On December 20, Democratic Party leader Jeong Cheong-rae harshly criticized Dong-hyuk Jang, the leader of the People Power Party, for denying the first-instance ruling that recognized the December 3 emergency martial law as a coup. Jeong claimed that Jang's refusal to sever relations with former President Yoon Seok-yeol goes beyond a simple political alliance, labeling him effectively as a spokesperson for Yoon, suggesting an alarming endorsement of Yoon's controversial government. Furthermore, Jeong declared that the events around December 3 have now made it unmistakable that the People Power Party is subject to a constitutional dissolution evaluation, indicating that their political stance undermines democratic principles.

In a series of comments, Jeong outlined that Jang’s statements reflect a profound misunderstanding of history, a betrayal of the public's trust, and a gross violation of constitutional values. He condemned the lack of basic decency and common sense in Jang’s rhetoric, describing it as both verbal abuse and a reckless assertion against the established order. Jeong emphasized that the demands of the public for a clear distinction from Yoon’s administration have been ignored, suggesting that Jang and his party have no escape from public accountability for their perceived treachery.

Additionally, Park Soo-hyun, the party's chief spokesperson, echoed Jeong's sentiments, asserting that the People Power Party’s position today could lead to historical consequences of civil unrest marked by their decisions. He expressed confidence that regardless of the name changes or rebranding efforts, the party's alignment with the actions of the coup will be indisputably exposed to the public. Park's remarks imply an escalating tension in South Korean politics, highlighting the growing demands for accountability and transparency from political leaders and parties, and raising the stakes for the People Power Party regarding their future viability.
