WASHINGTON (AP) — The Trump administration has revoked the visa of Brazil’s ambassador to the United States in retaliation for Brazil’s denial of visas last month for two American diplomats who sought to visit ahead of upcoming elections as well as Brazil’s stalling on approving President Donald Trump’s nominee to be ambassador in Brasilia. Trump has had a fractious relationship for some time with Lula’s administration, which has opposed him on numerous policies, particularly in the Western Hemisphere regarding Venezuela and Cuba. Lula, who is 80 and seeking his fourth term as Brazil’s president, will face Sen. Flávio Bolsonaro, whose father once served as Brazil’s president and whose family has many ties with the Trump administration. Shortly afterward, the Trump administration classified Brazil’s biggest drug-trafficking groups — First Command Capital and Red Command — as foreign terrorist organizations, a move Lula opposes. The Trump administration also imposed an up to 37.5% tariff hike on thousands of Brazilian exports, which came into force Friday.
