Mexico has agreed to send Joaquin El Chapo Guzman to the United States for prosecution. Guzman is leader of the Sinaloa crime group. He faces numerous charges in the U.S., including drug trafficking, kidnapping and murder. The Mexican government rejected U.S. requests earlier to turn over Guzman. It changed its position after he escaped a Mexican prison last July for the third time. Federal police captured him Friday after a gun battle. The legal process to send Guzman to the United States could take months. Guzman's lawyers said they will oppose the extradition effort. The prisoner could be sent to one of several U.S. cities for trial, including New York or Chicago. Mexican officials want to question American actor Sean Penn in connection with the Guzman escape. Penn met with the crime group leader in October to gather information for a story for an American magazine, Rolling Stone. The magazine’s web site posted the interview Saturday. Mexican officials also want to question Mexican actress Kate del Castillo. She reportedly set up the meeting between Penn and Guzman.
