Luis Caputo, a former finance minister and ex-head of the central bank under former Argentine President Mauricio Macri, became economy minister. The Ministry of Security was headed by Patricia Bullrich, who ran for the post of head of state but failed to make it to the second round of voting. She has already held the post of security minister in Macri's government. Luis Petri, who ran for vice president, became minister of defense.
The Foreign Ministry was headed by Diana Mondino. The post of justice minister was taken by Mariano Cuneo Libarona, a well-known lawyer who defended a number of politicians, as well as relatives of former President Carlos Menem, whom Milei considers the best head of state in the history of Argentina.
Guillermo Ferraro became minister of infrastructure. His department will unite a number of areas, including transport, public works, mining and communications. The Ministry of Human Capital, which will focus on education, culture, labor market and social policy, was headed by Sandra Pettovello.
The post of minister of health went to cardiologist Mario Russo, while Guillermo Francos held the post of interior minister. The cabinet of ministers was headed by Nicolas Posse, who worked together with Milei in Corporacion America, which, among other things, manages all the country's airports.
In addition, Milei appointed his sister, Karina, as head of his secretariat, despite the fact that a decree signed by Macri in 2018 prohibits the president's relatives from holding government positions.
