Actor Sean Penn is under investigation for a Rolling Stone magazine interview with drug kingpin Joaquin Guzman, ABC News reported, citing unidentified people in the Mexican government.
Kate del Castillo, the Mexican actress whom Penn says helped arrange the meeting, is also being investigated, the report says.
The U.S. Department of Justice declined to comment on the Rolling Stone story and whether the interview led to Guzman's recapture by Mexican authorities on Friday, ABC says.
Penn spoke with Guzman, known as "El Chapo," for seven hours in October while he was on the run from the authorities, and had follow-up interviews by phone and video, the Rolling Stone said.
