VIDEO : Sean Penn Brushes Off El Chapo Criticism

MEXICO CITY ? Actor Sean Penn dismissed criticism of his interview with Mexican drug lord Joaquin "El Chapo" Guzman in a supposedly secret meeting that authorities say helped them track down the world's most-wanted trafficker. "I've got nothin' to hide," Penn told The Associated Press after images published Monday indicated he was under surveillance when he met with the Mexican actress who led him to Guzman ? and the pair was apparently followed and photographed as they set out for the meeting with the drug lord at a hideout in rural Mexico in October.
