One of Donald Trump's nephews has described his uncle as "atomic crazy" in a book about his family. Fred C Trump III also says the former president used racial slurs and told him disabled people, like his son, should be left to die. The Trump family have responded to the publication, saying that Fred is "cashing in" on the former president. Report by Covellm.
