Dr. Mary Trump is niece of The Donald. For a long time, her closest friends had no idea. She was a super private citizen. But then, she went mega-public to talk about her uncle’s cruelty during his presidency. She was the source for a Pulitzer-prize winning investigation in The New York Times into the Trump family’s finances. And her tell-all family memoir sold more copies in one week than Donald Trump’s Art of The Deal sold in its lifetime. It made bestseller history. Mary Trump isn’t used to talking about herself. But THAT is the point of our conversation. Mary on Mary. She’s self-effacing, she defected from her family. But why did she do it? Well, it comes down to privilege. She’s always known she has it. Then, the moment came when she knew she had to use it. And Mary fans: did you know she’s a bird person?
