Fábio Luís Lula da Silva, commonly referred to as Lulinha, is under scrutiny in an investigation by Brazil's Federal Police regarding potential fraud within the National Institute of Social Security (INSS). The investigation has uncovered messages exchanged between two individuals who are also under investigation, which mentioned Lulinha's name and included testimonies concerning his possible involvement. These findings prompted the Federal Police to request the Supreme Federal Court (STF) to authorize the lifting of Lulinha's banking, tax, and telematics confidentiality, a request approved by Justice André Mendonça in January.

In addition to the ongoing police investigation, Lulinha has become a subject of interest for a Parliamentary Commission of Inquiry (CPMI) examining related fraud allegations. Tensions were high during the CPMI session when the vote to lift Lulinha's confidentiality protections was approved, evidenced by chaotic interactions among parliament members. The investigation is part of a broader examination of various interconnected schemes involving several associations and unions linked to the INSS, collectively referred to as the "Operation Without Discount," conducted in April 2025.

The implications of these allegations against Lulinha not only threaten his personal and professional reputation but also could potentially impact the broader political landscape in Brazil, particularly for his father, President Lula, whose administration may be scrutinized amidst ongoing investigations and public concern regarding political corruption and accountability. As this investigation unfolds, close attention will be paid to its outcomes and the potential for legal repercussions for those involved, including the high-profile figures in Brazil's political sphere.
