Trump neither smokes , drinks because of his alcoholic brother, Fred who died at 42 in 1981. Mary was his daughter. She and her brother have been in a feud with the rest of the Trump family since 2000 when they sued for part of their grandfather's estate. Fred, Jr. was married to an airline stewardess and divorced. The mother's name is not even mentioned so I'm surmising that Mary and her brother were brought up by their mother and never were much included in the Trump family. (There's the sour grapes theory.) On top of that, Mary is a Democrat and was a staunch Hillary supporter. I would read the excerpts and save your money. It would seem to be pretty predictable saga and any salient points will be in the media.
