Tennessee Governor Signs AI Disclosure Law Requiring Labels On Political Ads And Deepfakes

Governor Bill Lee signed the Tennessee Artificial Intelligence Transparency Act into law Thursday afternoon during a ceremony at the state capitol in Nashville. The law requires political campaigns, advocacy groups and commercial advertisers to clearly disclose when audio, video or image content has been created or materially altered by artificial intelligence. It takes effect July 1, 2026, roughly four months ahead of the midterm elections.

The legislation passed both chambers with bipartisan support. The House vote was 81 to 14 and the Senate vote was 27 to 4. Democrats and Republicans in the General Assembly worked with the governor's office through February and March on language that would survive a likely First Amendment challenge while still giving voters useful information about what they are watching.

Under the law, any political ad that uses a synthetic voice, a synthetic likeness or an AI generated scene must include a visible on screen label for video content and a clear audio disclaimer for audio content. The disclosure must appear during the entire length of the ad or be read aloud within the first ten seconds. Violations carry civil penalties up to 10,000 dollars per occurrence and can be enforced by the Attorney General or through private right of action by a candidate named or depicted in the content.

Commercial advertising is covered under a separate provision. Companies selling goods or services in Tennessee must label synthetic testimonials, AI generated product demonstrations and altered before and after images. The Department of Commerce and Insurance will handle enforcement on the commercial side and has been given six months to publish guidance for businesses.

Lee said at the signing ceremony that the law was designed to preserve trust in what Tennesseans see and hear in the final stretch of an election year. He pointed to the 2024 New Hampshire primary, when a fake Joe Biden robocall told Democratic voters to stay home, as an example of how quickly the technology can be weaponized. The governor also cited the wave of AI generated celebrity endorsements that began circulating during the 2024 general election.

State Senator Brenda Gilmore, one of the lead Democratic sponsors, said the law is not a ban on the technology and is not intended to slow legitimate use of AI in advertising. She said the goal is disclosure, not prohibition. Senator Jack Johnson, the Republican lead sponsor, framed the measure as a consumer protection issue that should not be controversial. Both sponsors thanked staff from Lee's office for drafting assistance.

Civil liberties groups gave the law a mixed review. The ACLU of Tennessee said in a statement that the bill represents a reasonable approach to a real problem but warned that enforcement will need to be careful not to sweep in satire, parody or clearly labeled commentary. The organization said it will be watching the Attorney General's implementation closely.

Industry response was cautious. The Tennessee Association of Broadcasters said its members support transparency but want clarity about how broadcast stations are expected to verify disclosure compliance on third party ads they run. The association has asked the state for a safe harbor provision that would shield stations from liability if they display ads that advertisers falsely certified as AI free.

Tennessee joins a growing list of states that have passed AI disclosure laws. Michigan, Washington, Minnesota, Texas and California have all enacted similar legislation, though the specific requirements vary. A federal bill from Senators Amy Klobuchar and Josh Hawley has been stuck in committee for more than a year, which has pushed states to move on their own.

For Nashville's growing AI industry, the law adds a compliance item but is not expected to slow development. Local startups working on generative video and voice cloning tools have been preparing watermarking and provenance features in anticipation of regulation. Oracle's Nashville operations, which include an AI research team at the company's River North campus, did not respond to a request for comment Thursday evening.

Black voters and other communities of color have been among the most frequent targets of AI generated disinformation in the 2024 cycle, according to research from the Brennan Center for Justice. The Brennan Center documented dozens of deepfake audio clips that circulated in Black WhatsApp groups and on Spanish language social media during the last election. Advocates in Nashville said they hope the new law gives them a tool to push back when similar content appears locally this year.

Lee said more AI legislation is likely to follow. He has asked the legislature to take up a separate bill next session that would cover AI use in employment screening and tenant screening. For now, campaigns and advertisers in Tennessee have eleven weeks to prepare for the new disclosure rules before they take effect.
