HB 673 Missouri House · 2025 Regular Session

Requires political ads produced using AI to have a disclosure and creates a penalty for failure to disclose the use of AI

HB 673's title claims it addresses AI in political ads, but the provided bill text contains no provisions about artificial intelligence. Instead, the text outlines campaign finance disclosure rules, requiring printed materials (including advertisements) to identify the sponsor with "Paid for by" statements and imposing limits on anonymous contributions (e.g., $25 maximum anonymous contribution). It also details record-keeping requirements for committee expenditures and fund-raising events. The bill's actual focus is on traditional campaign finance transparency, not AI disclosure, so the title does not match the content.
