1. The fall of Adorni: three months that shook the government

On Friday, June 27, 2026, Manuel Adorni published on his social networks a letter of resignation from the position of Chief of Staff with a single final word: "End." With that laconic closure, the most turbulent cycle of the Milei administration to date ended: more than three months of heritage scandals, questionable trips, judicial investigations and a war of attrition that paralyzed the government's legislative agenda and fractured key alliances.

Adorni's departure was not a resignation in the strict sense of the term. According to sources with access to the presidential decision-making circle, it was the President's own entourage that asked him to step aside. Adorni resisted for more than three months protected by the explicit support of Javier Milei, who until Friday, from Madrid, insisted that he would not displace him if the Justice did not certify corruption.

The chronology of a collapse foretold

The plot of the Adorni scandal began in Queens, New York, with an innocent image. A photo of Adorni with his wife Bettina Angeletti in the Lubavitcher cemetery, during the presidential procession of Argentina Week, lit the first fuse.

2. The scandal that paralyzed a government

The Adorni case far exceeded the judicial file. In political terms, the damage was systemic: the government's legislative agenda was paralyzed for weeks because the opposition blocs – and some allies – conditioned any progress in Congress on the departure of the Chief of Staff.

In the Senate, the ruling party was forced not to give a quorum to block a request for Adorni's interpellation, but that temporary halt had an expiration date: Wednesday, July 1, when the Constitutional Affairs Commission was scheduled to deal with the issue. The result would have been unfavorable to him.

The departure of Esteban Bullrich from the PRO – a moderate figure in the party – was another collateral damage. The former Buenos Aires senator announced his departure by coining the phrase that defined the moment: with Adorni we lower the last flag.

3. Diego Santilli: the tightrope walker who reaches the center of the board

It is not a surprising name. When Adorni's collapse became irreversible, Interior Minister Diego Santilli — nicknamed "El Colo" — had been the strongest candidate for succession for weeks. Not by improvisation, but by patient and deliberate political construction.

A profile designed for consensus

Santilli has something that is lacking in libertarian internal politics: simultaneous arrival with all the relevant sectors of power without having broken with any of them. He maintains a fluid relationship with Karina Milei, the secretary general of the Presidency. He is in tune with presidential advisor Santiago Caputo. And he has the explicit support of Patricia Bullrich, head of the ruling bloc in the Senate.

This equanimity is not accidental. Santilli arrived at the Ministry of the Interior in November 2025 after one of the most notable electoral comebacks in recent Buenos Aires political history: when José Luis Espert fell from the official list due to his links to businessman Federico Machado, Santilli was at the head of a candidacy that many thought was lost, and he won.

The meeting that set the course

On Friday night, in total secrecy, Karina Milei, Santilli and Martín Menem met at the Casa Rosada. That meeting ended up setting the course: it was in that area that the offer to the Minister of the Interior was formally advanced. According to those close to the Buenos Aires politician, he was not enthusiastic — the position complicates his projection as a candidate for governor in 2027 — but no one in the government believes that he can say no to the President.

4. Ministerial restructuring: what changes and what remains

Santilli's arrival as Chief of Staff is not a simple change of names: it implies a significant reconfiguration of the organizational chart of the libertarian government, with a direct impact on the Ministry of the Interior and the architecture of power around the Casa Rosada.

Interior returns to the orbit of the Headquarters

The first relevant structural change is the reintegration of the Ministry of the Interior under the wing of the Chief of Staff, reversing the autonomy that this portfolio had acquired since Santilli led it. The model once again resembles the previous scheme: centralized political coordination, as it worked with Guillermo Francos and Lisandro Catalán in the first stage of the government.

Changes in presidential communication

The redesign of the political area already began before the formal announcement. The resignation of Press Secretary Javier Lanari and the appointment of economist Adrián Ravier as the new presidential spokesman were interpreted as clear signs that the reorganization was underway. Fabián Rodríguez, Horacio Marín's former spokesman at YPF, took over as Secretary of Communication and Press.

The new scheme seeks to separate the functions of ministerial coordination – which will fall on Santilli – from those of political communication, avoiding the concentration of power that characterized the Adorni cycle, where the Chief of Staff accumulated roles until he was overexposed.

