Now-former Minister of the Interior, Diego Santilli, is preparing to take office as the new Chief of Cabinet of Ministers in Javier Milei’s government, replacing Manuel Adorni, who submitted his resignation over the weekend. The swearing-in ceremony is scheduled for this Tuesday, June 30, at 4 PM at Casa Rosada, where the President will administer the oath for his new role within the Executive Branch.
The news was confirmed by Milei himself through his social media, where he posted: «Here alongside the new Chief of Cabinet of Ministers @diegosantilli and the Secretary General of the Presidency @KarinaMileiOk outlining the foundations for an orderly transition of the position. The swearing-in will be on Tuesday at 4 PM. MAGA. VLLC!» The tweet, accompanied by a photo of the three, dispelled any doubts about the appointment.
Santilli will retain his position as head of the Ministry of the Interior, while Ignacio Devitt, until now Secretary of Strategic Affairs, will accompany him as Deputy Chief of Cabinet. This scheme formally replicates the one led by Guillermo Francos and Lisandro Catalán, though with a more political profile. Santilli’s arrival seeks to calm waters at Casa Rosada, following tensions generated by the scandal surrounding Adorni and his asset growth, which complicated governance and the economy.
«I take on the most important challenge of my life with the commitment to continue working so that this Government keeps making history. I believe in collective projects, not individual ones. That’s why I will work as a team, alongside a great Cabinet led by President @JMilei, with a clear vision and the necessary determination to definitively pull Argentina out of the hole they left it in,» Santilli posted on his X (formerly Twitter) account.
Since taking office at the Interior Ministry in November last year, Santilli has become a key figure within the libertarian government. He maintains ongoing dialogue with the Secretary General of the Presidency, Karina Milei, and has been responsible for building bridges with governors and the opposition. His dialoguing profile contrasts with that of Adorni, who had made enemies both inside and outside the ruling party.
During Monday morning, according to official sources, the transition between the outgoing and incoming teams will take place. Santilli has already advanced that his new role includes continuing with the guidelines set by the head of state, coordinating with ministers, and implementing decisions based on what Milei says. «The cabinet is very powerful. My task is to keep working so that the reforms Milei dreams of happen,» said the new Chief of Cabinet.
Santilli’s appointment was not without controversy. Opposition sectors criticized him for holding two high-ranking positions, while the ruling party defends the measure as a way to centralize management. The fact is that the new Chief of Cabinet arrives at a crucial moment, with the economy faltering and Milei’s structural reforms in full implementation. The Adorni scandal, which included allegations of illicit enrichment, left open wounds in the governing coalition, and Santilli will have to prove he can maintain unity and advance the libertarian agenda.
The swearing-in ceremony will be this Tuesday at 4 PM, in an event that promises to be brief but laden with symbolism. With Santilli at the helm of the Cabinet, Milei seeks to make a course correction and show that his government remains firm despite the turbulence. Time will tell if the former Interior Minister is up to the challenge.

Para mí Santilli es otro ajustador de mierda que se suma al circo de Milei. Me parece que es la misma basura que Adorni, pero con mejor talle. Mientras ellos se pelean por los cargos el pueblo se muere de hambre. Esto huele a gobierno de mierda. Firme: El Tuerto de la Zurda
para mi al fin sacaron al zurdo corrupto de adorni q se llenaba los bolsillos con nuestra plata santilli va a limpiar todo como corresponde a los patiziosos de verdad vamo milei a barrer con toda la mugre 🧹💪
