What Happened Between Brazil and the US?

The United States State Department revoked the visa of Brazil's ambassador to Washington, Maria Luiza Ribeiro Viotti, on Tuesday, August 4. The move triggered a sharp reaction from the Brazilian government, which called the action part of a deliberate pattern of hostility rather than an isolated incident.

Why Did the US Revoke the Visa?

According to a senior State Department official, the revocation came in response to two Brazilian actions: Brazil's decision to withhold approval of the agrément for Trump's nominated ambassador to Brasília, Daniel Perez, and Brazil's refusal to grant visas to two American government officials.

What Is Brazil's Response?

Brazil's Presidential Communications Secretariat (Secom) issued a strongly worded statement rejecting both justifications, calling them "false." The Palácio do Planalto said the two American officials whose visas were denied had planned to travel to Brazil to cast doubt on the integrity of the Brazilian electoral system — an "unacceptable attempt to interfere in the national political process." The Foreign Ministry had already denied those visas after concluding the mission aimed to question Brazil's electoral system.

What Broader Tensions Exist?

Secom's statement also noted that Washington's individual sanctions against Brazilian authorities remain in force, including visa revocations based on what Brazil called an "unfounded allegation of political persecution" of former president Jair Bolsonaro. Health Minister Alexandre Padilha and his family members are among those affected. Brazil also accused the US of seeking to interfere in the upcoming presidential election.

Who Is Daniel Perez?

Daniel Perez is a Republican politician who serves as Speaker of the Florida House of Representatives and is a Trump ally. The son of Cuban immigrants, his nomination fits into a broader US focus on Latin America in its foreign policy. His nomination was announced publicly before Brazil was consulted — skipping the traditional diplomatic courtesy of prior consultation — which caused discomfort in Brasília. The ambassador post has been vacant since early 2025.
