MEXICO CITY — The mother of convicted drug kingpin Joaquín “El Chapo” Guzmán said Saturday that the U.S. Embassy in Mexico City granted her a visa to visit her son in prison.

Consuelo Loera said that she and two daughters were both approved Saturday for visas to travel to the United States.

“Thank God, the U.S. Embassy gave me the permission,” she said. Loera said she hasn’t seen her son in more than four years. If she could bring him anything, she said, it would be his favorite Mexican food dish: enchiladas.

Mexican President Andrés Manuel López Obrador lobbied for the visa to be issued after receiving a letter in February from Loera asking for assistance. In the letter, Loera described herself as “suffering and desperate” to see her son. The president said he intervened out of empathy for the mother.
