I've just finished Mary Trump's book, Too Much and Never Enough...
It was sad to read how dysfunctional the family was. It read more like a biography of Mary's life within the family, only in the final two chapters did she discuss Trump's behavior in the White House.
But of course she did not say anything most of us already knew, he's delusional about himself, and a danger to America. The sooner he is voted out the better.
