Argentine President Javier Milei insulted Brazilian Supreme Court Minister Alexandre de Moraes during a political convention in São Paulo on July 25 [1].

The incident marks a significant diplomatic escalation between two major South American neighbors and highlights the friction between Milei and Brazil's judiciary.

Milei spoke at the national convention of the Partido Liberal (PL), an event used to formalize the candidacy of Flávio Bolsonaro [2]. During his appearance on stage, Milei referred to Minister Moraes as "lixo careca" [3].

The outburst followed a decision by Brazilian courts to bar the Argentine president from visiting former President Jair Bolsonaro, who is currently jailed [4]. Milei used the platform to vent his frustration regarding the restriction on his movements and the judicial actions taken by the court.

Edson Fachin, the president of the Supremo Tribunal Federal (STF), responded to the remarks. Fachin said the comments were "desrespeitoso" [5]. He said the language used by the Argentine leader is "incompatível com a civilidade" [6].

The convention in São Paulo [7] served as a gathering for right-wing allies in the region. In addition to his attacks on the judiciary, reports indicate Milei also targeted other Brazilian political figures during the event [8].

Despite the diplomatic tension, the STF has not announced formal legal repercussions for the insults. The clash underscores the ongoing ideological divide between Milei's administration and the Brazilian legal establishment, a tension that has grown since the Argentine president's alignment with the Bolsonaro family.

"lixo careca"

This confrontation signals a deterioration in diplomatic decorum between Argentina and Brazil, shifting from policy disagreements to personal attacks on state institutions. By targeting a sitting Supreme Court minister during a foreign political rally, Milei is leveraging his alliance with the Brazilian right to challenge the legitimacy of the Brazilian judiciary on an international stage.
