Nicolás Maduro's birthplace and nationality have been questioned several times, with some placing doubt that he could hold the office of the presidency, given that Article 227 of the Venezuelan constitution states that "To be chosen as president of the Republic it is required to be Venezuelan by birth, not having another nationality, being over thirty years old, of a secular state and not being in any state or being in another firm position and fulfilling the other requirements in this Constitution. After his triumph in the 2013 presidential elections, opposition deputies warned that they would investigate the double nationality of Maduro.
