Trump's behaviour shaped by his 'sociopath' father: Niece in new book

Donald Trump's behaviour was shaped by his "high-functioning sociopath" father during childhood, according to a book written by the US President's niece Mary Trump. He embraced cheating "as a way of life", wrote Mary, a clinical psychologist. She also alleged that Trump paid someone else to take his college admission test, helping him get into the Wharton business school.
