The former governor of Baja California Sur, Francisco J. Múgica (by then estranged from the PRI) made some statements during the campaign accusing Ruiz Cortines of having collaborated with the Americans during the 1914 US occupation of Veracruz. Ruiz Cortines denied the accusations and claimed that at the time he was in Mexico City in service of the Revolution under the command of Alfredo Robles Domínguez and Heriberto Jara Corona. Later in the campaign, during a visit to Veracruz on 7 June, the Municipality of Xalapa honoured him with a parchment denying the accusations and naming him a "Patriot and Illustrious Son of Veracruz".
