In Argentina, President Javier Milei ordered a restructuring of security at the Quinta de Olivos presidential residence, tasking the Casa Militar with full responsibility for the site and temporary residences within 60 days to increase efficiency.

The III Meeting of the Interior Security Council convened in San Juan, led by Vice Governor Fabián Martín and National Security Minister Alejandra Monteoliva, to unify operational and preventive criteria across jurisdictions. Participants, including officials from Chubut, discussed provincial investments in video surveillance and technological integration. Key agenda items included controlling unauthorized communications within penitentiary establishments to prevent criminal coordination via mobile phones, as well as addressing the mental health and suicide prevention policies for security force members.

In Chile, the government maintained its existing communication model despite pressure from ruling coalition parties to appoint a dedicated spokesperson. Meanwhile, former Public Security Minister Trinidad Steinert faced scrutiny from an investigative commission in the Chamber of Deputies following her fourth absence from a hearing regarding executive actions and probity standards during her tenure. The commission has requested that Steinert and former Undersecretary Ana Victoria Quintana set a new date for testimony and plans to summon current Minister Martín Arrau.
