In early 2018, disinformation site YourNewsWire revived the conspiracy theory, publishing a false story that “Cuba claims Justin Trudeau is Fidel Castro’s son.” The conspiracy theory was reportedly revived online after YourNewsWire — which spread far-right conspiracy theories including Pizzagate and QAnon — published an article titled “Cuba Claims Justin Trudeau Is Fidel Castro’s Son.” According to Vice, the article “outlines a tale that a suicide note which was found next to Fidel Castro’s son in which he states that Castro's son complained that his father repeatedly and unfairly compared him to Justin Trudeau and then states, ‘but what was I to do? I am Cuban. My brother is Canadian.’” The article and its claims were then reportedly “amplified by 4Chan trolls, far-right blogs, and the worst people on Twitter who all took this as fact and worked to further the theory.” [Vice, 2/20/18; Media Matters, 2/1/18; Poynter, 7/20/18]
