Lee Jun-seok, chairman of the New Reform Party, said, ”This is clearly a reason to impeach President Yoon Seok-yeol.” What did Lee point out? (South Korea)

Lee Jun-seok, the leader of the New Reform Party, who was elected as a member of the National Assembly in Eul, Hwaseong City, Gyeonggi Province, mentioned the impeachment of President Yoon Seok-yeol.
If Colonel Park Jeong-hoon, head of the Marine Corps investigation team who was indicted on charges of disobeying orders and defamation of a superior officer, is found not guilty, this will be grounds for impeachment.
On the 12th, in an interview with TV Chosun's YouTube channel "Kangpanch," Lee said, "Whether the issue of Colonel Park Jong-hoon is a special prosecutor or something else, the president is
I think that we need to look at the results of the 2016 election and immediately make a decision on whether to drop the charges. Even if Colonel Park is forced to take responsibility (as a result of the trial), President Yoon Seok-yeol
"It is a burden to me, and if he is found not guilty, I think this is grounds for impeachment. Explicitly," he continued, "The honor of a uniformed soldier named Park Jung-hoon was simply trampled on with the power of the president.
I don't think the younger generation will tolerate this," he said. "This trial must be stopped by unconditionally dropping the charges."
Colonel Park Jeong-hoon was the head of the investigation team that investigated the death of Marine Corps Corporal Choi Soo-geun in the line of duty.
The investigation into the death of Corporal Choi in the line of duty has pointed out charges of negligence resulting in death to eight people, including former Marine Corps 1st Division Commander Lim Seong-geun, for not following the order of former Minister of National Defense Lee Jong-seop to withhold the transfer.
On July 30, Lee signed the investigation report, but the next day he decided not to hand it over to the police.
There is suspicion that the decision was made under pressure from higher-ups.
