President Luiz Inácio Lula da Silva’s election coalition filed a petition with Brazil’s Superior Electoral Court on 23 September, alleging that foreign intervention and abuses of economic and political power could benefit presidential candidate Flávio Bolsonaro. It seeks the cancellation of Bolsonaro’s and his running mate’s candidacies, or their election certificates if they win, as well as eight-year bans on Flávio and his brother Eduardo. These are remedies the coalition has requested in its initial petition. [2]
The accusation has a concrete political backdrop. In July 2025, a US executive order imposed an additional 40% duty on certain Brazilian products and explicitly criticised the prosecution of former president Jair Bolsonaro, Flávio’s father. It also claimed that Brazil’s actions threatened its ability to hold a free and fair presidential election in 2026. That documents US economic pressure tied to Brazilian political and judicial affairs; it does not, by itself, show that Washington coordinated with Flávio’s campaign. [4]
Lula has accused members of the Bolsonaro family of encouraging US involvement. The family has denied the allegations. In September, Reuters reported that Brazilian intelligence officials had briefed visiting French and German officials on alleged US and Russian interference. French agencies confirmed their participation in the visit, not the interference claims; the US State Department had previously denied seeking to interfere in Brazil’s elections. [11] [12] [8]
Washington offers a separate explanation for a later tariff measure. In July 2026, the US trade representative announced a 25% tariff on certain Brazilian goods under a different law, citing an investigation into trade and regulatory practices. Flávio Bolsonaro had publicly opposed the proposed new tariffs. A survey reported by Reuters found more respondents saying the tariffs had swayed them towards Lula than towards Flávio, though those answers do not establish how anyone will vote. [5] [11]

Questions have also been raised about private contacts around Flávio’s campaign. Folha de S.Paulo reported that people linked to the US-based Rockbridge network had provided advice or services; the campaign denied receiving foreign money or infrastructure, and individuals named in the report disputed aspects of the account. Contacts and disputed services are distinct from a finding that the US government funded the campaign. [9]
