Officials say drug kingpin Joaquin "El Chapo" Guzman has been formally charged with violations of Mexico's drug-trafficking laws, starting a legal process that makes swift extradition to the U.S. unlikely.
Guzman was charged with cocaine trafficking Sunday inside a maximum-security prison, Mexico's Federal Judicial Council announced. A judge has until Tuesday to decide whether to bring Guzman to trial here but a Mexican federal official said that Guzman faces a series of other charges in Mexico.
Rulings on all the charges will significantly delay any extradition decision, the official told The Associated Press on condition of anonymity.
U.S. officials have been pushing for Guzman's swift extradition. He faces charges in at least seven U.S. jurisdictions.
