Argentina’s ruling party, La Libertad Avanza (LLA), is experiencing growing internal turbulence.

Alongside a series of corruption scandals involving senior officials, which are making some people at the top uncomfortable, a previously subdued power struggle among figures closest to President Javier Milei has now erupted into public view on social media.

Over the weekend, the clashes reached boiling point after presidential advisor Santiago Caputo — one corner of Milei’s self described “iron triangle”, along with himself and his sister, Presidential Secretary Karina Milei — made a direct accusation on X against Karina Milei’s right-hand man.

Caputo — second nephew of Economy Minister Luis “Toto” Caputo — accused the head of the Lower House Martín Menem of owning an X account that constantly made negative comments about him and people under his purview, and shared private information.

Menem denied the accusation.
