In one paragraph

Maine requires campaign ads that contain 'synthetic media' of a candidate to carry the disclosure 'THIS COMMUNICATION CONTAINS AUDIO, VIDEO AND/OR IMAGES THAT HAVE BEEN MANIPULATED OR ALTERED.' Synthetic media is an image, audio or video of a candidate that deceptively shows them saying or doing something they did not, or is altered to give a materially different impression; clarity edits, captions, satire and parody are excluded. Violations can bring civil penalties of up to 500% of the expenditure, and the Attorney General can seek injunctions. Broadcasters and newspapers are liable only with actual knowledge. Effective July 29, 2026.

What it means for business

Campaigns, PACs, ad agencies and media buyers running Maine election ads with AI-altered candidate media must add the required disclosure or face penalties up to 500% of the spend.

Key provisions

  1. Public communications that already need a disclosure under 21-A M.R.S. § 1014 must add the manipulated-media statement when they contain synthetic media (§ 1014(5-C))
  2. Synthetic media: a candidate image, audio or video that deceptively depicts things the candidate did not say or do, or gives a materially different impression than the original
  3. Excludes edits for clarity, captions or highlighting that don't change the impression, and satire or parody
  4. Civil penalty up to 500% of the expenditure in violation, with no 10-day cure option (§ 1014(4))
  5. Broadcasters and newspapers violate the rule only if they run a paid communication with actual knowledge it contains synthetic media; a third-party allegation alone is not knowledge
  6. The Ethics Commission sets rules for the disclosure's manner, size and placement; the Attorney General may sue for injunctive relief
  7. Effective July 29, 2026, the general effective date for the session's nonemergency laws
