Justice Alexandre de Moraes has presided over the criminal case against Bolsonaro, who has been charged with plotting a coup to overturn Brazil’s 2022 presidential election.

Also on Wednesday, U.S. President Donald Trump signed an executive order imposing a 50% tariff on Brazilian goods, which he has said was meant to stop the “witch hunt” against his right-wing ally Bolsonaro.

Moraes was sanctioned under the Global Magnitsky Act, which allows the U.S. to impose economic penalties against foreigners it considers to have a record of corruption or human rights abuses. Secretary of State Marco Rubio told lawmakers in June that Washington was considering sanctions against the judge.

“Alexandre de Moraes has taken it upon himself to be judge and jury in an unlawful witch hunt against U.S. and Brazilian citizens and companies,” U.S. Treasury Secretary Scott Bessent said in a statement.

Moraes, he said, “is responsible for an oppressive campaign of censorship, arbitrary detentions that violate human rights, and politicized prosecutions — including against former President Jair Bolsonaro.”

The sanctions call for freezing all U.S. assets held by Moraes and prohibit U.S. citizens from doing business with him.

There was no immediate comment from Moraes or Brazil’s Supreme Court.
