>> alejandro, i have a short amount of time here, the u.s. law enforcement officials knew that sean penn -- knew of his interactions with kate del castillo and the connection to el chapo before they travelled to see him in october. what do they know? >> well, we don't know for sure. but certainly, this was no secret for intelligence agencies in both countries. there have been -- i mean, in the mexican press has published pictures of sean penn and kate del castillo in airports traveling to see el chapo. they were under surveillance far before the actually encounter. this is quite surprising for a man known for his paranoia for that has been on the run for so long that should be an expert at really taking precautions to lower his guard this way. i think that's quite remarkable.
