Minister André Mendonça has recently allowed the INSS Parliamentary Commission of Inquiry (CPI) to access classified data related to Daniel Vorcaro, the owner of Banco Master. This decision counters an earlier resolution by former rapporteur Minister Dias Toffoli, who had previously restricted access to these documents by sending them to the Senate presidency. The CPI is investigating serious allegations of fraud involving a significant number of retirement and pension contracts associated with Banco Master.

In December 2025, the CPIs mixed committee had approved the release of fiscal, banking, and telecommunication data of Vorcaro. However, rather than being directly sent to the CPI, these sensitive documents were deferred to the Senate presidency. With the intervention of Mendonça, the data will now be forwarded to the Federal Police, who will subsequently share it with the commission. This move is seen as crucial for the CPI's efforts to scrutinize up to 250,000 loan contracts that were suspended by the INSS due to apparent missing information.

The INSS CPI's inquiry aims to uncover the extent of fraud concerning these suspended contracts linked to Banco Master. Although Vorcaro was scheduled to appear before the CPI on Monday, December 23, members indicated he would no longer attend, suggesting insights might be losing momentum unless new evidence from the recently released data aids the investigation. Mendonça's decision highlights an ongoing commitment to transparency and accountability in dealing with high-stakes financial misconduct in Brazil's pension system.
