Let’s start with her supposed phone call to Jackie Kennedy where she is to have told her about the affair and that she was going to become first lady. Marilyn wasn’t the kind of spiteful person that would do such things. She also wanted to be an actress, not the First Lady of the United States. She was a private person and didn’t have any desire to have people poking around her private life. And why would she set out to destroy her career that she had worked so hard to build by announcing to the world she was having an affair with the President.
Jackie Kennedy is also said to have detested After the Fall (based on Marilyn) written by Arthur Miller. Why would she bother to care enough about someone who was allegedly her husband’s mistress?
According to Sarah Bradford, in her biography America’s Queen: The Life of Jacqueline Kennedy Onassis, “Jackie, who had admired Arthur Miller enough to seat him at her table at the Malraux dinner, turned on him for his betrayal of Marilyn in his play After the Fall, which opened in New York on January 23, 1964. For [Jackie Kennedy] loyalty was the ultimate test of character, and in portraying Marilyn as a self-destructive slut whom he had abandoned for her own good, Miller had dismally failed it.
