Analysis & Obligations
§ 130.031(11)
Generative AI disclosure for political advertisements
Publisher

(11) 1 Any person publishing, circulating, or distributing any political advertisement relative to any candidate for public office or any ballot measure that uses generative artificial intelligencegenerative artificial intelligence"generative artificial intelligence" means an advertisement that contains images, video, audio, text, or other digital content created in whole or in part by a machine-based system that can, for a given set of human-defined objectives, emulate the structures, patterns, and characteristics of input data in order to generate synthetic content.§ 130.031(11) shall, on the face of such advertisement, identify in a clear and conspicuous manner that generative artificial intelligencegenerative artificial intelligence"generative artificial intelligence" means an advertisement that contains images, video, audio, text, or other digital content created in whole or in part by a machine-based system that can, for a given set of human-defined objectives, emulate the structures, patterns, and characteristics of input data in order to generate synthetic content.§ 130.031(11) was used in the creation of the advertisement. As used in this subsection, the term "generative artificial intelligencegenerative artificial intelligence"generative artificial intelligence" means an advertisement that contains images, video, audio, text, or other digital content created in whole or in part by a machine-based system that can, for a given set of human-defined objectives, emulate the structures, patterns, and characteristics of input data in order to generate synthetic content.§ 130.031(11)" means an advertisement that contains images, video, audio, text, or other digital content created in whole or in part by a machine-based system that can, for a given set of human-defined objectives, emulate the structures, patterns, and characteristics of input data in order to generate synthetic content.

New subsection 11 imposes a disclosure obligation on any person who publishes, circulates, or distributes a political advertisement that uses generative artificial intelligence. The advertisement must identify, in a clear and conspicuous manner on its face, that generative AI was used in its creation. The subsection also defines the term generative artificial intelligence for purposes of this requirement.

The obligation tracks the structure of the existing subsection 8 "Paid for by" disclosure for printed political matter, extending the disclosure paradigm to AI-generated content. Notably, the bill does not specify the exact label language beyond requiring identification that generative AI was used, and it applies to any person involved in publishing, circulating, or distributing the advertisement — not just the person who paid for it or the person who used the AI tool.

CP-01.6
§ 130.031(12)
Violation for refusal or false identification of sponsor

(12) It shall be a violation of this chapter for any person required to be identified as paying for printed matter pursuant to subsection 8 of this section or paying for broadcast matter pursuant to subsection 9 of this section to refuse to provide the information required or to purposely provide false, misleading, or incomplete information.

Subsection 12 (renumbered from the prior subsection 12 — no substantive change to this provision) makes it a violation of the chapter for any person required to identify themselves as paying for printed or broadcast matter under subsections 8 or 9 to refuse to provide the required information or to purposely provide false, misleading, or incomplete information. This is an existing enforcement provision that was not substantively amended by the bill.

§ 130.031(13)
Prohibition on prize incentives for election material distribution

(13) It shall be a violation of this chapter for any committee to offer chances to win prizes or money to persons to encourage such persons to endorse, send election material by mail, deliver election material in person or contact persons at their homes; except that, the provisions of this subsection shall not be construed to prohibit hiring and paying a campaign staff.

Subsection 13 (renumbered from former subsection 12) prohibits committees from offering chances to win prizes or money to encourage persons to endorse, mail, deliver, or promote election material. This is an existing provision that was not substantively amended — it was merely renumbered to accommodate the new subsection 11.
