Na Kyung-won and Han Dong-hoon are targeting "the act of being loud."

Na Kyung-won, a member of the People's Power, criticized Han Dong-hoon, who ordered an inspection into the alleged "attack owner" of former President Kim Dae-nam's office, as an act of making noise.

Rep. Na appeared on CBS radio and said, "You may be able to conduct a fact-finding investigation, but all of the representative's aides should come forward and raise the issue."

He then pointed out that close lawmakers told him at first that the president's office seemed to be behind him, but he seemed to be the only way to be deceived by the left-wing camp.

Rep. Na acknowledged that former administrator Kim served as his special advisor in the face of the national convention, but drew the line that he was not in a position to discuss any issues with him.
