What happened

Profiles on TikTok are using AI-generated video content to spread political disinformation in Brazil. The profiles typically feature a rightward bias and focus on figures including US President Donald Trump, Brazilian President Lula, Chinese President Xi Jinping, former Brazilian President Jair Bolsonaro, and Brazilian Supreme Court (STF) ministers such as Alexandre de Moraes.

When searching for Moraes on TikTok, the third result displayed content claiming Trump would invade Brazil to arrest Moraes, a claim debunked by fact-checker Comprova. Of five recent videos from one such profile reviewed up to September 1, four contained disinformation that mixed true information with false claims.

Reported impact

The proliferation of AI-generated political content on the platform has drawn attention from TikTok users, who report uncertainty about whether such videos constitute disinformation.
