Thomson Reuters MEXICO CITY (Reuters) - Pope Francis launched a broadside against endemic corruption on Saturday on his first visit to Mexico as pontiff, calling on President Enrique Pena Nieto and his government to combat it. Corruption is deeply ingrained in Mexico, and Pena Nieto, his wife and finance minister have all been embroiled in conflict of interest scandals involving homes purchased from government contractors. The pope also exhorted Mexico's bishops to take a more active stand against the drug trade, which he said "devours like a metastasis." He told them to make it clear to drug dealers that they could not consider themselves good Catholics if their hands were "drenched in blood, but pockets filled with sordid money and their consciences deadened." Drug-trafficking gangs have infiltrated police forces across the country and more than 100,000 people have been killed in drug violence over the last decade.
