In July 2017, Fox was an international observer to the unofficial Venezuelan referendum held by the opposition.

Fox eventually apologized for the remark, while also asking for Trump to apologize for his remarks about Mexicans and inviting Trump to visit Mexico. 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
