South Korean President Yoon Suk Yeol appeared in a Seoul court for his impeachment trial Tuesday, defending his short-lived martial law bid and denying charges that he ordered the military to drag lawmakers away.

He has been incarcerated for the past week, while investigators probe his botched attempt to impose martial law in early December.

South Korea’s impeached president has denied that he ordered the military to drag lawmakers out of the National Assembly to prevent them from voting to reject his martial law decree last month, as he appeared for the first time before the Constitutional Court that will determine his fate.
