Argentina's Senate on Thursday approved the appointment of María Verónica Michelli as a judge of Federal Oral Court No. 3 in La Plata, a nomination President Javier Milei had tried to block because she is the sister-in-law of journalist Hugo Alconada Mon, of the newspaper LA NACION. The nomination was approved on the floor by 44 votes to 18 —all the negatives from the ruling party— with two abstentions, in a session that exposed a rift within the governing bloc.

Argentina's economy minister, Luis Caputo, ruled out on Tuesday that Kirchnerism could win the 2027 presidential election and, in particular, that the governor of Buenos Aires province, Axel Kicillof, could reach the presidency.

The Federal Criminal Cassation Chamber of Argentina on Thursday rejected the extraordinary appeals filed by former president Cristina Fernández de Kirchner, her children Máximo and Florencia, and businessman Lázaro Báez against the confiscation of 111 assets ordered as part of the Vialidad case.

The governments of Argentina, Bolivia, Chile, Ecuador, and Peru on Thursday signed in Santiago a joint cooperation agreement against transnational organized crime, in a meeting convened by the Chilean government of President José Antonio Kast and attended by five foreign ministers, four security ministers, and one interior minister.

Minutes of the Argentine Submarine Force Advisory Council signed by fourteen navy captains on 30 April 2017, seven months before the implosion of the ARA San Juan in the South Atlantic, have become central evidence in the ongoing oral trial before the Federal Oral Court of Santa Cruz, based in Río Gallegos. The document, cited by the Argentine outlet Infobae, details the technical issues outstanding and the operational restrictions affecting the submarine before its final mission, and constitutes one of the central elements of the debate over the eventual criminal responsibility of the four former senior naval commanders charged in the case.

In his address, Goss defended the right to self-determination of the inhabitants of the archipelago, reiterated the Legislative Assembly's invitation for the body to send a visiting mission to the Islands, and questioned Argentina's failure to comply with the bilateral cooperation package agreed with the United Kingdom in September 2024.

A 63-year-old Argentine tourist, identified as Eduardo Ignacio, was arrested on Sunday in the Brazilian state of Minas Gerais on racial discrimination charges after photographing and filming a 7-year-old Black boy aboard a tourist train, and sharing the images in a messaging group with racist comments that included the phrase: “I can take him as a slave.” The case, recorded on the steam train that connects the municipality of São João del-Rei with the historic city of the same name, raises to three the racism episodes involving South American tourists in Brazil over the past five months.
