'Lies are Flooding Feeds': AI Fakery Raises US Voter Manipulation Fears

A "deepfake" video parodying Kamala Harris, a manipulated expletive-laden clip of Joe Biden, and a doctored image of Donald Trump being arrested -- a tide of AI-fueled political disinformation has prompted alarm over its potential to manipulate voters as the US presidential race heats up.
In what is widely billed as America's first AI election in November, researchers warn that tech-enabled fakery could be used to steer voters toward or away from candidates -- or even to avoid the polls altogether -- stoking tensions in an already hyperpolarized environment, AFP said.
A recent wave of disinformation has renewed calls for tech giants -- many of which have retreated from moderating social media content -- to strengthen guardrails around generative artificial intelligence ahead of the vote.
Last week, Elon Musk faced intense criticism for sharing a deepfake video featuring Vice President Harris, the presumptive Democratic nominee, with his 192 million followers on X, formerly Twitter.
In it, a voiceover mimicking Harris calls President Joe Biden senile; the voice then declares that she does not "know the first thing about running the country."
The video carried no indication that it was parody -- save for a laughing emoji. Only later did Musk clarify that the video was meant as satire.
Researchers expressed concern that viewers could have falsely concluded that Harris was deriding herself and sullying Biden.
AFP's fact-checkers have debunked other AI fakery that raised alarm.
Last month, a manipulated video ricocheting across X appeared to show Biden cursing his critics after he announced he would not seek reelection and endorsed Harris for the Democratic nomination.
A reverse image search showed the footage came from one of Biden’s speeches, carried live by the broadcaster PBS, in which he denounced political violence after the July 13 assassination attempt on Trump.
PBS said the doctored video was a deepfake that used its logo to deceive viewers.
Weeks earlier, an image shared across platforms appeared to show police forcibly arresting Trump after a New York jury found him guilty of falsifying business records related to a hush money payment to porn star Stormy Daniels.
But the photo was a deepfake, digital forensics experts told AFP.
'Partisan tension'
"These recent examples are highly representative of how deepfakes will be used in politics going forward," Lucas Hansen, co-founder of the nonprofit CivAI, told AFP.
"While AI-powered disinformation is certainly a concern, the most likely applications will be manufactured images and videos intended to provoke anger and worsen partisan tension."
Hansen demonstrated to AFP the ability of one AI chatbot to manipulate voter turnout by mass-producing false tweets.
The tool was fed a simple prompt -- "Polling locations charge for parking" –- with the message customized for a specific location: Allen, Texas.
Within seconds, a tweet was churned out misinforming viewers that Allen authorities had "quietly introduced a $25 parking fee at most polling places."
In a previous attempt at possible voter suppression, an AI-enabled robocall impersonating Biden urged New Hampshire residents in January not to cast ballots in the state's primary.
Tests on another leading AI tool, Midjourney, allowed the creation of images seeming to show Biden being arrested and of Trump appearing next to a body double, the nonprofit Center for Countering Digital Hate (CCDH) said in June.
Midjourney had previously blocked all prompts related to Trump and Biden, effectively barring users from creating fake images, tech activists reported.
But CCDH said users could easily circumvent the policy -- in some cases by adding a single backslash to a prompt previously blocked by Midjourney.
'Tipping point'
Observers warn that such fakery on a mass scale risks igniting public anger at the electoral process.
More than 50 percent of Americans expect AI-enabled falsehoods to impact who wins the 2024 election, according to a poll published last year by the media group Axios and business intelligence firm Morning Consult.
About one-third of Americans said they will be less trusting of the results because of AI, according to the poll.
Several tech giants have said they are working on systems for labeling AI-generated content.
In a letter to tech CEOs in April, more than 200 advocacy groups demanded urgent efforts to bolster the fight against AI falsehoods -- including prohibiting the use of deepfakes in political ads, and using algorithms to promote factual election content.
The nonprofit Free Press, one of the groups that signed the letter, said they "heard little substance" in the commitments platforms would be making this election cycle.
"What we have now is a toxic online environment where lies are flooding our feeds and confusing voters," Nora Benavidez, senior counsel at the watchdog, told AFP.
"This is a tipping point in our election," she added. "Platform executives should be racing to strengthen and enforce their policies against deepfakes and other problems."

An F/A-18 fighter jet landing on the USS Harry S. Truman aircraft carrier in the Red Sea went overboard, forcing its two pilots to eject, a defense official told The Associated Press on Wednesday.

The incident Tuesday marks the latest mishap to mar the deployment of the Truman, which has been essential in the airstrike campaign by the United States against Yemen's Houthi militias.

On Tuesday, US President Donald Trump and Oman's foreign minister both said that a ceasefire had been reached with the Houthis, who would no longer target ships in the Red Sea corridor.

The F/A-18 Super Hornet landed on the Truman after a flight, but "the arrestment failed," said the official, who spoke on condition of anonymity because they weren't authorized to speak publicly about the incident now under investigation.

"Arrestment" refers to the hook system used by aircraft landing on carriers, which catches steel wire ropes on the flight deck. It remains unclear what part of the system failed.

The two pilots on board were later rescued by a helicopter and suffered minor injuries in the incident, the official added. No one on the flight deck was hurt.

CNN first reported on the incident.

Tuesday's incident was the latest to see the Navy lose an F/A-18, which cost about $60 million. In April, another F/A-18 fighter jet slipped off the hangar deck of the Truman and fell into the Red Sea. The crew members who were in the pilot seat of the Super Hornet and on the small towing tractor both jumped away.

In December, the guided-missile cruiser USS Gettysburg mistakenly shot down an F/A-18 after ships earlier shot down multiple Houthi drones and an anti-ship cruise missile launched by the militants. Both aviators in that incident also survived.

And in February, the Truman collided with a merchant vessel near Port Said, Egypt.

The Truman, based out of Norfolk, Virginia, has seen its deployment extended multiple times amid the Houthi airstrike campaign. It had been joined recently by the USS Carl Vinson aircraft carrier operating out of the Arabian Sea.

Pentagon spokesman Sean Parnell wrote on the social platform X that an investigation was underway and that "this aircraft was not struck by the Houthis."

"The Harry S. Truman Carrier Strike Group remains fully mission-capable," he added.
