What we know about Javier Milei’s cabinet so far

With a planned drastic reduction in Argentina’s number of ministries, the president-elect has named most of the new administration’s key players — with some glaring exceptions

Updated on December 4 at 12 p.m.

President-elect Javier Milei will take office in a week. Following a feverish back-and-forth over the most important positions in his cabinet in the past few weeks, he has now confirmed all of his ministers and some high-profile officials.

Ever since the presidential campaign began, Milei has said he will cut down the number of ministries, currently at 18, to only eight in a bid to reduce public spending. The president-elect has yet to confirm who will be in charge of the health and labor secretariats under his incoming administration.

This is what we know so far.


Luis Caputo will be Argentina’s economy minister once the new administration is inaugurated on December 10, Milei announced on November 29. He was finance minister and Central Bank chief during former President Mauricio Macri’s government. Caputo only lasted three months in the latter position, resigning amid a bank run. He is seen as one of the main drivers of Argentina’s 2018 IMF deal and one of Macri’s most trusted officials.

Former presidential candidate Patricia Bullrich will be Milei’s security minister, the president-elect’s press team announced on X (formerly Twitter) on December 1. This will be Bullrich’s second stint on the job, having held the same role during former President Mauricio Macri’s government (2015–2019).

Bullrich, who is currently PRO party president, had been in negotiations to join the incoming administration in some capacity for a few days. On November 30, she met with Milei at his Hotel Libertador headquarters and left after a little over an hour without speaking to the media. Members of her press team told the Herald they had discussed the possibility of Bullrich joining Milei’s government but did not confirm in what role.

Luis Petri, the former UCR deputy for Mendoza who ran for vice president on Patricia Bullrich’s ticket, will be Javier Milei’s defense minister, the president-elect’s team confirmed on December 4.

“We will start working today for a change that will allow us to value the role of our armed forces once again,” he vowed on an X post after the announcement.

Petri is the only prominent UCR member who publicly supports Milei.

Foreign affairs 

Diana Mondino was Milei’s prospective foreign minister for most of the presidential campaign, and he confirmed her role after winning the elections. Mondino, an economist by training, was the director of high-profile companies such as Pampa Energía, Supervielle Bank, and Loma Negra. She was also head of the Latin American region for Standard & Poor’s.

Echoing similar comments from Milei, Mondino said in November that the legalization of an organ market would be “fantastic” claiming that the president-elect’s controversial suggestion would not imply organs necessarily being sold, but rather that it would be a “transaction.”

Far-right president-elect Javier Milei said during interviews following his November 19 victory that lawyer Mariano Cúneo Libarona will be his future justice minister.

Lawyer Cúneo Libarona rose to fame for working in high-profile cases in the 1990s defending figures like former President Carlos Menem’s relatives, which involved money laundering and drug and arms dealing.

Cúneo Libarona spent a brief stint in jail in the late 1990s for allegedly helping to cover for two policemen accused of stealing evidence regarding the 1994 bombing of the AMIA Jewish community center. He was released after one month, when the policemen were acquitted.

National Treasury Attorney’s Office

In the statement announcing Bullrich’s naming as minister, Milei’s team also said that Rodolfo Barra would head the National Treasury Attorney’s Office, a division of the executive branch that represents the state in judiciary proceedings. Barra is a former Supreme Court Justice (1989–1993) who later became judiciary minister (1993–1996) during former President Carlos Menem’s administration. 

Barra was forced to resign as minister in 1996 after it came to light that, in his youth, he had been part of groups that expressed admiration for Nazism.

Interior ministry

Guillermo Francos left his role as Argentina’s Inter-American Development Bank (IDB) representative in August to join Milei’s team. He was later confirmed to be the future interior minister. His position will consist in being the link between the executive power and the provinces.

Francos had been assigned to represent Argentina at the IDB by President Alberto Fernández when he took office in December 2019, and worked on current Argentine Ambassador to Brazil Daniel Scioli’s presidential campaign as part of the Peronist Frente para la Victoria coalition in 2015.

‘Human capital’ 

Sandra Pettovello will be Milei’s minister of “human capital,” he confirmed after winning the elections. This new portfolio will combine health and labor, which will no longer be ministries in their own right.

Pettovello has degrees in journalism and family sciences. She works as a psychology consultant, although she does not have a degree in psychology.

Milei’s press office confirmed on Tuesday that Carlos Torrendell will be education secretary. Although Milei had named a labor secretary following his presidential win, the position is now vacant, as is the health secretary role. Bullrich was rumored to be appointed as labor secretary before she was confirmed as security minister.


After the elections, businessman Guillermo Ferraro said he would be Javier Milei’s infrastructure minister. He claimed that the newly formed ministry would oversee five sectors: transport, public works, energy, mining, and communications. 

Of the five sectors included within the potential infrastructure ministry, transportation and public works are currently two separate ministries. Energy and mining are secretariats within the economy ministry, while communications is a secretariat that depends on the executive branch.

Chief of staff

Engineer Nicolás Posse has been coordinating Milei’s technical teams since the campaign started earlier this year. He is in charge of designing the government plan, alongside Milei’s sister, Karina. Posse met Milei while they both worked for some of businessman Eduardo Eurnekian’s companies.

Congress leaders

Milei will propose deputy-elect Martín Menem to preside over Argentina’s Lower House, the president-elect’s team announced on December 2. In the same release, they said that Francisco Paoltroni was picked to be the Senate’s provisional president behind Victoria Villarruel.

Per the Constitution, Senator-elect Paoltroni will be second in the line of succession after Vice President-elect Victoria Villarruel, while Menem will be third.
