored video of Vice President Kamala Harris.
