"Operation Car Wash" is a large-scale investigation that began in Brazil in 2014, focusing on a massive corruption scheme involving the state-controlled oil company, Petrobras. The operation revealed how politicians, business executives, and construction companies colluded to inflate contracts and siphon off billions of dollars. The investigation led to numerous arrests and convictions, including high-profile figures such as former President Luiz Inácio Lula da Silva. It also sparked widespread protests and discussions about corruption in Brazil, significantly impacting the country's political landscape and public trust in government institutions.
