Mexico's president slams U.S. "spying" after 28 Sinaloa cartel members charged, including sons of "El Chapo"

Mexico's president lashed out Monday at what he called U.S. "spying" and "interference" in Mexico, days after U.S. prosecutors announced charges against 28 members of the Sinaloa cartel for smuggling massive amounts of fentanyl into the United States. The three sons of former drug lord Joaquín "El Chapo" Guzmán  — known as the "Chapitos" —  were among those charged.

President Andrés Manuel López Obrador suggested Monday that the case had been built on information gathered by U.S. agents in Mexico, and said "foreign agents cannot be in Mexico."

He called the Sinaloa investigation "abusive, arrogant interference that should not be accepted under any circumstances."
