“Swifties for Trump is a massive movement that grows bigger every single day,” Trump campaign spokesperson Steven Cheung said in a statement when asked for comment about the fake Swift image.
Several Swift fans and watchdog groups said many of the images posted by Trump appeared to be deepfakes generated by artificial intelligence.
Advocates in the music industry, Hollywood and Washington have been pushing for federal legislation and other measures to fight the explosion of fake AI images online.
Trump’s post was “yet another example of AI’s power to create misinformation”, consumer group Public Citizen said.
“The potential harms to our society that could result from such misinformation, including abuses of our elections, are wide-reaching and immensely damaging,” the group added.
