A new book has revealed that Melania Trump used her position as the US First Lady to renegotiate her pre-nuptial agreement with husband, President Donald Trump before she moved into the White House after he was elected to office. "The Art of Her Deal: The Untold Story of Melania Trump" by Washington Post reporter Mary Jordan, "draws an unprecedented portrait of the First Lady" based on interviews with more than 100 people in five countries. Melania didn't move into 1600 Pennsylvania Avenue until June 2017 - six months after the President took the oath of office. And she used that time to renegotiate her prenuptial agreement, claimed the book.
