Lee Jae-myung, leader of the Democratic Party of Korea, said, "I believe the Constitutional Court will do well (on the impeachment trial of President Yoon Suk-yeol)," and claimed, "President Yoon tried to create a Korean version of the killing fields (the incident where a militant group massacred opposition forces after seizing power in Cambodia).
On the 12th, during the emergency meeting of the Democratic Party on overcoming internal strife in front of Gwanghwamun in Seoul, Lee said in his opening remarks, "How would the Constitutional Court make a decision that goes against common sense and historical responsibilities?"
Lee raised a question, saying, "If the impeachment of President Yoon is dismissed as some in the People Power Party expect, and the president returns to office, what would happen?" and continued, "Doesn't that imply that, in the name of the Constitutional Court, the president can deploy the military and declare martial law at any time to enlighten the people?"
He added that, "In a notebook written by former National Intelligence Service Director Noh Sang-won, there's a scene where they consider other methods because there's a plan to collect 500 people first, blow up a boat in the sea going to Yeonpyeong Island, and kill 5,000 to 10,000 people the same way in 10 stages." He pointed to President Yoon's military governance plans.
He also raised his voice in criticism against the ruling party, which defends the release of President Yoon. Lee stated, "Even if we leave the impeachment trial problem to the Constitutional Court, which is composed of the nation's greatest intellects, the People Power Party, which will take part in the politics of this country, is defending a major crime lord that destroys the Constitution and is justifying bizarre acts of release."
Lee remarked, "The People Power Party will soon say, 'I don't know, it has nothing to do with me, I reflect,' but can that be sincere?" He added, "As one of the politicians, we also feel a sense of responsibility. There might be aspects where we are not proficient or perfect or are lacking in abilities."
However, he emphasized again that constitutional destruction cannot occur. Lee stated, "Shouldn't we uphold the basic order of 'the Constitution,' which is higher than the laws agreed upon by all our citizens, which is the highest agreement in this country?" He added, "We must not destroy the fundamental foundation of this democratic republic called the Republic of Korea."
On that day, the members of the non-Lee Jae-myung faction who participated in the emergency meeting spoke in unison.
Kim Kyung-soo, former governor of South Gyeongsang Province, who is on his fourth day of fasting, said, "We must end this internal strife through impeachment," and added, "Many citizens at Gwanghwamun expressed their concerns, saying they are too anxious after the release of Yoon Suk-yeol, fearing the impeachment might be dismissed."
Former Prime Minister Kim Boo-kyum expressed, "Those who gathered here are people who have often criticized the leadership of Lee," but stressed, "Nonetheless, I have never doubted that President Yoon, who is responsible for the division of public opinion, must be impeached. We must ensure the impeachment of President Yoon Suk-yeol."
Former lawmaker Park Yong-jin, former National Assembly Secretary-General Lee Kwang-jae, and former Chief of Staff to the President Im Jong-seok also urged the Constitutional Court for a swift decision to accept the impeachment of President Yoon.
