During the second joint debate for the Democratic Party's primary for Seoul mayor, candidates expressed differing opinions on whether broadcaster Kim Eo-jun should apologize regarding allegations of a 'prosecution cancellation transaction theory.' While all but one candidate, Park Joo-min, agreed that an apology was necessary, Park suggested that the need for an apology might depend on Kim's prior knowledge of the statements made. This conversation emerged in the context of the party's response to alleged conspiracy theories associated with President Lee Jae-myung, which some candidates condemned as defamatory.

In a political atmosphere charged with accusations surrounding a conspiracy theory linking former MBC journalist Jang In-soo to the Democratic Party, the candidates were clearly focused on maintaining their party's integrity. Jeong Won-o and Jeon Hyun-hee made strong statements denouncing the allegations as an attack on President Lee, arguing that such claims should be actively challenged by the party. These remarks highlight the tension within the party as they strive to present a united front in the face of damaging accusations.

The debate also took a turn toward internal party dynamics, with Park Joo-min questioning Jeong Won-o's connections to businesses embroiled in controversies, thereby revealing concerns about conflict of interest within the leading candidate. This tension suggests that the candidates are not only in competition for votes but are also navigating complex narratives surrounding credibility and ethical affiliations, ultimately shaping the Democratic Party's strategy as they prepare for the elections ahead.
