White House Chief of Staff 'Appalled' by 'El Chapo' Guzman's Comments in Interview With Sean Penn

A top White House official called his comments to Sean Penn "appalling."

McDonough was responding to the interview posted Saturday by Rolling Stone, in which Penn revealed he was in contact with Guzman following his escape from a Mexican prison last summer.

While Mexican government sources told ABC News Penn and Kate del Castillo, the actress who Penn says helped arrange the meeting, are under investigation for their "interview" with Guzman, McDonough did not mention the potential for an investigation by federal authorities.

“We'll let somebody else sort out what Sean Penn did and didn't do,” he said. “'El Chapo's' where he should be."
