Brazilian deputy sues TSE over unregistered WhatsApp channel by rival lawmaker

Federal Deputy Erika Hilton filed a court action with Brazil's Superior Electoral Court (TSE) seeking suspension of the 'Tropa do Flávio' WhatsApp channel managed by Deputy Nikolas Ferreira, citing lack of electoral registration. The move escalates a political dispute ahead of the 2026 elections, raising questions about campaign finance and digital platform regulation. The TSE's ruling could set precedent for social media political groups.
