US revokes visa for Brazilian ambassador

The US State Department has revoked the visa of Brazil's ambassador, Maria Luiza Ribeiro Viotti, escalating a diplomatic feud with President Luiz Inácio Lula da Silva. This retaliatory action follows Brazil's refusal to approve Donald Trump's nominee for ambassador in Brasília. Additionally, the US move responds to Brazil's recent decision to deny visas to two US diplomats planning a visit before the October elections, further deepening the diplomatic rift between the two South American and North American nations.
