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.

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.

South Korean investigators probing President Yoon Suk Yeol for alleged insurrection asked a Seoul court on Friday to extend his detention as the embattled leader again refused to be questioned.
