Donald Trump has vowed to impose tariffs on Brazil and sanction the judge trying former president Jair Bolsonaro over an alleged coup attempt. The US President has vowed to slap the South American nation with 50 per cent tariffs from Friday unless they call off what he called the "witch hunt" of Bolsonaro.

The US has sanctioned Brazilian Supreme Court Justice Alexandre de Moraes, who is overseeing a trial of President Donald Trump's right-wing ally Jair Bolsonaro.

U.S. Treasury Department sanctioned the Brazilian judge overseeing case against former President Jair Bolsonaro days after the State Department revoked visa.
