Donald Trump’s administration has revoked the visa of Brazil’s ambassador to the US in a sharp escalation of a diplomatic feud with the country’s president, Luiz Inácio Lula da Silva.
The US state department said Maria Luiza Ribeiro Viotti’s visa had been cancelled in retaliation for Brazil’s refusal to approve Trump’s nominee for ambassador in Brasília and its decision last month to deny visas to two US diplomats seeking to visit ahead of an October election.
