President Javier Milei will swear in Diego Santilli as Argentina's chief of Cabinet on Tuesday afternoon [1].

The appointment is a strategic move to stabilize the administration. By replacing Manuel Adorni, the government intends to shift its political agenda away from the judicial controversy that led to the previous chief's departure.

Santilli takes over the role following the resignation of Adorni, whose tenure ended amid a political-judicial scandal [1], [2]. The transition is designed to allow the Milei administration to distance itself from the legal complications surrounding the former official and refocus on governance.

The swearing-in ceremony is scheduled for Tuesday, May 6, 2026 [1]. Reports differ on the exact location of the event; some sources said the president received the designated minister at the Olivos presidential residence, while others said the ceremony will be held at the Casa Rosada in Buenos Aires [1], [3].

President Milei will preside over the ceremony to formally install Santilli into the position. This leadership change comes as the administration seeks to mitigate the fallout from the Adorni case, which had created growing unrest within the political sphere [2].

The shift in personnel marks a pivot in the government's communication strategy. By installing a new chief of Cabinet, the administration aims to reset its public image and move past the scandals that have characterized the recent period of Adorni's tenure [1].

The government will seek to move past the Adorni scandal.

This transition represents an effort by President Milei to perform a 'political reset.' By replacing a figure entangled in legal disputes with Santilli, the administration is attempting to insulate the presidency from judicial volatility and regain a focus on its legislative and economic agenda.
