The announcement came one day after Manuel Adorni, Santilli's predecessor, resigned for being the target of investigations by the Argentine Justice for illicit enrichment and concealment of assets (read more below). In a statement still on Sunday, Santilli thanked Milei for the opportunity and said he will help the Argentine president to "get the country out of the hole". "I take on the most important challenge of my life with the commitment to continue working so that this government continues to make history. (...) I will give my all so that this government continues to advance in the structural reforms that Argentina has needed for decades," stated Santilli on social media. Now on g1 Investigated by the Justice, Manuel Adorni resigns The chief of staff of the Argentine government, Manuel Adorni, left the position this Saturday (27) for being involved in a scandal for alleged illicit enrichment and concealment of assets. He had also already resigned from the position of government spokesperson days earlier. Adorni himself published a resignation letter on his social media, confirming his departure. "Thank you for the trust, Mr. President. It was a true honor," wrote the now former official. Adorni is one of the figures closest to Milei and recently admitted to having hidden 500,000 dollars (about R$ 2.6 million) in his asset declarations, in a case that put him in the crosshairs of the Justice and the opposition.

However, this contradicted previous statements given by him to the Argentine Congress: in April, he stated to parliamentarians that "there was never any concealment" of his assets. The case is being investigated by the Argentine Federal Justice along with complaints about the purchase and renovation of properties for hundreds of thousands of dollars, in a scandal that gains a new chapter every week. Adorni resisted in the position with the support of the president and presented explanations considered insufficient. Milei tried to keep him until the last moment and, on Friday morning (26), during a visit to Spain, the Argentine president even stated that he would only fire him if the Justice found him guilty of corruption. In the letter, Adorni thanked Milei: “Thank you. Thank you for understanding the reasons and for understanding me: for the first time since that December 10, 2023, I am going against your wishes. Thank you for finally accepting my resignation this time.” Adorni, 46, started in the government as presidential spokesperson in 2023 and moved to the Chief of Staff's office last November.
