The following editorial is from the Chosun Daily News on President Park's initial written defense statements submitted at the impeachment hearings. The editor asks if President Park is crazy for sticking to her story that she did not know about any criminal activities of those around her, the sports and culture foundations were set up and funded voluntarily, and that she was working at the Presidential residence during the Sewol Ferry tragedy and that she promptly reacted to the situation. This goes against all the recorded phone conversations, instant messages, written notes and witness testimony. The editorial details the President's defense and how it contradicts the facts based on evidence.
Chosun Ilbo (Daily News): Has Park Lost Her Grip on Reality?
The Constitutional Court which is hearing the impeachment case against President Park asked her to submit details of her whereabouts and actions on April 16, 2014, the day of the Sewol Ferry tragedy. Everyone has asked, but she has never answered. Now, she has to answer or forfeit. No escape.
Saenuri Party member, Yi Wan-yong, was is accused of promoting witness perjury was caught on picture with members of a regional association drinking heavily at dinner several years ago. In the picture is the lawyer of Choi Soon-sil and a close associate of Woo Byung-woo. Many members of this association are linked to the Choi Soon-sil scandal. Saenuri Party member Yi Wan-yong has questioned witnesses with a strong prejudice towards questions to help Choi Soon-sil's defense. He denies all allegations, but he is under investigation and I suspect he will be found guilty. It will be hard to find concrete evidence. but I hope they find some.
