Yeah, I heard that one too. It's hard to figure out what it was he did - was it stupid stuff like calling someone "Blondie", or was it real, predatory behavior?
@Sanguine I saw a few moments of Margaret Hoover on CNN this morning, talking with Alysyn Camerota, who used to work at Fox. Hoover said that O'Reilly never sexually harassed her, but that she always felt like she was walking a tightrope when she appeared on his show. He regularly commented on her clothing, her makeup, the length of her skirt, and she said it was clear that the assumption was he had the authority to do that kind of thing, and women were expected to pay attention to his instructions.
Camerota said that sexual harassment by Ailes was the reason she left, and she talked about the morale among women employees at Fox (it was, and still is, lousy). They all know that they don't have the option of speaking up if they want to keep their jobs. Hopefully that might be changing now.
