The Brazilian opposition parties are increasing their efforts to compel Senate President Davi Alcolumbre to initiate the CPMI concerning the Master case, in light of Daniel Vorcaro's recent arrest. There is a growing belief among lawmakers that Alcolumbre will struggle to maintain his position against the establishment of this inquiry. Both members of the PL and Novo parties are especially vocal, emphasizing that the Senate's procedural rules necessitate the reading of the CPMI installation during the first session of the National Congress, which Alcolumbre has yet to execute.

Despite the mounting pressure, Alcolumbre remains hesitant to call for a session that would allow for the CPMI's formation, suggesting he is attempting to avoid entertaining the issue, which may also complicate the renewal of the CPMI concerning the INSS. Opposition figures have vowed to publicly challenge Alcolumbre, leveraging social media to amplify their demands for adherence to Senate regulations. One senator privately remarked that in order to deny the installation of the CPMI, Alcolumbre would have to perform significant political gymnastics.

The demand to activate the CPMI has gained considerable momentum, amassing 278 signatures in early February, indicating significant political backing. The unfolding situation suggests that the opposition is prepared to escalate their efforts if Alcolumbre continues to resist their calls for transparency regarding Vorcaro's case and the broader implications of the Master scandal. This dynamic reflects ongoing tensions within the Brazilian political landscape and highlights the importance of accountability among elected officials.
