The administration of President Donald Trump has cancelled the visa for Brazil’s ambassador in the United States, the latest sign of a deepening diplomatic rift between the two countries. An anonymous US State Department official briefed reporters on Tuesday that Ambassador Maria Luiza Ribeiro Viotti’s visa had been temporarily revoked. The decision to revoke the visa was framed as backlash to Brazil’s decision to withhold approval for Trump’s ambassador to the South American country. The move comes after Washington expressed anger over Brazil’s failure to approve Trump’s choice for ambassador to Brazil, Danny Perez. Brazilian authorities remain wary that the US might seek to influence the outcome of October’s presidential election in favour of Flavio Bolsonaro.
