The Public Function Secretary described the budget's irregularities as "monumental and immoral".
Mexico's authorities reported that irregularities in projects worth US$30.2 billion were detected during President Enrique Peña Nieto's administration (2012-2018).
The Public Function Secretary Irma Sandoval said that irregularities were identified in 2019 projects, which generated more than 10,000 observations associated with that amount of embezzled money.
She described the irregularities found during the budget's execution as "monumental and immoral".
Her report adds that the amount executed with alleged irregularities is higher than the federal budget for the education and health sectors as a whole.
Mexican authorities explained that the Civil Service carried out nearly 3,400 inspections in 2019. Over 2,500 of them were audits that generated more than 10,000 observations.
Imágenes de la detención en España de Emilio #Lozoya— Arturo Luna Silva (@ALunaSilva) February 12, 2020
¿Algún día veremos así al loquito de Fox, al inútil de Calderón o al corrupto de Peña Nieto, o México seguirá siendo el país donde a sus expresidentes no se les toca ni con pétalo de una rosa? pic.twitter.com/zQMuXoNkzk
"Images of Emilio Lozoya's detention in Spain. Will we ever see the fool of Fox, the useless of Calderon' or the corrupt of Peña Nieto like that? Or will Mexico remain the country where not even a rose petal touches its former presidents?
Sandoval also mentioned emblematic cases such as actions against the former director of Pemex Fertilizantes, Edgar Torres, for irregularities in the purchase of the Fertinal group, in which he embezzled more than US$210 million from the state.
On Wednesday, Mexican authorities confirmed the capture of Petroleos Mexicanos (Pemex) former director Emilio Lozoya in the city of Malaga, Spain.
He is wanted by President Andres Manuel Lopez Obrador (AMLO) administration to be prosecuted for participating in organized crime, bribery, and operations with resources of illicit origin in the Odebrecht case.
This marked the first big case against former President Peña Nieto's inner circle. True to his campaign promise, President AMLO has worked to root out corruption in his country's public sector.
