Trump's Escalating Diplomatic Feud: What's at Stake for Brazil and Beyond The revocation of Brazil's ambassador to the US, Maria Luiza Ribeiro Viotti, marks a significant escalation in the already fraught diplomatic relations between Washington and Brasília.
The move is widely seen as a retaliatory measure aimed squarely at President Luiz Inácio Lula da Silva, who has been vocal about his opposition to US interventionism in Latin American politics.
The decision to revoke the ambassador's visa comes on the heels of Brazil's refusal to approve Trump's nominee for ambassador, Daniel Perez.
