Hey, do we know who called it quits or why? Did he leave because he wanted to, or because he felt it was simply time to? Or did she "fire" him? I know there were rumors since the trial that they weren't getting along, or not even rumors as much as just pure speculation based on how they behaved towards each other.
Also, and PLEASE don't fry me for saying this, but I think that she was a HUGE boost to his career. Personally, if I were in his shoes I would never want to be associated with her at all, but, there are people out there requiring a defender who would see him as being very successful. JMO.
