A chaotic scene unfolded during a public session of Mexico’s Senate as two senior officials clashed physically, sparking widespread attention. Video footage circulating on social media captures the incident, which involved Senate President Gerardo Fernández Noroña of the ruling Morena party and Alejandro Moreno Cárdenas, leader of the Institutional Revolutionary Party (PRI).

The confrontation began after PRI members sought to speak during the session but were repeatedly denied by Noroña, who presided over the chamber. As Mexico’s national anthem concluded, Moreno approached the podium and confronted Noroña, leading to a series of shoves and ultimately a punch. The altercation escalated when a staffer attempted to intervene and was pushed to the ground. Noroña, reportedly frustrated, exited the chamber after further physical exchanges and heated verbal arguments.

The clash occurred amid tensions over procedural disputes, with PRI members alleging that their requests for floor time were systematically ignored. Moreno, who has led the PRI since 2019, faces challenges in revitalizing a party that once dominated Mexican politics but now holds limited influence. Noroña, a leftist politician aligned with President Andrés Manuel López Obrador’s Morena movement, assumed his role as Senate president following the 2024 elections, which expanded Morena’s congressional majority.

The incident highlights deepening political divisions within Mexico’s legislative body, where ideological clashes often spill into public view.
