The secretary general of the minor Korea Rebuilding Party announced his resignation Sunday, taking responsibility for a sexual misconduct scandal involving party officials.

Hwang Hyun-sun made the announcement during a press conference at the National Assembly, stating that, as secretary general, it was only appropriate for him to bear responsibility for disappointing party members and the public who had placed their trust in the party.

Hwang expressed deep regret over a series of incidents within the party, including the sexual misconduct case, and extended apologies to those affected.

He emphasized, however, that the party leadership did not intentionally delay investigations or responses in an attempt to conceal the incident.

Separately, Choe Kang-wook, head of the ruling Democratic Party's education and training institute, also offered to resign Sunday following public backlash over remarks perceived as downplaying the scandal, referring to it as a "trivial matter."

In a Facebook post, Choe stated that he believes stepping down is the least he can do for those who felt burdened or hurt by his comments.