What Santilli will have to manage from day one

▸ Unblock the paralyzed legislative agenda, including the Private Property Law.

▸ Coordinate with governors and financial advances to the provinces to maintain political balance.

▸ Manage the relationship with the PRO and the opposition dialogue blocs.

▸ Contain the deterioration of the government's image after the impact of the Adorni case.

▸ Organize the presidential communication structure during the transition period.

5. The political cost of the Adorni case for the libertarian project

Beyond the judicial files, the political impact of the Adorni case on Milei's government was profound and multidimensional. The administration that came to power promising to exterminate the "caste" and corruption, had to live for more than three months with a Chief of Staff investigated for illicit enrichment.

The President tried to shield his official with unusual resources: posters, public statements, joint appearances at official events. From Spain, he went so far as to say that media coverage had violated the limits of the human. But the accumulated wear and tear was impossible to stop.

The final pressure to remove Adorni came from several simultaneous fronts: the imminence of the interpellation and motion of censure in the Senate, the advance of the Justice towards a possible summons for questioning, the polls that showed a drop in the presidential image, and the explicit warning of Mauricio Macri that the PRO would vote for the impeachment if the Government did not act.

6. Political reactions: between relief and caution

The confirmation of Adorni's departure and the appointment of Santilli generated disparate reactions on the Argentine political chessboard. Within the ruling party, the news was received with relief in most sectors. In the opposition, with a mixture of satisfaction with the result and skepticism about whether change will be enough.

Within the Government

✅ Patricia Bullrich, head of the bloc in the Senate, was one of the main promoters of the departure and supports Santilli's arrival.

✅ Martín Menem, president of the Chamber of Deputies, participated in the decisive meeting on Friday night.

✅ Santiago Caputo confirmed his agreement with the designation, which marks a moment of relative peace in the "iron triangle".

✅ Karina Milei personally coordinated the details of the ministerial transition.

From the opposition

🔵 Several blocs had conditioned their support for the reforms on Adorni's departure. The new situation opens a window for negotiation.

🔵 The promoters of the interpellation said that Adorni's resignation does not close the judicial files, which continue.

🔵 The dialogue opposition will evaluate Santilli's first moves to define his legislative position.

7. Analysis: can Santilli stabilize management?

The question that all political actors in Buenos Aires are asking themselves this Sunday, June 28, is whether Diego Santilli has the capacity and capital to stabilize an administration that has been accumulating turbulence for several months.

The tentative answer is that it has better conditions than its predecessor to try, but it also faces its own restrictions. The Chief of Staff who arrives is not a man from La Libertad Avanza: he comes from the PRO, has a Peronist history and his electoral base is in the province of Buenos Aires. That heterodoxy can be an asset to negotiate with governors and opposition sectors, but also a source of tension in a political space that values ideological purity.

From the institutional point of view, the position of Chief of Staff has in the Argentine Constitution an explicit role of coordination with Congress and political accountability. The fact that this role is now occupied by an operator with legislative and territorial experience – rather than a media spokesperson – represents, in itself, a turn towards a more pragmatic management.

The big question in the medium term is whether Santilli accepted the Cabinet Chief as a definitive political destiny or as a stage of service within a trajectory that points to the Buenos Aires Governorship. That ambiguity can condition their internal authority and their ability to lead ministerial coordination with the energy and commitment that the moment demands.

8. Conclusion: A change of helm with open-ended questions

The departure of Manuel Adorni and the arrival of Diego Santilli as Chief of Staff marks a turning point in Javier Milei's administration. It is not a simple change of names: it is evidence that the government has had to double down in the face of the accumulated pressure of politics, justice and public opinion.

The President, who insisted until the last moment on defending Adorni, gives in to a reality that his own allies clearly pointed out to him: the permanence of the Chief of Staff under investigation was a burden that compromised not only the image of the Government, but also his own ability to govern.

Santilli arrives with political capital, territorial experience and the simultaneous confidence of the most relevant sectors of the official space. But the challenge ahead is enormous: to rebuild the political coordination of a government that has lost time and alliances, while maintaining the economic course that is the main asset of the libertarian project.

Political Argentina is rarely linear. This Sunday, with Santilli's appointment still hot, the questions that remain open are as important as the certainties. And the history of these months teaches that in the Milei era, everything can change faster than any chronicler can write.
