Sean Penn under investigation for secretly interviewing "El Chapo"

Sean Penn is now under investigation for the interview with fugitive Mexican drug lord Joaquín Guzman, known as ''El Chapo,'' ABC News reported Saturday night citing Mexican official.

Since the 55-year-old Oscar-winning actor had been in contact with Guzman for several months, authorities are presumably interested to find out why the actor did not earlier share any information on the wanted man

Penn's interview helped lead authorities to Guzman, who was captured and returned to prison Friday.
