U.S. Revokes Brazilian Ambassador's Visa, Escalating a Year-Long Visa Campaign Targeting Brazilian Officials

The U.S. revoked the visa of Brazil's ambassador, Maria Luiza Ribeiro Viotti, on August 4, 2026, retaliating for Brazil's denial of visas to U.S. diplomats. Viotti was not expelled. The move extends a campaign that began in July 2025 with visa revocations for Supreme Federal Court Justice Alexandre de Moraes and allies — widening from Brazil's judiciary to its top diplomat in Washington.
