The source for your article seems to be a website devoted to political conspiracy theories, my story on Trump came from the Huffington post, now the Huffington post is left of center, but not far enough left to confuse an unsubstantiated story with a real event, obviously they had contact with the girls lawyers for the story, I don't think they would just make up the whole thing, that doesn't mean the accuser is truthful, it just means there most likely is an accuser, a court case, and lawyers representing her.
