Brazil's Advocacia-Geral da União (AGU) will ask U.S. courts to intervene in a lawsuit filed by Rumble and Trump Media against Minister Alexandre de Moraes.
This move signals a significant escalation in the conflict between the Brazilian judiciary and American tech platforms. By intervening, the Brazilian government is elevating a legal dispute between private companies and a judge into a matter of national sovereignty.
The AGU announced the decision on Monday, June 15, 2026 [1]. The agency intends to request authorization from the U.S. justice system to act in the process, arguing that the lawsuit is an attempt to pressure the Brazilian judiciary and offend the country's national sovereignty [2], [3].
According to the AGU, the legal action is a "tentative of offense to national sovereignty and the independence of the Brazilian Judiciary" [4]. The agency's goal is to defend the interests of Brazil within the American legal system, framing the litigation not as a private dispute but as an external attempt at coercion [5].
Supreme Court President Luís Roberto Barroso also weighed in on the matter. Barroso said that the process against the minister in the United States goes beyond a personal issue and constitutes an attempt to cause external embarrassment to the judiciary [6].
The legal battle centers on the actions of Minister Alexandre de Moraes, who has overseen various investigations into disinformation and digital platforms in Brazil. The lawsuit brought by Rumble and Trump Media challenges these judicial actions in a U.S. forum, a move the AGU claims undermines the independence of the Brazilian state [3], [7].
This development occurs as the Brazilian government seeks to maintain its judicial authority over foreign entities operating within its borders. The AGU's intervention aims to ensure that the U.S. courts recognize the legal prerogatives of the Brazilian Supreme Court [2], [5].
“Ação é "tentativa de ofensa à soberania nacional e à independência do Poder Judiciário brasileiro".”
This intervention transforms a corporate legal challenge into a diplomatic and sovereign dispute. By involving the AGU, Brazil is asserting that the judicial actions of Minister Alexandre de Moraes are state acts protected by sovereign immunity, attempting to prevent U.S. courts from ruling on the legitimacy of Brazilian legal procedures.
