Brazil's Supreme Court has ordered that the former right-wing President Jair Bolsonaro be put under house arrest.
He is standing trial over allegations he plotted a coup, which he denies.
President Donald Trump has used Mr Bolsonaro's trial, which he calls a "witch-hunt", as a justification for imposing 50% tariffs on some Brazilian goods despite the US having a trade surplus with Brazil.
The judge in charge of investigating Mr Bolsonaro, Alexandre de Moraes, said the decision was because Mr Bolsonaro hadn't complied with restraining orders put on him last month.
Mr Moraes, who the US has also sanctioned, said Mr Bolsonaro had used the social networks of his allies including his sons to spread messages that encouraged attacks on the Supreme Court and foreign intervention in the Brazilian judiciary.
