As someone stated in the video comments, he's probably drawing more attention to his actions from people --including supporters-- who may not have been aware of the scandal. He wants to focus on the stuff he can easily refute or treat as "bullying," but those people will eventually stumble onto the stuff he admitted to everyone. I can't stress enough how damaging the stuff he admitted to is. Or how bad it looks that his version of damage control is to claim that cheating on his wife with hookers is his dick's fault, and besides... it's not like he killed anyone.
Maybe he realizes how bad that video makes him look. Probably not, because instead of pretending none of it happened and trying to crawl away in shame, he keeps pretending he occupies a high moral ground. In the end, it just makes his eventual fall that much farther.
