Comando Jaramillista Morelense 23 de Mayo (CJM-23) is a small group based in Morelos, Mexico that opposes the corruption and economic policies of the Mexican government. The group's name is derived from a local revolutionary hero, Ruben Jaramillo, who rallied the peasantry in southern Mexico around a socialist platform in the 1940s and 1950s. Jaramillo, who fought as a teenager with the Zapatista movement during the Mexican revolution, and his family were killed by government forces on May 23, 1962. <p><br />The group first appeared on May 23, 2004 when members claimed responsibility for the bombing of three foreign-owned bank branches in Jiutepec, a city in the state of Morelos. As the explosions occurred at midnight on a Sunday, only material damage was sustained in the largely symbolic attack. In leaflets found at the bombings sites, CJN-23 criticized Mexican President Vicente Fox and Sergio Estrada, the governor of Morelos, protesting Fox's neo-liberal economic policies and Estrada's corruption and alleged ties to narcotics.  In June 2004, CJN-23 issued a statement, voicing their support for the <a href="?id=4418"> Ejercito Zapatista de Liberacion Nacional (EZLN)</a>. Based on the CJN-23's statements, its choice of targets, and the symbolism associated with Ruben Jaramillo, the group is believed to espouse an anti-imperialist, socialist-oriented ideology that strives to purge corruption from the Mexican government and improve the lives of Mexico's lower classes.  <p><br />On September 1, 2004, the group made its first armed appearance on a rural road outside of Mexico City, discharging firearms and handing out anti-government propaganda. The group also claimed responsibility for two simultaneous bombings in Cuernavaca on the first of September and another bomb, which failed to detonate, outside of a television station ten days later. However, it remains unclear if CJN-23 was actually responsible for the September bombings. Statements issued following the bombings criticized President Fox, Mexico's two largest political parties -- Fox's Partido Accion Nacional (PAN) and the Partido Revolucionario Institucional (PRI) --  and neo-liberalism.  <br />
