“I have a terrible regret,” Penn said in the interview recorded on Thursday in California.

“Let me be clear. My article has failed,” said Penn.

Rolling Stone published Penn’s article on Saturday, a day after Guzman’s recapture.

The piece cited the drug lord boasting about smuggling drugs into the United States, and about laundering ill-gotten gains.

Guzman’s lawyer on Wednesday accused Penn of lying, and said he should be called to give evidence.

“W’s the proof? W’s the audio?”.

Neither Penn’s publicist nor Rolling Stone have commented on Badillo’s claims.

A government spokesman said on Tuesday that Mexico was not directly investigating Penn nor his companion, actress Kate del Castillo, but rather the circumstances around the meeting.
