In one paragraph
Montana bars people and groups working in an official election capacity from paying for or sponsoring an election or electioneering communication they know, or should know, is a deepfake of a candidate or party on the ballot, within 60 days before voting begins, unless it carries the disclosure 'This (image/audio/video/multimedia) has been significantly edited by artificial intelligence and depicts speech or conduct that falsely appears to be authentic or truthful.' Aggrieved candidates can sue; repeat violations become crimes. News coverage, satire, paid broadcasters and online platforms are exempt. Effective October 1, 2025.
