Well we don't know if she is totally innocent yet, todays proceedings will tell us. But again Innocent until proven guilty.
There's a lot of people calling for her resignation simply because she was in a relationship with someone. She legitimately may not have been aware of her ex partners business dealings.
If she has done nothing wrong this shouldn't cost her. This includes not reporting him if she knew something was up (how to prove this may be a little tricky however) If she has then i will change my opinion. Until then we need to let the ICAC do its job
