Republican U.S. presidential candidate Donald Trump parroted a baseless conspiracy theory about Prime Minister Justin Trudeau possibly being the son of former Cuban president Fidel Castro on Monday.

In the interview with Adin Ross, a controversial 24-year-old internet influencer and livestreamer, Trump also discussed his relationship with other world leaders and public figures, including a number of Democrats, Tesla CEO Elon Musk, who he called a “genius” and “a very good person,” and rapper Kanye West, who he said has a “good heart,” but is “very complicated” and “can get himself into trouble.”
