In May 2025, former São Paulo governor João Doria reached out to banker Daniel Vorcaro, cautioning him about negative rumors related to himself and Banco Master that were circulating. In their messages, Doria expressed concern about the implications of these rumors and advised Vorcaro to respond with 'balance and consideration,' emphasizing that silence was not an option. He proposed to meet for coffee to discuss the situation further.

The exchange took place against the backdrop of an ongoing investigation dubbed Operation Compliance Zero, which led to Vorcaro's preventive detention on suspicion of attempting to obstruct the investigations. The messages, which were retrieved from Vorcaro's cell phone during a police operation, highlight Doria's proactive approach to managing potential fallout from the allegations.

Doria's communications suggest a strategy of public relations management in response to emerging issues that could impact both his and Vorcaro's reputations. The case underscores ongoing scrutiny of banking practices in Brazil and raises questions about the ethical dimensions of such preemptive advisories amidst serious investigations. Doria’s spokesperson confirmed that this message exchange occurred before any formal inquiries were initiated, indicating a possibly complex interplay between public figures and the financial industry during sensitive investigations.
