Last week, federal police sought permission to open an ​investigation into Fabio Luis Lula da Silva, known as "Lulinha," for alleged influence peddling and corruption on behalf of businessman Antonio Carlos Camilo Antunes. "I will not use my position to protect him," Lula told the Inteligencia Ltda. The investigation into Fabio Luis ‌has not yet been formally opened, a federal police ​source said. Asked about his son in a February interview with news outlet UOL, Lula said he had confronted Fabio Luis ​about the INSS case. If you haven't, defend ​yourself," Lula told UOL.
