Marco Aurélio de Carvalho, the legal advisor for Fábio Luís Lula da Silva (Lulinha), revealed that Lulinha traveled to Portugal with Antônio Carlos Camilo Antunes, known as Careca do INSS, who is currently under investigation for significant frauds within the National Institute of Social Security (INSS). This admission marks the first time Lulinha's defense has acknowledged any connection to Careca, who has been incarcerated since September of the previous year. Despite this acknowledgment, Carvalho maintains that Lulinha did not engage in fraud, was unaware of any wrongdoing, and did not receive any misappropriated funds from the INSS.

The ongoing investigation into the fraudulent activities at the INSS, known as Operation Sem Desconto, was initiated by the Brazilian Federal Police in April 2025 and further scrutinized by the Mixed Parliamentary Commission of Inquiry (CPMI). This investigation centers around allegations of embezzlement involving retirement and pension funds at the INSS, raising significant concerns over corruption within the Colombian system. The timing of Lulinha's trip to Portugal in November 2024, specifically at the invitation of Careca, raises questions about the extent of their relationship and potential implications for the ongoing inquiry.

The developments come as public trust in government institutions wanes, particularly regarding social security and welfare programs. This incident underscores the need for transparency and accountability in public office holders and their connections to influential lobbyists, especially concerning sensitive issues affecting many Brazilian citizens who rely on the integrity of social security institutions. As the investigation unfolds, it remains to be seen how these revelations will impact both Lulinha and President Lula's administration.
