Brazilian Federal Deputy Rui Falcão has petitioned the Supreme Federal Court to investigate alleged foreign interference in the 2026 elections. The request follows evidence suggesting that Argentine national Fernando Andrés Cerimedo used foreign structures to spread disinformation and automate social media accounts.

The petition claims a digital campaign targeting President Luiz Inácio Lula da Silva originated from the Argentine portal La Derecha Diario. This campaign reportedly utilized narratives regarding Moroccan immigrants in Santa Catarina to criticize the administration’s migration policies. Additionally, testimony suggests Cerimedo maintained account automation structures in Bolivia and Buenos Aires, prompting calls for authorities to cross-reference seized equipment from Bolivia with ongoing investigations.
