O'Reilly is a blowhard and totally in love with himself, but he's not stupid. I'm not buying it. At the very least, there is a lot more to the story.
I'm reading the filing at SmokingGun right now. As of Page 11, Macklis has nothing on O'Reilly that rises to the level of harassment. He treated her well but apparently trusted her too much by discussing sexual topics with her in a way that friends discuss sex, forgetting, much to his eventual regret I'm sure, that she was an employee. That relationship -- employer to employee -- is so laden with legal baggage in today's world that no sane boss can afford to get personal with an underling.
In any case, though the claim of actual sexual harassment looks weak, O'Reilly is toast as a serious pundit. Some of the slimy stuff in these papers he will never be able to live down. In fact, his lowlife comments to Macklis tend to confirm what I have always thought about him -- he's a mental midget blowhard egotist.
