Minister André Mendonça has been assigned to oversee investigations into Banco Master, taking over from Dias Toffoli, amid allegations of fraud both in the financial system and in the granting of social security loans through the INSS. This dual role places him as the relator of a critical inquiry regarding a fraudulent scheme affecting INSS beneficiaries. The move has received a positive response from members of the CPMI, who anticipate that Mendonça’s involvement will increase support from the Supreme Federal Court for their ongoing investigations into the bank's operations.

However, the appointment has sparked tension within the political group known as Centrão, highlighting a divide among legislators concerning the investigations' implications. The president of CPMI, Carlos Viana, expressed optimism that Mendonça's involvement will strengthen the commission's effectiveness by potentially restoring access to critical documents that were previously withheld. These documents pertain to Daniel Vorcaro and his bank, which were transferred away from the CPMI by Toffoli, raising concerns over transparency and cooperation between branches of government.

The expectation now rests on Mendonça to handle not only the sensitive nature of the investigations but also to manage the political nuances that come with them. His recent completion of a report concerning the responsibilities of social media adds to the scrutiny and weight of his new responsibilities, making the dynamics in Congress increasingly complex as stakeholders assess the political repercussions of these investigations.
