Luis Donaldo Colosio Riojas, a senator for Mexico's Movimiento Ciudadano party, said he has been Sonoran all his life and that his academic records and birth certificate identify him as a native of Magdalena de Kino, Sonora, in response to questions from Morena national leader Ariadna Montiel about his origin and his tenure as mayor of Monterrey.[^1]

Colosio Riojas questioned Morena regarding a birth certificate published in Mexico City that he claimed was unknown to him.[^2] He stated that Morena is nervous because they see a risk and are trying to disqualify him by publishing a document he does not recognize.[^3]

The PRI State of Mexico indicated in a press release that Movimiento Ciudadano does not build a real government alternative for Mexican families and insists on dividing those competing against Morena.[^4]
