U.S. Secretary of State Marco Rubio said on Thursday that the U.S. would respond after former Brazilian President Jair Bolsonaro was convicted of plotting a coup to remain in power after his loss in the 2022 election, although the secretary did not go into detail about what a U.S. response would look like.

“The political persecutions by sanctioned human rights abuser Alexandre de Moraes continue, as he and others on Brazil’s supreme court have unjustly ruled to imprison former President Jair Bolsonaro,” Rubio wrote on X.

“The United States will respond accordingly to this witch hunt,” he continued.

Brazil’s Foreign Ministry argued that Rubio’s comment represented a threat that “attacks Brazilian authority and ignores the facts and the compelling evidence in the records.”

Trump has criticized the Brazilian judicial system and threatened tariffs on the country for its case against Bolsonaro.

In July, the U.S. president placed 50% tariffs on most Brazilian goods in response to a “witch hunt” against Bolsonaro. He later exempted some Brazilian exports, including passenger vehicles and numerous parts and components used in civil aircraft.

Brazilian Supreme Court Justice Alexandre de Moraes, his unspecified allies on the court and his immediate family members will face visa revocations, according to Rubio, who criticized what he called a “political witch hunt” against the former president.

That same month, Rubio announced visa revocations on Brazilian Supreme Court Justice Alexandre de Moraes, who presided over Bolsonaro’s criminal case, and his unspecified allies on the court after the court issued search warrants and restraining orders against Bolsonaro.

The U.S. Treasury Department had also sanctioned the judge over allegations of authorizing arbitrary pre-trial detentions and suppressing freedom of expression.

Bolsonaro’s son, Brazilian Congressman Eduardo Bolsonaro, said he anticipates additional U.S. sanctions against Brazilian justices following his father’s conviction.

“We are going to have a firm response with actions from the U.S. government against this dictatorship that is being installed in Brazil,” he told Reuters on Thursday.

He warned that justices who voted to convict the former president could face sanctions under the Magnitsky Act, which was previously used by the Trump administration against de Moraes.

“If these Supreme Court justices keep following Moraes, they also run the risk of facing the same sanction,” he said.
