According to a ruling document dated October 27, Brazil's Supreme Court Justice Flávio Dino ordered the federal police to open a case to investigate whether there was foreign financial support and external interference in the country's elections. This investigation will check whether there is an overseas transfer of funds, services, or other benefits related to the election campaign. The police also investigated paid election propaganda content posted by overseas accounts, as well as possible deliberate algorithm manipulation by internet companies. Since members of Congress may be involved, the investigation was overseen by the Supreme Court.
