As AI political deepfakes go viral, lawmakers struggle to keep up – 2 states’ laws show limits of what they can do

As AI political deepfakes go viral, lawmakers struggle to keep up – 2 states’ laws show limits of what they can do
A woman views a manipulated video in January 2019 that changes what is said by President Donald Trump and former President Barack Obama, illustrating how deepfake technology can deceive viewers. Robe LeverAFP via Getty Images Imagine watching a political campaign video in which a candidate admits to taking a bribe. You recognize the face and voice. But the confession is entirely fabricated, thanks to artificial intelligence. Now imagine that your state has passed a law against these AI-generated election deepfakes . Would that mean the video has to be removed from the airwaves? In its June 2026 report, the National Conference of State Legislatures counted 31 states with election deepfake laws . California and Texas enacted their first election-deepfake laws in 2019, but most states adopted theirs in 2024 or later . Among the 31 states, 28 required disclosures. The other three – Maryland, Minnesota and Texas – prohibited certain election deepfakes, even if the content carried an AI warning. In many states, a warning telling viewers the content was generated or manipulated using AI can satisfy a government’s disclosure requirement. The fabricated ad can remain in circulation with that warning. Louisiana, for example, requires AI warnings on certain campaign ads that falsely depict candidates and campaign calls that use artificial versions of public figures’ voices. Maryland, meanwhile, prohibits certain deceptive election deepfakes even when they carry a warning. I am an AI policy scholar at the University of Denver, where we use an AI policy tracker to monitor bills and laws across the U.S. With 2026 midterm elections approaching, the important question for voters is what protection a deepfake law actually provides, and I examine two state laws – in Louisiana and Maryland – to illustrate the limits of what can be done. When a warning is enough Consider a political campaign ad that uses AI to put a candidate’s face onto someone else’s body, making it look as though the candidate said or did something that never happened. A June 2026 Louisiana law requires a clear warning about AI use in ads that meet these conditions. The rule applies to certain messages urging people to vote for or against a candidate, including printed materials, online advertisements and broadcasts. As for videos, adding the required warning can satisfy the disclosure requirement in the Louisiana law. The warning tells voters how the content was made, not whether its accusations are true. It also does not excuse violations of other laws. A 2023 Republican National Committee ad attacking former President Joe Biden illustrates this distinction. It depicted an imagined future after Biden’s reelection, with a warning: “Built entirely with AI imagery.” Although it predates Louisiana’s law, it shows how a disclosure can accompany an ad without stopping its circulation. But this protection does not cover every candidate on the ballot. The Louisiana law excludes candidates for federal office . A fabricated video about a congressional candidate, therefore, does not need an AI warning. For ads involving state and local candidates, leaving out a required warning can have serious consequences. Violators who are found to damage a candidate’s reputation or deceive voters can face a fine of up to US$2,000, up to two years in prison or both. Local district attorneys generally decide whether to prosecute, subject to the state attorney general’s supervision. Louisiana also requires AI disclosures in certain campaign calls, including robocalls. Under a May 2026 law , calls that use AI to reproduce a public figure’s voice must disclose that use at the beginning of the call. The state’s board of ethics enforces the requirement. Violators can face civil fines of up to $2,500 for a first violation and $5,000 for subsequent violations. When a warning will not do Maryland takes a different approach to deceptive election content, prohibiting certain deepfakes even when they carry an AI warning. Maryland’s May 2026 law covers images, audio and video created or altered with AI or other digital tools to falsely depict a person in a way that looks or sounds genuine. Adding a label to that fabricated confession would not, by itself, make it lawful. Whether someone violates the law also depends on their actions and purpose. They must knowingly or recklessly create, use or spread a deepfake to produce materially false information, with an intent such as influencing a voting decision. The law separately requires actual or intended harm to a voter, potential voter or ballot petition, but does not define that harm. Misleading voters about a candidate alone does not automatically establish a violation. A conviction can bring a fine of up to $5,000, up to five years in prison or both. Maryland also gives election officials ways to respond when false voting information is spread. The state’s top election administrator must publicly correct credible reports of misinformation about voting procedures, results or rights. For example, Maryland’s State Board of Elections has a rumor control page to monitor disinformation. The administrator can seek court-ordered removal of misinformation, though not against online services hosting others’ posts. These powers do not let election officials remove every false claim about a candidate. The public can report election misinformation , and officials can pass those reports to the state attorney general. Maryland’s reporting system dates to a 2024 law, but its deepfake prohibition and new removal authority took effect June 1, 2026. Neither guarantees that a correction will reach voters before they cast their ballots. By early September 2026, the Wesleyan Media Project had identified at least 164 political ads nationwide created or enhanced with AI during the 2026 election cycle, accounting for nearly $80 million in ad spending. About 7 in 10 ads carried no AI disclosure, although the count includes uses beyond deceptive impersonations and does not establish how many ads violated a law or misled voters. In this photo illustration created in May 2026, AI-generated images posted on AI influencers’ social media accounts depict a blonde woman lavishing praise on President Donald Trump while criticizing his rivals. Chris Delmas/AFP via Getty Images Does a warning change anyone’s mind? Warnings can make people more skeptical of misleading content. However, whether that affects what they share or how they vote is a separate question. A 2025 study tested warning labels on misleading AI-generated images in two experiments involving 7,579 Americans. People who saw the labels were less likely to believe the posts’ claims. However, warnings that simply identified content as AI-generated did little to change how willing people said they were to engage with it, including sharing it. Warning labels can also raise doubts about accurate information. Another recent study found that people rated headlines as less accurate when they were labeled as AI-generated, regardless of whether the headlines were true or false. Knowing that AI helped produce something does not tell a reader whether its claims are correct. Neither study tested whether a state’s disclosure law changes how people vote. The studies also cannot tell us whether the threat of punishment under Maryland’s law discourages people from creating or spreading deepfakes. Deepfake enforcement Passing a law also does not settle whether officials can enforce it. In September 2026, a federal judge temporarily barred Montana from enforcing its deepfake law , finding that it likely posed a threat to a conservative PAC’s free speech rights under the First Amendment . For voters, gaps in what disclosure laws cover mean that a video without an AI warning has not necessarily passed an authenticity test. The disclosure rule might not cover it, as with congressional candidates under Louisiana’s provision . Moreover, someone may have ignored the law. A warning’s absence cannot tell viewers of the AI content which explanation applies. So, back to that video of a candidate apparently admitting to taking a bribe. It could still reach voters under both Louisiana’s and Maryland’s laws. In Louisiana, a video covered by the disclosure rule can circulate with the required warning. In Maryland, creating or spreading it could lead to punishment if the law’s conditions are not met. Neither approach guarantees that voters will avoid seeing the fabricated confession before casting their ballots. These laws give states ways to respond to deception, but their passage alone cannot guarantee voters that what they are watching is real.

Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Arp 78: Peculiar Galaxy in Aries Explanation: Peculiar spiral galaxy Arp 78 is found within the boundaries of the head strong constellation Aries . Some 100 million light-years beyond the stars and nebulae of our Milky Way galaxy, the island universe is an enormous 200,000 light-years across. Also known as NGC 772 , it sports a prominent, outer spiral arm in this detailed cosmic portrait . Tracking along sweeping dust lanes and lined with young blue star clusters, Arp 78’s overdeveloped spiral arm is pumped-up by galactic-scale gravitational tides. Interactions with its brightest companion galaxy, the more compact NGC 770 seen directly below the larger spiral, are likely responsible. Embedded in faint star streams revealed in the deep telescopic exposure, NGC 770’s fuzzy, elliptical appearance contrasts nicely with spiky foreground Milky Way stars.

Strange giant planet TOI-1355 b set to vanish from view in 2033
Since their first discovery in 1995, hot Jupiter exoplanets (hot Jupiters, for short) quickly challenged our understanding of exoplanet formation and evolution, including exoplanetary system architecture. This is because, as their name implies, they orbit at extremely close distances to their host stars, ranging from a few days to a few hours. Some of their orbits are even oval-shaped, called eccentric in the scientific community, meaning their orbit is oval-shaped. But could such an orbit cause a hot Jupiter to completely vanish from view, preventing astronomers from studying it?

Galaxies in a cosmic house of mirrors
Seeing double… or quadruple! In this Webb image of galaxy cluster MACS J0454.1-0300, we can see the brilliant golden galaxies that make up the cluster and several orange galaxies clustered on one side of the image. The orange galaxies are not part of the galaxy cluster, but rather galaxies much farther away whose light has been bent and magnified by gravitational lensing. This phenomenon occurs when the enormous mass of a foreground object such as a galaxy cluster bends and magnifies the light from a more distant object in the background. In addition to making galaxies look stretched out or bent, gravitational lensing can also make us see double — or quadruple. Under certain conditions, multiple images of the same galaxy can appear. It’s rare to see four or more images of the same galaxy, as this requires the position of the background object and the shape of the massive foreground object to be just so. This happened twice in this image of MACS J0454.1-0300, marking the first time researchers have spotted this more than once in the same galaxy cluster. Read more: esawebb.org/images/potm2609a/ Image Description: A massive galaxy cluster, made of many golden elliptical galaxies with the largest, brightest one in the center. Heavily distorted orange galaxies appear all around the cluster, the largest concentrated in a large arc around the cluster's center; these are images of very distant galaxies, created by gravitational lensing. A few galaxies are large and bluish-white in color; bright, nearby stars are the same color.
