I don't think Trump is a good guy, but I also think the story was hilariously bad. In a nutshell this is the story:
E. Jean was walking out of a department store as Trump was walking in. He noticed her and said "hey, you're that really famous and beautiful writer." She looked at him and noticed how much taller and more handsome he was in person. [not kidding...that is in her story] He said "you give such amazing advice in your newspaper columns that I must have your advice on what to buy for Christmas presents". She giggled and went with him back into the department store. Small talk, small talk, small talk. This man she hated was not to be denied and put her on a counter in the middle of the department store to make mad passionate sex.
In the Christmas shopping season in a department store in Manhattan, no one saw it, no staff saw it, no cameras recorded it, she didn't tell anyone about it until years later, and there is no evidence that Trump had any clue who this columnist even was before she told her sex story involving him.
