In New York, accounts linked to 'Citizens Against Mamdani' reportedly disseminated AI-generated videos, allegedly featuring fictional constituents criticizing mayor-elect Zohran Mamdani across Instagram, TikTok, and X. Some of these videos were found to display a Sora watermark, and at least one clip was assessed as highly likely to be a deepfake by forensic reviewers. The campaign seemed to simulate grassroots opposition and attracted significant engagement.
