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 October elections. The U.S. is also impatient with what it sees as Brazil’s stalling on approving President Donald Trump’s nominee to be ambassador in Brasilia. State Department officials said the step had been delayed several times to give Brazilian President Luiz Inácio Lula da Silva room to back down, something he did not do. They said, however, that it could be quickly reversed if Brazil accepts Trump’s ambassadorial choice. Brazil's government responded by saying the U.S. decision was politically driven with the aim of influencing Brazil’s election.
