Speaking at a virtual fundraiser Thursday, when asked how far she believes her uncle would be willing to go to remain in the White House, she replied, "farther than you can possibly imagine," reported the Huffington Post. Mary Trump has emerged as a vocal critic of her uncle, claiming that a scarred childhood has left him with a series of pathological personality traits.
