On August 12, 2026, at 11:17 PM — two days before Brazil’s candidate registration deadline — Senator Flávio Bolsonaro’s party affiliation was changed in the TSE (Tribunal Superior Eleitoral) database from PL to Partido Missão. The change blocked his presidential candidacy registration. The TSE confirmed there was no system breach: the affiliation was submitted through Missão’s party system, which internally uses the party Secretary’s credentials to communicate with TSE. What followed was a political firestorm, a police investigation, and mutual accusations between the parties involved.
