"The flagrant conduct of obstruction of Brazilian justice, incitement of crime, the public threat of disobedience of court orders and future lack of cooperation from the platform are facts that disrespect the sovereignty of Brazil," wrote de Moraes - who Musk called "Brazil's Darth Vader" over the weekend.

While X initially said in a Saturday post that they would comply, blocking certain popular accounts in Brazil - Musk said an hour later, after the release of the "TWITTER FILES BRAZIL," that they would not, noting that "As a result, we will probably lose all revenue in Brazil and have to shut down our office there."

in a Sunday post, Musk said that Supreme Court Justice Alexandre de Moraes had "brazenly and repeatedly betrayed the constitution and people of Brazil," and should "resign or be impeached."

De Moraes said that as part of his decision to open an inquiry, that "X shall refrain from disobeying any court order already issued, including performing any profile reactivation that has been blocked by this Supreme Court," Reuters reports.

The justice said that Musk would face a fine that equates to approximately $20,000 each time an account is reactivated on X.
