Deputies of the Democratic Revolution Party (PRD) requested that Mexico's National Electoral Institute (INE) investigates if the Green Party (PVEM) offered money to artists and personalities to promote voting for it.
Among those who sent such messages on social networks were Miguel Herrera, Inés Sainz, Aleks Syntek, Julio César Chávez, Jan Cárdenas and Gloria Trevi, among others.
The proposal was endorsed by PRD deputies Miguel Alonso Raya, Antonio León Mendívil, Lizbeth Rosas Montero, Gloria Bautista Cuevas, Amalia García Medina, Fernando Belauzarán, Lourdes Amaya Reyes and Graciela Saldaña Fraire, who want the party to be fined.
The Mexican Soccer Federation is also investigating Herrera and two players over the politically tinged tweets sent the day of the elections. On Monday the federation said that it will evaluate whether Herrera, Oribe Peralta and Marco Fabián violated its code of ethics, which calls for "maintaining a neutral position on matters of a religious or political nature."
