A closing session of Mexico’s Commission Permanente erupted into violence on 27 August when opposition leader Alejandro “Alito” Moreno, head of the Institutional Revolutionary Party, stormed the rostrum and grabbed Senate president Gerardo Fernández Noroña after being denied the floor. Video from the chamber shows Moreno shoving and striking the Morena senator as lawmakers finished singing the national anthem, while a photographer, Emiliano González, was knocked to the ground and injured amid the scuffle. Fernández Noroña told reporters that Moreno threatened him and that other PRI legislators joined the assault. He said he will file criminal complaints for assault and property damage and ask the Fiscalía General de la República to request the desafuero—lifting of parliamentary immunity—of Moreno and at least three fellow PRI lawmakers. An emergency session of the Commission is set for Friday to consider additional disciplinary measures. Moreno acknowledged the confrontation but accused Fernández Noroña of throwing the first shove and claimed the clash stemmed from “seven years of insults, threats and political persecution.” The PRI chief already faces separate corruption allegations dating to his tenure as governor of Campeche (2015–19). President Claudia Sheinbaum condemned the fight as an “authoritarian” act that exposed the opposition’s true character. The altercation followed a heated debate in which ruling-party senators accused PRI and PAN lawmakers of backing U.S. military intervention against drug cartels—an allegation the opposition denies.
