Speakers said that the prosecution should not investigate only those who would bring less burden to the "president" but make a thoroughgoing investigation into all those involved in the scandal as exposed by Song Wan Jong.

Eight persons involved in the scandal are telling lies and core witnesses are appeased or handled without any trace left, they charged.

The prosecution should investigate not only Ri Wan Gu, former "prime minister", and Hong Jun Phyo, a lawmaker from the "Saenuri Party" who is governor of the South Kyongsang Province, but also six others.
