On January 9, 2012, del Castillo publicly posted an essay on Twitter (using Twextra) discussing social issues in Mexico that included controversial statements directed towards Joaquín Guzmán Loera, the infamous head of the Sinaloa Cartel. The essay included requests to Mr. Guzman to "deal with love, with good things" and to "to traffic in love." The most controversial portion of the essay stated: "Today I believe more in Chapo Guzmán in the government that hides painful truths from me, that hides the cure for cancer, AIDS, etc., for their own benefit and wealth."
