Brazil's Senator Flávio Bolsonaro is facing an investigation by the Supreme Court over allegations that he received 61 million reais (about $12 million) from Daniel Vorcaro, a former banker linked to Banco Master, a now-defunct bank. The funds are said to have been used to finance a movie about Flávio's father, former President Jair Bolsonaro. The Supreme Court recently released documents confirming the ongoing investigation, which has raised concerns about its potential impact on Flávio Bolsonaro's presidential campaign, which is set to begin in October. He is currently running closely against President Luiz Inácio Lula da Silva in the first round of elections scheduled for October 4. The allegations were first revealed in May, and Flávio Bolsonaro has consistently denied any wrongdoing. During a campaign event in Manaus, he claimed the money came from private investors interested in funding the film. Daniel Vorcaro, who was arrested in March, is accused of misleading Banco Master's 800,000 clients, including several state government pension funds, into making dubious investments. This led to the loss of hundreds of millions of dollars for those clients. Vorcaro is one of several high-profile individuals involved in the Banco Master scandal, which has implicated numerous officials in Brazil. The investigation into Flávio Bolsonaro was initiated in July by Supreme Court Justice André Mendonca, at the request of Brazil's federal police. Critics, including allies of President Lula, have suggested that Mendonca, who was appointed to the court by Jair Bolsonaro, may be biased in favor of Flávio Bolsonaro. The Supreme Court documents were released at the request of Chief Justice Luiz Edson Fachin, who aimed to resolve internal political tensions within the court and increase transparency in the broader Banco Master investigation. Brazil's federal police estimate the total fraud committed by Banco Master at around 12 billion reais (approximately $2.3 billion). The bank, which had assets exceeding $16 billion, was shut down by Brazil's Central Bank in November. The case has drawn significant public and political attention, highlighting the deep entanglement of high-ranking officials in the financial scandal. As the investigation continues, it may influence the upcoming presidential election and further complicate the political landscape in Brazil.
