Why are Kim Min-seok and Park Sun-won silent regarding the Shincheonji Jung Chung-rae issue???

They said they would reveal it after the leadership election, so why are they still keeping their mouths shut?
Is it because there is something to reveal, but they don't want to cause a stir in the party right now??
Or is there nothing, and they just want to blabber whenever they feel like it?
Why is even Jung Chung-rae staying silent on this matter??
Is it because it's the truth???
Or because they hate making the party noisy???
Since when did you become such a scholar???
