The Brazilian government has for weeks withheld the formal diplomatic approval needed for the next U.S. ambassador to take up his post, angering U.S. officials and deepening a rift between the Western Hemisphere’s two largest democracies.
The dispute could leave Washington without an ambassador in Brasilia ahead of Brazil’s October election, adding to bilateral tensions that have affected trade flows and resulted in accusations of interference in domestic affairs. Daniel Perez, a Florida state representative and close ally of Secretary of State Marco Rubio, was nominated by U.S. President Donald Trump on June 1. The nomination occurred before the U.S. sought Brazil’s approval, a common diplomatic step known as “agrément,” said four people familiar with the matter.
Officials in Brasilia viewed that omission as a disrespectful breach of protocol, according to two officials who requested anonymity to describe private diplomatic conversations. Mr. Perez’s nomination is awaiting a full Senate vote after passing committee last week, though he will not be able to take up the post until Brazil approves.
In recent days, some Trump officials have grown increasingly exasperated about what they interpret as Brazil’s slow-walking, according to two of the sources. One of the people added, without elaborating, that the administration may take punitive action against Brazil as soon as Friday if the matter is not resolved.
The administration of President Luiz Inacio Lula da Silva, a leftist, has long had a tense relationship with Rubio’s State Department due to what it sees as efforts to influence Latin American politics in favor of conservatives.
The Trump administration, conversely, has accused the Brazilian government of at times censoring conservatives or tilting the scales against them in judicial proceedings.
Asked about Brazil’s delay in granting agrément for Mr. Perez, a State Department spokesperson said:
“President Trump has the right to determine who represents the American people and interests around the world. President Trump is assembling an America First diplomatic A-team across his administration, subject to the advice and consent of the Senate. We reject any effort by foreign countries to interfere in our domestic processes.”
Brazil is investigating Mr. Perez in keeping with standard procedure, two Brazilian officials said. One of them added that agrément will probably not be granted before Brazil’s election on October 4.
“We are not saying we won’t give the agrément, but there is no deadline,” one of the officials said. “It is up to the host country to decide when the appropriate time is.”
Brazil’s Foreign Ministry said in a statement that it would not comment on the matter “as the process is covered by the principle of confidentiality established in the Vienna Convention.”
Perez’s Florida House office did not respond to an email.
Tense relations, fraught election
National sovereignty has become a key rallying cry for Mr. Lula, as he seeks his fourth non-consecutive term in October’s election. His main opponent is Senator Flavio Bolsonaro, the son of former President Jair Bolsonaro, who has sought to portray Mr. Trump as a key ally.
In June, the State Department designated two Brazilian organised crime groups as terrorist organisations, despite opposition from the Brazilian government. Washington imposed a 25% tariff this month on several Brazilian products, citing what it described as unfair trade practices. Last week, it announced an additional 12.5% levy linked to concerns over forced labour. At an event on Wednesday (July 29, 2026), Mr. Lula said Brazil had denied visa requests for two Trump administration officials who, according to him, planned to travel to the country “to meddle in Brazil’s election,” confirming a Reuters report from last week. A U.S. State Department spokesperson at the time rejected any suggestion of a “ploy” to undermine Brazil’s elections.
“Trump sometimes seems to want to pick a fight with me. I don’t want a fight with him … I’m not stupid,” Mr. Lula said on Wednesday (July 29, 2026). “I want to defeat them in the battle of narratives.”
Polls show Mr. Lula with a slim but steady lead over Flavio Bolsonaro. At his committee hearing this month, Mr. Perez told senators that Brazil’s October election would be an early priority if he is confirmed, saying that the U.S. should support conditions for free and fair elections while strengthening trade and security cooperation with Brasilia. “We do have a trade surplus with Brazil,” Mr. Perez said. “Nevertheless, there are some industries that have a significant gap,” referencing energy and agriculture.
