President Javier Milei confirmed former Interior Minister Diego Santilli as the new chief of staff, replacing Manuel Adorni [1].
The appointment signals a strategic shift toward a more political management style. Milei aims to improve relations with allies and speed up the legislative approval of his reform agenda [2, 4].
Milei said the decision on June 27, 2026 [1]. The transition follows the resignation of Manuel Adorni from the position [5]. While some reports indicate the confirmation occurred during a meeting in Olivos, other sources place the announcement at the Casa Rosada in Buenos Aires [1, 3].
Santilli is expected to bring a different approach to the role of jefe de Gabinete. Milei said, "Tiene músculo" [2]. This perceived strength is intended to bridge gaps between the presidency and the PRO party, which has shown support for the move [3].
The formal transition is nearly complete. The oath of office for Santilli was scheduled for Tuesday, June 30, 2026 [1].
This change in leadership comes as the administration seeks to solidify its coalition in the legislature. By installing a figure with deep ties to the PRO, Milei is pivoting away from the more technical or communicative focus of Adorni toward a political operative capable of negotiating complex legislative packages [2, 4].
“"Tiene músculo"”
The replacement of Manuel Adorni with Diego Santilli represents a move toward pragmatism over pure ideology in the Casa Rosada. By selecting a leader with established political weight and ties to the PRO, Milei is attempting to reduce friction with his allies to ensure his economic and structural reforms do not stall in congress.
