This is actually a pro-Trump film. From the description:
Donald Trump dominated the 2016 Presidential race with a master plan of political incorrectness, using The Art of the Insult to brand political opponents and bash the media all the way to the White House. In this film, Trump emerges as a marketing genius and performance artist who, despite being a Manhattan billionaire, captured the hearts of middle America. Critics are calling Trump: The Art of the Insult “the most entertaining political film ever!”
The film has been endorsed by birter kingpin Jerome Corsi and the usual clown car cavalcade of crackpots.
Director Joel Gilbert also made Dreams Of My Real Father, which claims that Barack Obama’s father was actually a Communist Party USA organizer.
