On the morning of the 3rd, the special investigation team summoned Kim Joo-hyun, former chief of civil affairs in the presidential office, for questioning.
The special investigation team is expected to broadly question Kim regarding the declaration and lifting of the martial law. The team is investigating the circumstances surrounding the creation and subsequent disposal of a new martial law declaration document after the declaration by former President Yoon Suk-yeol.
The 'declaration of martial law' distributed to cabinet members on the day of the martial law reportedly lacked signature lines for the Prime Minister and the Minister of National Defense. Subsequently, suspicions arose that Kang Yi-gu, former head of the presidential office's secretariat, asked Kim Joo-hyun if there existed a document signed by the Prime Minister and relevant cabinet members and that he added related content to obtain signatures.
Kim Joo-hyun is also one of the members who met with former President Yoon the day after the martial law at the presidential villa in Samcheong-dong, Seoul.
Meanwhile, the special investigation team also summoned Kim Seong-hoon, former vice administrator of the Presidential Security Service, around the same time. Kim is suspected of obstructing the execution of an arrest warrant against former President Yoon Suk-yeol by the police and the Corruption Investigation Office for High-ranking Officials in January. He is also suspected of having instructed the deletion of records on the presidential secret phone server following the lifting of the martial law on Dec. 3 at the direction of former President Yoon.
