Presidency Secretary and President Javier Milei’s sister Karina Milei called to “fill Congress” with libertarian deputies and senators and hinted at a potential candidacy ahead of the upcoming 2025 legislative elections.

“I will always be where my brother needs me,” she said on Thursday during an end-of-year rally from ruling party La Libertad Avanza (LLA) in response to someone in the public who shouted calling for her to be a candidate. Milei is the national party leader.

“Like Javier always says, we are just but a mere instrument for the cause,” Karina Milei continued. “We are willing to give our lives to change Argentina’s reality. That was our promise, and for the Milei siblings, promises have to be kept.”

The event gathered LLA activists and political leaders from Buenos Aires city and Buenos Aires province. The party heads from each of those districts signed a cooperation agreement devoted to designing public policies.

LLA Vice President and Lower House head Martín Menem, Buenos Aires province LLA leader Sebastián Pareja, BA city LLA President Pilar Ramírez and Presidential spokesman Manuel Adorni shared the stage with Milei at the Gran Rivadavia theater. Press was not allowed in.

During her speech, Milei recalled her brother’s beginnings as national deputy in 2021 and said that all those who had predicted the LLA government “would only last a month” are now “very scared seeing the results” of their first year in office. “If we managed to do so much with everything against us, imagine what we can do with everything in our favor. We will be unstoppable.”

Milei also called on libertarian activists to “match the president’s faith and conviction, because he is giving his life to move Argentina forward.”

Karina is President Milei’s right hand and the person he trusts the most, not just as his sister, but as a political advisor and guide. He calls her “El Jefe,” the Spanish masculine form for “The Boss.” As soon as he became president, he appointed her in the crucial role of Presidency Secretary despite her political inexperience. As his go-to person, he tasked his sister with leading the newly created LLA party — which only existed as a coalition until not long ago.

The event showcased LLA’s growing distance with their political ally party PRO. The venue was located in Buenos Aires city, the district where PRO is strongest, and happened days after PRO leader and former President Mauricio Macri hinted in a party meeting that they will not form an alliance with LLA to compete in the 2025 election.

The growing rift between the two factions added another chapter on Thursday with the appointment of Diego Kravetz as second in command of the intelligence service SIDE. Kravetz had been serving as the Buenos Aires City security secretary, his latest post in a series of positions he has held in PRO administrations.
