Actor Sean Penn is breaking his silence about his trip to Mexico to meet notorious drug lord Joaquin "El Chapo" Guzman. In an interview for this Sunday's "60 Minutes," Penn spoke to "CBS This Morning" co-host Charlie Rose Thursday night in Santa Monica to talk about his seven hours with Guzman. "There is this myth about the visit that we made, my colleagues and I with El Chapo, that it was -- as the Attorney General of Mexico is quoted -- 'essential' to his capture," Penn said. "We had met with him many weeks earlier...on October 2nd, in a place nowhere near where he was captured." Penn also told Rose he thinks he was able to get access to El Chapo because he's not a traditional journalist, and he doesn't think any traditional journalist would have had success.
