BRASÍLIA, Brazil — Brazil has denied visa requests for two senior officials from U.S. President Donald Trump's administration after concluding that their planned visit was intended to cast doubt on the integrity of Brazil's electoral system ahead of the country's October presidential election, according to Brazilian officials familiar with the matter.
The officials, who spoke on condition of anonymity because of the sensitivity of the issue, said Brazil viewed the proposed visit as an attempt to influence the country's election campaign. The diplomatic dispute marks a further deterioration in relations between Brasília and Washington during an already tense election season.
According to the officials, Brazil rejected visa applications submitted for Riley M. Barnes, Assistant Secretary in the U.S. State Department's Bureau of Democracy, Human Rights and Labor, and Samuel Samson, a deputy assistant secretary. The delegation had planned to travel to Brazil in the coming days before election campaigning officially begins.
Brazilian authorities believed the purpose of the visit was to raise questions about the reliability of the country's electronic voting system, an issue that has remained politically sensitive since the 2022 presidential election. Officials argued that allowing the visit could be interpreted as foreign interference in Brazil's democratic process.
The U.S. State Department rejected suggestions that the planned trip was intended to interfere in Brazil's elections. A spokesperson said the visit would have been a routine diplomatic mission consistent with the department's broader efforts to promote democracy, human rights, and engagement with civil society around the world.
Brazil's October presidential election is expected to feature incumbent President Luiz Inácio Lula da Silva against conservative Senator Flávio Bolsonaro, the son of former President Jair Bolsonaro. Recent opinion polls show Lula maintaining a narrow lead heading into the campaign.
The controversy has revived memories of the political turmoil surrounding Brazil's 2022 election, when Jair Bolsonaro repeatedly questioned the country's electronic voting system without presenting evidence of widespread fraud. After losing that election to Lula, Bolsonaro challenged the results, and he was later convicted for plotting to overturn the outcome. He is currently serving a prison sentence under house arrest and has been barred from holding public office until 2030.
In recent weeks, Flávio Bolsonaro has also called on foreign governments to send election observers to Brazil. During a meeting with diplomats, he raised concerns about the country's voting system and incorrectly suggested that Brazil's electronic voting machines were linked to Smartmatic, a company associated with election technology in other countries. Both Smartmatic and Brazil's Superior Electoral Court have denied that the company supplied Brazil's voting machines.
Brazilian officials said the proposed U.S. visit was viewed as potentially reinforcing claims that could undermine public confidence in the electoral process. They stressed that protecting the credibility of the election remains a national priority as campaigning intensifies.
The diplomatic disagreement comes after several weeks of growing tensions between the Trump administration and the Brazilian government. Recent disputes have included trade measures imposed by Washington on Brazilian imports, as well as disagreements over the legal treatment of Jair Bolsonaro.
Political analysts say the visa rejection reflects Brazil's determination to prevent any perception of foreign involvement in its domestic political affairs. They note that election integrity has become one of the central issues in the campaign, making any outside intervention particularly sensitive.
Despite the diplomatic setback, neither government has indicated that broader bilateral relations will be suspended. However, the incident is expected to add further strain to ties between the two countries as Brazil moves closer to its October presidential election, which is widely regarded as one of the most consequential in the country's recent history.
