The Brazilian government has blocked a U.S. delegation from traveling to the country next week, concerned that the visitors would seek to cast doubt on the safety of the nation’s electoral systems ahead of a presidential contest this year, according to U.S. and Brazilian officials.
The U.S. delegation included two senior State Department officials, Riley M. Barnes and Samuel Samson, according to three senior U.S. and Brazilian government officials, who spoke anonymously to discuss confidential diplomatic matters. On Friday, Brazilian authorities rejected their requests for a visa, according to two of those officials, derailing the planned visit.
The State Department did not immediately respond to a request for comment. A spokesman for Brazil’s foreign ministry confirmed the visa rejections, but did not provide a reason.
In the visa application, submitted on Monday, the U.S. officials said they planned to meet with electoral authorities to discuss Brazil’s voting systems and concerns about possible restrictions to the freedom of expression in the lead-up to the Oct. 4 elections, according to one of the Brazilian officials.
The decision to bar the U.S. delegation is the latest escalation between the nations after several weeks of heightened tensions following new tariffs and ideological clashes on issues like organized crime.
It also fuels concerns among many Brazilians over possibly more meddling by President Trump in Brazil’s internal affairs, this time aiming for a voting system that global observers widely regard as secure. At the same time, the move to bar the delegation risks stoking complaints from conservatives in both countries about a lack of transparency ahead of the high-stakes election.
In a region where the right is fast ascending, Brazil’s electoral contest, which will pit a leftist incumbent against a right-wing challenger, will serve as the left’s biggest test this year.
Mr. Barnes and Mr. Samson also planned to meet with Flávio Bolsonaro, the son of former President Jair Bolsonaro, who is serving a 27-year sentence for plotting a coup, according to the officials. The younger Mr. Bolsonaro is challenging the leftist incumbent, Luiz Inácio Lula da Silva, for the presidency. He has made multiple trips to Washington in recent months, some of them to seek support for his political agenda.
Experts widely regard the South American nation’s voting systems, which use biometrics to identify voters and tallies results almost immediately after polls close, as some of the most secure in the world. The country’s elections are regularly monitored by dozens of independent observers from around the world.
After Mr. Bolsonaro’s statements this week, Brazilian authorities became convinced that the U.S. delegation was not on a fact-finding mission, but rather planned to undermine confidence in the country’s voting systems, according to the two Brazilian officials.
Mr. Barnes, an assistant secretary, and Mr. Samson, a deputy assistant secretary, do not have expertise or significant experience in Brazil, according to one U.S. official. Mr. Samson has played a key role in pushing Mr. Trump’s agenda in Europe, promoting his brand of politics and cultivating ties with right-wing groups aligned with his movement.
Earlier this year, the Brazilian government barred another Trump envoy from entering the country, after learning that he secretly planned to visit the jailed former president and meet his son and political successor, Flávio Bolsonaro.
Last year, Mr. Trump tried to pressure Brazil to drop the case against the elder Mr. Bolsonaro, a close political ally, by using hefty tariffs and sanctions.
That strategy didn’t work, and Mr. Bolsonaro was sentenced to nearly three decades in prison for trying to cling to power after losing the 2022 election to Mr. Lula. Mr. Bolsonaro is serving his sentence under house arrest for health reasons.
