Marx Arriaga Navarro, former head of the Directorate of Educational Materials (DGME), rejected the accusations published by the newspaper El Universal regarding a supposed complaint filed against him with the Internal Control Body (OIC) of the Ministry of Public Education (SEP). In an interview with Aristegui en Vivo, Arriaga stated that he has not received any official notification about a complaint against him. He emphasized that he does not know the content of the document, while pointing out that the institution has mechanisms to determine responsibilities if evidence is presented. Regarding the version that indicates Sady Arturo Loaiza Escalona, director of Educational Materials Development and Innovation, would have requested deposits with his consent, Arriaga affirmed that the complaint in question was formalized from the very directorate he headed. "That complaint I filed myself, as a public official, and it is being investigated by the internal control body," he declared. He noted that he has been a teacher since 2002, a member of the National System of Researchers since 2010, and holds a bachelor's, master's, and doctorate degrees, in addition to national and international recognitions. Arriaga stated that his stay in office was symbolic in nature to make visible what, in his opinion, are bureaucratic practices that affect the teaching profession. He also stressed that he has never improperly used public resources. Specifically, he denied the accusations that during his administration, funds were allocated to certain private publishers. He added that he will wait for an official notification to hand over his position. Regarding the statements by President Claudia Sheinbaum about the supposed lack of content about women in history, Arriaga considered this information to be incorrect. He emphasized that the theme is already included in the textbooks and that there is no document that formally instructs to incorporate this content. He also stated that behind the attempts to modify the materials lies the intention to reverse the educational model and reopen spaces to private publishers and business actors.
