Brazil’s president, Luiz Inacio Lula da Silva, had just returned to his office from a meeting with Indonesia’s prime minister when the reports began blaring on TV.

Brazilian President Luiz Inácio Lula da Silva said Thursday that his government has not been successful in trying to negotiate the 50% tariff on Brazilian imports that U.S. President Donald Trump has threatened to impose.

Brazil’s President forcefully rebuked Trump after the U.S. leader called the prosecution of Lula’s predecessor, Bolsonaro, a “witch hunt” and hiked tariffs on the Latin American nation.
