What happened

An AI-generated deepfake video falsely accusing Argentine radio journalist Julia Mengolini of incest circulated widely online, depicting her in explicit sexual content with her brother.

President Javier Milei posted at least 65 messages on X directed at Mengolini during the weekend, mocking the victim while his followers continued to share and ridicule the false video.

Reported impact

Experts stated that Milei's rhetoric, often filled with misogynistic insults and sexual innuendo, is undermining press freedom and increasing the risk of real-world violence against journalists.

This incident represented one of the most extreme episodes in an escalating campaign of attacks against journalists by the president and his allies.

Index analysis

The deepfake video demonstrated the deployment of AI-generated synthetic media as a tool for targeted harassment and defamation against a journalist who had been critical of the government.
