The lawsuit came hours after the justice received an indictment of Brazil’s former president, who is an ally of President Trump.
President Trump’s media company sued a Brazilian Supreme Court justice on Wednesday, accusing him of illegally censoring right-wing voices on social media.
The unusual move was made all the more extraordinary by its timing: Just hours earlier, the Brazilian justice had received an indictment that would force him to decide whether to order the arrest of Jair Bolsonaro, the former Brazilian president and an ally of Mr. Trump. The justice is overseeing multiple criminal investigations into Mr. Bolsonaro.
The Trump Media & Technology Group — which is majority owned by Mr. Trump and runs his Truth Social site — sued the Brazilian justice, Alexandre de Moraes, in U.S. federal court in Tampa, Fla., on Wednesday morning. Joining as a plaintiff was Rumble, a Florida-based video platform that, like Truth Social, pitches itself as a home for free speech.
The lawsuit appeared to represent an astonishing effort by Mr. Trump to pressure a foreign judge as he weighed the fate of a fellow right-wing leader who, like him, was indicted on charges that he tried to overturn his election loss.
Mr. Bolsonaro had explicitly called on Mr. Trump to take action against Justice Moraes in an interview with The New York Times last month. At the time, it was not clear how Mr. Trump might be able to influence Brazil’s domestic politics.
Mr. Bolsonaro was indicted on charges Tuesday that he plotted to hold on to power after he lost Brazil’s 2022 election, including by participating in plans to assassinate Justice Moraes. The indictment said that Mr. Bolsonaro effectively approved the plot and that military agents had begun tracking the movements of the judge.
