The United States revokes the visa of Brazil’s ambassador in Washington, according to a senior U.S. State Department official cited by multiple outlets. The action follows what the U.S. describes as Brazil withholding formal diplomatic approval for President Donald Trump’s nominee for U.S. ambassador to Brazil, Daniel Perez, and denying visas to two American diplomats. Bloomberg, DW, and others report that the visa was removed as part of a broader diplomatic dispute between the two governments. The outlets identify the Brazilian ambassador as Maria Luiza Ribeiro Viotti. CBS News reports that the U.S. says the visa would be reinstated immediately if Brazil grants the diplomatic approval for Perez. The Jamaica Observer, citing an AFP report, adds that the decision does not mean Brazil’s ambassador is being expelled from the United States. Several reports characterize the move as escalation in tensions between the Trump administration and Brazil’s government. The dispute centers on diplomatic appointments and visa permissions for diplomats involved on both sides.
