The United States has canceled the visa of Brazil’s ambassador, the sharpest move yet in a feud between Washington and Brasilia that comes down to one thing: Brazil’s election in October.
The State Department revoked the diplomatic visa of Maria Luiza Ribeiro Viotti, Brazil’s ambassador in Washington, on Tuesday. The move has precise limits. Viotti has not been expelled. No one has branded her persona non grata. She can remain in the country, but leaving would mean going through the visa process again to get back in. The move is reversible, and American officials say it could be undone quickly if Brazil does what Washington asks.
What Washington asks is approval of its own ambassador. President Trump nominated Danny Perez, a former Florida House speaker, to be ambassador in Brasilia on June 1. Brazil has not approved him. American officials say Brasilia has signaled it will not act until the first ballot, set for October 4, is over, and the ambassador’s post has stood empty since Trump returned to office in January 2025.
The visa revocation is also payback. Last month Brazil refused entry to two American officials: Riley Barnes, who runs the State Department’s bureau on democracy, human rights and labor, plus one of his senior aides. Both were booked to visit Brasilia in late July. Washington said the agenda covered trust in the ballot, religious freedom and free speech. Brasilia said the pair had planned to sow doubt about the integrity of its electoral system, an unacceptable interference, and the State Department called that charge baseless.
American officials say the revocation was delayed several times to let Lula climb down. He did not. Brazil’s government answered with a statement accusing Washington of breaching international law by naming Perez before seeking consent in private, as the Vienna Convention requires, and calling the visa decision political, aimed at the October vote.
Both accusations of election meddling are now on the table, from both directions, and the context makes them hard to wave away as protocol.
Lula, eighty years old and seeking a fourth term, faces Flavio Bolsonaro, son of the ex-president Jair Bolsonaro, who was convicted of an attempted coup and now serves a 27-year sentence under house arrest. The Trump administration’s sympathies in that contest are well known. Bolsonaro’s sons visited Washington in late May and met with Trump. Weeks later, Washington classified two of Brazil’s biggest drug-trafficking groups as foreign terrorist organizations, over Lula’s objections, and imposed tariffs of up to 37.5 percent on Brazilian exports, citing unfair trade practices and forced labor. Brasilia read each move as pressure timed to the campaign.
Lula has kept his fire off Trump personally, saying the two got along when they met at the United Nations last September, and has pointed at Rubio instead. Brasilia called the revocation part of a deliberate campaign of hostile measures, ideological in motive. A Brazilian diplomat put the underlying question plainly: why is Washington in a hurry to place its ambassador just months before the vote? Brazil’s government insists it has tried everything to repair the relationship.
The result is a diplomatic standoff in which small moves carry the weight: a visa canceled, a nomination frozen, a charge of interference answered by a counter-charge. The ambassador keeps her post in all but paperwork, and the visa will come back if Perez is approved, but approval is being held hostage to an election that neither capital trusts the other to keep its hands off. The election is where both sides are playing.
