The Argentine judiciary authorized Brazilian President Luiz Inácio Lula da Silva to visit former Argentine President Cristina Fernández de Kirchner, who has been under house arrest in Buenos Aires since June 17, 2025, following a corruption conviction. Kirchner was sentenced to six years in prison for corruption-related charges. Lula arrived in Buenos Aires on July 2 to participate in the Mercosur summit and visited Kirchner on July 3 at her residence in the Constitución neighborhood. The visit was described as an act of political solidarity, with Lula expressing his longstanding friendship with Kirchner and encouraging her to continue her fight with firmness. The authorization for the visit was granted after Kirchner's request to the Argentine court, and the meeting took place with police escort. Lula's visit attracted attention as a demonstration of support for Kirchner amid her legal and political challenges.
