Brazil’s Supreme Court has unsealed thousands of pages from the Banco Master investigation, including a July probe into Senator Flavio Bolsonaro over suspected corruption, money laundering and tax evasion. The case concerns alleged transfers of about $12 million from former Banco Master chief executive Daniel Vorcaro to a U.S.-based fund linked to Flavio’s brother, Eduardo Bolsonaro, reportedly to finance Dark Horse, a film portraying former President Jair Bolsonaro favorably. Federal Police estimate the wider Banco Master fraud at roughly $2.3 billion, with about 800,000 bank clients among the alleged victims. The disclosures have deepened a dispute between Justices Andre Mendonca and Alexandre de Moraes and added pressure to Brazil’s presidential campaign, in which Flavio is challenging incumbent Luiz Inacio Lula da Silva on October 4. Both candidates have called for a full investigation, while the court is due to decide next week whether to investigate de Moraes.
