Despite his apology, Fox continued to criticize Trump to the international media and troll Trump on Twitter, stating, "I'm committed to be Donald Trump's shadow until he is done with politics." When Trump visited Mexico on 31 August 2016 upon President Enrique Peña Nieto's invitation, Fox slammed the visit, calling it a "desperate move" on the part of Peña Nieto and stating, "He is not welcome in Mexico. We don't like him. We don't want him. We reject his visit." Trump responded by pointing out Fox's previous invitation, to which Fox clarified that he invited Trump to Mexico on the condition that he used the visit to apologize to the Mexican people. He directly addressed the American people the next day on CNN, where he described Trump as a "false prophet" who is "absolutely crazy" and warned that they need to "wake up" and realize the harm that Trump's immigration and economic policies would inflict on the United States.
