A Conversation with Mary L. Trump

Mary L. Trump's new bestselling memoir is called, “Too Much and Never Enough: How My Family Created the World's Most Dangerous Man.” She is President Trump’s only niece and a trained clinical psychologist, and in the book describes an ambitious and challenging family environment. There were efforts to block the publishing of the book and President Trump has called her writings “untruthful.” Trump joins Washington Post national political reporter Robert Costa for a one-on-one conversation to discuss her book and what brought her to write it at this time.
