A bill for an act relating to the use of synthetic media in campaign materials, and making penalties applicable.

Iowa's HSB 643 requires political campaigns and advertisers to clearly disclose when campaign materials (like ads, social media posts, or videos) use digitally manipulated content that falsely mimics a person's appearance or voice. It mandates that such materials prominently display "THIS CONTENT GENERATED USING SYNTHETIC MEDIA," with the publisher solely responsible for compliance. The law applies to all political advertising formats, including online content, print, and broadcast media, directly affecting campaigns and media producers. Violations are classified as a serious misdemeanor, punishable by up to one year in jail and fines up to $2,560.
