Requires political ads produced using AI to have a disclosure and creates a penalty for failure to disclose the use of AI
HB673 repeals and reenacts Missouri’s campaign finance and political advertising disclosure section, section 130.031, while keeping many existing rules intact and adding a new disclosure requirement for political advertisements created with generative artificial intelligence. The bill continues to regulate contribution limits, petty cash use, anonymous contributions, out-of-state committee contributions, and sponsor identification for printed and broadcast political materials. It also preserves existing prohibitions on concealing the true source or recipient of campaign money and on using prizes or money to induce political activity.
The new substantive change is that any person publishing, circulating, or distributing a political advertisement relating to a candidate or ballot measure that uses generative AI must clearly and conspicuously disclose that AI was used in creating the ad. The bill defines generative artificial intelligence broadly to include machine-based systems that generate synthetic images, video, audio, text, or other digital content. It also makes it a violation to refuse required sponsor-identification information or to provide false, misleading, or incomplete information, reinforcing enforcement of disclosure rules.
HB673 would amend Missouri campaign finance law by adding an explicit disclosure obligation for AI-generated political advertising and by updating the state’s political advertisement identification rules. It affects candidates, committees, political parties, donors, printers, broadcasters, and any person distributing political ads, while leaving the core contribution and reporting framework in place. The bill would also continue to govern anonymous donations, petty cash limits, and sponsor attribution requirements for printed and broadcast election materials, with penalties tied to violations of the chapter.
The available context suggests generally favorable or at least noncontroversial treatment of the bill, with the stated purpose focused on transparency in political advertising and modernizing disclosure rules for AI-generated content. No committee transcript or recorded vote information is provided, so there is no evidence of organized opposition or debate in the supplied materials. The bill caption itself frames the measure as a disclosure and penalty bill, indicating a compliance-oriented approach rather than a broader policy shift.
The main potential point of contention is the new requirement to label political ads that use generative artificial intelligence, which could raise questions about how broadly the term is interpreted, how burdensome the disclosure will be for campaigns and vendors, and how enforcement would work for mixed-content ads. Another possible issue is the bill’s continued regulation of anonymous contributions and sponsor-identification rules, though those provisions appear to be carried forward from existing law rather than newly controversial changes. No specific opposing arguments are documented in the provided materials.
