NEW YORK | Sean Penn says his article on Mexican drug lord Joaquin “El Chapo” Guzman “failed” in its mission.

Speaking to “60 Minutes,” the actor said his intention in tracking down the escaped drug kingpin and writing about him for “Rolling Stone” was to shed new light on the U.S. government’s policy in the War on Drugs.

But the public’s attention has been focused instead on how Penn found and met with him last October when Mexican officials couldn’t. Guzman was re-captured only last week after six months on the run.

Penn said the Mexican government was “clearly very humiliated.”

He said he had hoped that his article would begin start a conversation about drug policy.

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

“60 Minutes” airs on CBS Sunday.
