Washington: Deep in the Mexican jungle US actor Sean Penn met with drug lord Joaquin "El Chapo" Guzman in October, gathering material for an article that was published Saturday, after the capo's arrest.
The Mexican government, which says it knew of the meeting, wants to question Penn while the White House has remained mostly mum and analysts say Penn has not likely done anything illegal.
Below is a summary of what we know so far:
Actor meets drug lord
According to the article, written by Penn and published in Rolling Stone magazine, the Hollywood star landed October 2 in Mexico, where he and Mexican actress Kate del Castillo were ushered to meet Guzman in the jungle.
To land the interview, Penn says, he rode "on the coattails of El Chapo's faith in Kate," the Mexican soap opera star who once played a drug baron and had caught Guzman's attention.
During "a seven-hour sit-down," carried out in part over sips of tequila, Penn said he held off on hard-hitting questions, expecting to interview the world's most wanted drug baron in full eight days later.
By that time, however, the situation had changed, Guzman was no longer available, and the drug lord would go on to answer Penn's questions via video recordings without the Hollywood star present.
Capo captured
The Rolling Stone article came out one day after authorities arrested Guzman in a military raid early Friday that left five suspects dead in Los Mochis, a coastal city in his native northwestern state of Sinaloa.
Authorities were able to locate Guzman, in part, because he wanted to make a biographical film, Attorney General Arely Gomez said before the article's release, adding that the drug baron had "established contact with actresses and producers."
The Sinaloa cartel kingpin was flown to the Altiplano maximum-security prison, some 55 miles (90 kilometers) west of the capital, from which he had escaped in July.
No stranger to escaping
After just 17 months at Altiplano, Guzman slipped through a hole in his cell's shower on July 11, climbed on a motorcycle mounted on rails, and traveled 1.5 kilometers (one mile) through a tunnel to freedom.
Guzman had been captured on February 22, 2014 in the Sinaloa resort of Mazatlan after 13 years on the lam.
He escaped a first time in 2001 from another prison by hiding in a laundry cart having spent eight years in jail following his 1993 capture in Guatemala
Extradite Guzman, question Penn
A Mexican federal official told AFP Saturday that authorities had known about Penn's meeting with Guzman before his capture and that it was a part of the investigation that helped lead to the drug lord's apprehension.
On Sunday a federal official told AFP that the attorney general's office wanted to talk with Penn and del Castillo about their secretive meeting.
"It's to determine responsibilities," the official said on condition of anonymity, declining to provide more details.
Meanwhile prosecutors announced Saturday that they would seek Guzman's extradition to the United States, a reversal from President Enrique Pena Nieto's refusal to send him across the border.
The attorney general's office said it received two US extradition requests last year on a slew of charges, including drug trafficking and murder, and that it later obtained arrest warrants to ship him across the border.
'Lot of interesting questions'
The White House, which has denounced comments made by Guzman himself during the interview, said of Mexico's requests to question Penn: "It poses a lot of interesting questions for him and others involved in this so-called interview. We'll see what happens."
Leading media lawyer Floyd Abrams told AFP Sunday that the interview will not likely put Penn in any legal jeopardy as it "doesn't violate any law."
