Actor Sean Penn's expressing no regrets about his clandestine visit to interview Mexican drug lord Joaquin "El Chapo" Guzman.
In a brief email exchange with The Associated Press, Penn was asked about images published in Mexican news media Monday that appeared to show officials watching him and actress Kate Del Castillo ahead of their October visit with Guzman.
"I've got nothin' to hide," he wrote.
Guzman was captured last Friday, more than three months after Penn's Oct. 2 meeting with him in central Mexico and six months after escaping from prison.
Penn did not respond directly to questions on whether it was appropriate for him to submit his story to Guzman for approval in advance of publication, or whether he took adequate information and operational security measures to protect his source.
