 In 2016 a group of Venezuelans asked the National Assembly to investigate whether Nicolás Maduro was Colombian in an open letter addressed to the National Assembly president Henry Ramos Allup that justified the request by the "reasonable doubts there are around the true origins of Maduro, because, to date, he has refused to show his birth certificate".The 62 petitioners, including former ambassador Diego Arria, businessman Marcel Granier and opposition former military, assuring that according to the Colombian constitution Maduro is "Colombian by birth" for being "the son of a Colombian mother and for having resided" in the neighboring country "during his childhood".The same year several former members of the Electoral Council sent an open letter to Tibisay Lucena requesting to "exhibit publicly, in a printed media of national circulation the documents that certify the strict compliance with Articles 41 and 227 of the Constitution of the Bolivarian Republic of Venezuela, that is to say, the birth certificate and the Certificate of Venezuelan Nationality by Birth of Nicolás Maduro Moros in order to verify if he is Venezuelan by birth and without another nationality".
