Donald Trump may reject Lula victory in Brazil election, former White House adviser warns
Nick Zimmerman warns that Washington could use non-recognition to force concessions or levy sanctions on Brazil.
A former White House adviser has warned that US President Donald Trump may refuse to recognise the result of Brazil’s presidential election if the leftist incumbent, Luiz Inácio Lula da Silva, wins a tight race.
Nick Zimmerman, who served as director for Brazil and the Southern Cone on the National Security Council under Barack Obama, said Trump’s interference in Brazilian politics is unprecedented. Speaking to the Brazilian newspaper Folha de S.Paulo, Zimmerman warned that if Lula wins a narrow victory, Washington could withhold recognition as a tool to demand policy concessions or slap Brazil with new economic sanctions in 2027.
The warning comes as Brazil counted votes in a tense first-round election on Sunday, 4 October 2026. Early tallies from conservative southern states gave Senator Flávio Bolsonaro, the 45-year-old son of jailed former President Jair Bolsonaro, a strong start. With 65% of the votes counted, the younger Bolsonaro held 49.58% to Lula’s 42.25%, though the polling agency Datafolha projected that neither would cross the 50% threshold needed to avoid an October 25 runoff.
Allegations of foreign interference
The election has been overshadowed by allegations of foreign meddling. Andrei Rodrigues, the director general of Brazil's Federal Police, confirmed on Sunday that detectives are actively investigating potential US interference. The inquiry follows reports that the US State Department diverted $1 million to finance local groups aiming to destabilise the Brazilian judiciary. The US government has denied any meddling.
Zimmerman argued that Trump's administration has already tried to tilt the scales, pointing to recent US sanctions on Supreme Court Justice Alexandre de Moraes and the designation of major Brazilian drug gangs as terrorist organisations. If Flávio Bolsonaro wins, Zimmerman expects Trump to demand that Brazil limit China’s access to its infrastructure and critical minerals.
High stakes and legal battles
The political stakes are exceptionally high. The challenger's father, Jair Bolsonaro, is currently serving a 27-year sentence under house arrest for plotting a coup after his 2022 defeat. Meanwhile, Flávio Bolsonaro himself is under federal investigation for money laundering, a charge he denies. Lula, now 80 and seeking a fourth term, has framed the election as a battle to protect democracy.
Despite the high tension, the head of Brazil’s electoral court, Kassio Nunes Marques, said voting had proceeded smoothly. International risk monitoring teams, he added, had detected no threats to the process.
