In the same interview, De Niro also said he considers Trump a fascist and a white supremacist. 

De Niro has railed against the president in countless interviews and public appearances, saying onstage at last year’s Tony Awards, “F--- Trump!” He has also referred to Trump as a “jerkoff in chief” and a “f---ing idiot.”

Trump has hit back at De Niro in the past, nicknaming him “Punchy” and dubbing him a “very low IQ individual” in a tweet last year.
