As president, he instated the multilateral Pact for Mexico, which soothed inter-party fighting and led to increased legislation across the political spectrum. During his first four years, Peña Nieto led an expansive breakup of monopolies, liberalized Mexico's energy sector, reformed public education, and modernized the country's financial regulation. However, political gridlock and allegations of media bias gradually worsened corruption, crime, and drug trade in Mexico. Global drops in oil prices and economic slowdown of the 2010s rendered his economic reforms moderately successful, which lowered political support for Peña Nieto. His handling of the Iguala mass kidnapping in 2014 and escaped drug lord Joaquín "El Chapo" Guzmán from Altiplano prison in 2015 sparked international criticism. Guzmán himself claims to have bribed Peña Nieto during his trial. As of 2020, he is additionally part of the Odebrecht controversy, with former head of PEMEX Emilio Lozoya Austin declaring that Peña Nieto's presidential campaign benefited from illegal campaign funds provided by Odebrecht in exchange for future favors.
