Javier Milei, president of Argentina, officially launched the campaign for the 2025 legislative elections in the province of Buenos Aires with an event held at Club Atenas in La Plata on August 14, 2025. The event marked the start of a broader tour across Buenos Aires province, with Junín as the next stop. During his speech, Milei criticized the province's governance, condemning four decades of populism and highlighting issues such as increasing disorder and abandonment. He also expressed strong opposition to the Kirchnerist political faction. The campaign event featured the presentation of La Libertad Avanza's candidates for the provincial elections scheduled for September 7, 2025. The launch drew reactions from Axel Kicillof, governor of Buenos Aires province, who questioned Milei's legitimacy in seeking votes. Separately, Luis Petri, Defense Minister and ally of Milei, confirmed his candidacy for national deputy representing Mendoza, joining Patricia Bullrich who is running for senator in the City of Buenos Aires. Virginia Gallardo was announced as La Libertad Avanza’s candidate for national deputy in Corrientes. Meanwhile, Jorge Capitanich will lead the senatorial list for the Peronist Fuerza Patria party in Chaco, which has unified to oppose La Libertad Avanza. Additionally, the Argentine justice system has initiated legal proceedings against Milei and some of his supporters over alleged threats against a journalist. Other political developments include Myriam Bregman and Christian Castillo leading the Frente de Izquierda lists in Buenos Aires City and Itaí Hagman and Taiana heading Fuerza Patria lists in the City and Province respectively.
