Trump announced a 50 percent tariff on all Brazilian goods, escalating a feud over Brazil’s prosecution of former president Jair Bolsonaro. Brazil vowed to retaliate.

Tarcísio de Freitas, governor of São Paulo state and a former infrastructure minister under Bolsonaro, told reporters Thursday that the U.S. tariffs would have a negative impact on the economy and for important industrial exporters from his state, including Brazilian plane maker Embraer.

President Donald Trump announced a 50% tariff on goods from Brazil—the highest rate he has announced since he began announcing new levies this week in letters on social media—directly citing the country’s ongoing prosecution of former President Jair Bolsonaro, who he called a “highly respected leader,” as an “international disgrace.”
