Trump accused almost every TV channel in the United States of showing fake news. He refused to accept real images of small crowds at his inauguration. His claims have no basis in reality.
Trump is the man who has disseminated fake news. He spread the dangerous fallacy that hundreds of Muslims gathered in New York celebrated the fall of the World Trade Towers. There is no evidence that this occurred. This stoked detestation of the already beleagured Muslim community in the United States.
