Brazilian Supreme Court Justice Alexandre de Moraes, who is overseeing a criminal case against an ally of President Donald Trump, told a court session on Friday that he will continue to do his job and "ignore the sanctions" imposed by the United States that effectively block him from the country's wide-reaching financial system.

Moraes, who oversees the criminal case against ex-president and Trump ally Jair Bolsonaro, is accused of suppressing freedom of expression.

The US imposed sanctions on Brazilian Supreme Court Justice Alexandre de Moraes, escalating its targeting of the judge overseeing legal probes into whether former President Jair Bolsonaro attempted a coup after his 2022 election defeat.
