Diego Valenzuela, former mayor of Tres de Febrero, made a political shift from the PRO party to the Libertad Avanza party in July of the previous year. He was on the top of the list for his new party during the Buenos Aires provincial elections in September, winning his seat as a senator. However, shortly after his election, he requested a leave of absence hoping to secure a role as the head of the intended new Migration Agency under the national Ministry of Security. Unfortunately, his appointment became embroiled in internal disputes within the ruling coalition, ultimately leading to its cancellation.

Official sources have confirmed to Clarín that Valenzuela will finally take up his Senate seat, which he swore into on December 8 of the previous year. His election came despite the challenge from the Peronist Party (PJ) in the densely populated electoral section that includes municipalities from the northern and western suburbs of Buenos Aires. His experience as former mayor and his expected contributions as a senator will be closely watched by political observers, especially in the context of Seguridad and Migration policies within the current administration.

The cessation of the new Migration Agency's creation reflects ongoing tensions within the ruling coalition, as the internal disputes suggest a lack of unity in handling immigration issues that are becoming increasingly pertinent in Argentina. Valenzuela's return to the provincial Senate marks a significant move for him personally, as he navigates the shifting political landscape and seeks to assert his role in legislative discussions on critical local matters, including security and migration.
