What PT Lawmakers Are Alleging About Milei and the AI Bolsonaro

Federal deputies from Brazil’s Workers’ Party (PT), the party of President Luiz Inácio Lula da Silva, have filed petitions with the Prosecutor-General’s Office (PGR) alleging that the Liberal Party (PL) convention on July 25, 2026, involved two clear breaches of electoral law. The event officially nominated Senator Flávio Bolsonaro as the party’s presidential candidate.

The first complaint targets Argentine President Javier Milei, who appeared on stage with Flávio and delivered a speech that the lawmakers say went far beyond diplomatic courtesy. Milei openly endorsed the candidate, asked Brazilians to vote for him, insulted Lula and Supreme Court Justice Alexandre de Moraes, and attacked the court’s decision that led to Jair Bolsonaro’s imprisonment. The PT deputies argue this constitutes illegal foreign participation in a party event and electoral propaganda.

The second complaint concerns an artificial intelligence-generated video shown at the convention that simulated Jair Bolsonaro—who is under house arrest serving a 27-year, 3-month sentence for attempted coup—declaring Flávio as his chosen successor. The PT representatives assert that the use of AI to create a lifelike endorsement from a person without political rights violates the same electoral code that prohibits participation by ineligible individuals, and amounts to a serious risk of misleading voters.

The Legal and Political Fallout from the PL Convention

The Milei Precedent: Where Foreign Endorsement Crosses the Line

The petitioners cite a specific article of Brazil’s electoral code that bans foreign participation in party activities, rallies, and propaganda. Milei’s speech appears to fit that description: he explicitly named the election date, attacked the opposing candidate, and urged voters to back Flávio. What is less clear is how the PGR will weigh the fact that Milei is a sitting head of state—potentially turning a legal complaint into a diplomatic crisis. Brazil’s Foreign Ministry had already recalled its ambassador from Buenos Aires for consultations after the speech, and this petition could further strain relations.

AI Deepfake and the Law: A Gray Area with Immediate Consequences

The AI video of Jair Bolsonaro represents a newer legal frontier. Deputy Dandara (PT-MG) argued that it “represents a grave affront to electoral legislation, with the potential to unbalance the race and induce the electorate to error.” While Brazil’s electoral rules have recently been updated to address some forms of digital manipulation, the specific application to a deepfake of a disqualified candidate has not been tested at this level. The demand for immediate suspension of the video could force the courts to set a swift precedent on whether AI-generated content from a politically barred figure counts as an illegal act in itself.

Political Calculus: PT’s Early Legal Offensive

The petitions are a clear attempt to hobble Flávio Bolsonaro’s campaign at its start. By raising both the foreign interference and AI misuse narratives, the PT aims to frame his candidacy as reliant on disqualified and external actors. Even if no immediate legal sanctions are imposed, the investigation itself can draw weeks of negative attention and force the campaign to spend resources on legal defense. The PGR has the authority to request provisional measures from the Superior Electoral Court, including ordering the video’s removal, which would be a tangible early blow.

What the Petition Means for the 2026 Election and Key Players

  • Flávio Bolsonaro’s campaign should brace for possible court-ordered removal of the AI video, given that Deputy Dandara’s petition explicitly requests immediate suspension. A takedown would deprive the campaign of a powerful emotional tool at a crucial early stage.
  • The Lula government and PT are likely to amplify the Milei angle, portraying Flávio as a candidate backed by a foreign leader who insulted Brazil’s president and Supreme Court. This narrative could resonate with moderate voters wary of foreign meddling.
  • Brazil’s diplomatic posture toward Argentina may harden further if the PGR formally deems Milei’s speech an illegal electoral intervention. Even symbolic measures could chill the bilateral agenda, affecting trade and political coordination in Mercosur.
  • The electorate should watch for a PGR response that clarifies how AI-generated content will be treated under election law—a ruling that will set boundaries for all campaigns through the rest of the 2026 cycle.
