Despite Senate President Davi Alcolumbre's indication that he will not open a Commission of Inquiry (CPI) regarding Banco Master, senators are taking matters into their own hands by launching their own initiatives aimed at investigating the case across three fronts. This highlights the ongoing tensions within Brazilian politics and the determination of senators to address what they perceive as a significant issue of financial fraud, regardless of Alcolumbre's stance.

One of the focal points of this investigation is Daniel Vorcaro, the owner of Banco Master, who was scheduled to testify before the Senate on consecutive days in various committees. These hearings were set for the mixed CPI of INSS and the Senate Committee on Economic Affairs (CAE). However, Vorcaro has chosen not to attend these sessions, citing logistical difficulties posed by a Supreme Court minister's refusal to authorize the use of a private jet for his travel to Brasília. This refusal and Vorcaro's absence illustrate the complexities and challenges senators face in pushing forward their inquiries.

The involvement of the Supreme Court, especially through Minister André Mendonça, adds another layer to this situation, as Mendonça, who has taken over the case from former Justice Dias Toffoli, ruled that Vorcaro is not obligated to appear before the CPI. This backdrop of legal maneuvering and political tension foreshadows a protracted battle within the Senate, as senators strive to hold accountable those involved in potential financial misconduct, indicating that the investigation will continue despite the obstacles presented by the Senate leadership.
