President Javier Milei has chosen Interior Minister Diego Santilli to become his new chief of staff, following the resignation of Manuel Adorni amid growing accusations of illicit enrichment and corruption.

Santilli will remain as interior minister on top of his new role. He will be formally sworn in on Tuesday at 4 p.m.

“Here we are, with new Chief of Staff Diego Santilli and Presidency Secretary Karina Milei, outlining an orderly transition for his role,” Milei wrote on X on Sunday night, confirming the rumors that Santilli would replace Adorni.

The post came one day after Adorni announced his long-awaited resignation with an open letter to the president, in which he denied the accusations and thanked Milei for his unwavering support.

Milei also confirmed Adorni has stepped down from the board of directors of state-controlled oil company YPF.
