The State Department has revoked the visa of Brazil's ambassador to the United States, Maria Luiza Ribeiro Viotti, in a move that marks a sharp escalation in diplomatic friction between the two governments. The action, taken Tuesday, was described by a State Department spokesperson as a "reciprocal action" in response to Brazil's failure to approve President Trump's nominee to serve as the U.S. ambassador in Brasília.
According to the spokesperson, the Brazilian government has yet to grant its formal approval—known as "agrément"—to Daniel Perez, the speaker of the Florida House, whom President Trump nominated in early June. The spokesperson defended the move, saying, "President Trump has the right to determine who represents the American people and interests around the world." The official also added that the department rejects "any effort by foreign countries to interfere in our domestic processes."
The Brazilian government, however, pushed back against that justification. In a statement from the office of President Luiz Inácio Lula da Silva, officials "repudiated" the revocation and argued that the Trump administration had "publicly announced the name of its nominee before formally requesting agrément from the Brazilian Government." The statement emphasized that "Brazil strictly adheres to international law. The Vienna Convention establishes no deadline for the granting of agrément. The U.S. request remains under consideration."
Viotti, who has served as Lula's ambassador to the U.S. since June 2023, now faces an uncertain status. The revocation is the latest in a series of hostile exchanges that have strained a relationship that has historically been marked by cooperation.
The Brazilian government also accused two U.S. officials of attempting to enter Brazil recently "in order to cast doubt" on the country's electoral system, a charge that Washington has not directly addressed. This comes amid broader accusations from Trump and his administration that Lula's government has targeted former Brazilian President Jair Bolsonaro. Bolsonaro is barred from running for office this year due to a Supreme Court ruling, but his son, Flávio Bolsonaro, is challenging Lula for the presidency.
Lula's office framed Tuesday's visa revocation as part of a broader pattern, stating: "Today's decision is not an isolated incident. It is part of a deliberate escalation of hostile measures against Brazil, motivated by ideological considerations that are incompatible with a bilateral partnership that has always been grounded in mutual respect."
The diplomatic row adds to growing economic tensions. Last month, the office of U.S. Trade Representative Jamieson Greer imposed 25 percent tariffs on certain Brazilian imports, citing Brazil's digital trade policies, weak anti-corruption enforcement, and its own tariffs. That action, taken under Section 301 of the Trade Act of 1974, has further complicated the relationship.
The situation has drawn attention from political observers, especially as the Trump administration's trade policies have sparked legal challenges from several states. In a related development, a coalition of two dozen Democratic-led states has filed suit over the administration's latest tariff push, as reported in a recent article on the lawsuit over tariffs. The ongoing friction with Brazil underscores the administration's willingness to use leverage in diplomatic and trade matters, even with traditional partners.
As the standoff continues, the question of when—or if—Brazil will grant agrément to Daniel Perez remains open. Meanwhile, the revocation of Ambassador Viotti's visa signals that Washington is prepared to retaliate when it perceives delays or disrespect. The coming weeks may reveal whether both sides can de-escalate, or whether this marks a lasting downturn in U.S.-Brazil relations.
