"Lava Jato," or "Operation Car Wash," is a large-scale investigation that began in Brazil in 2014. It uncovered widespread corruption involving Petrobras, the state-controlled oil company, and various construction firms. The operation revealed a complex scheme of bribery and money laundering that implicated numerous politicians and business leaders. The investigation led to significant legal actions, including the arrest of high-profile figures, such as former President Luiz Inácio Lula da Silva. "Lava Jato" has had a profound impact on Brazilian politics and society, raising awareness about corruption and prompting calls for reform in governance and accountability.
