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 Korea's impeached President Yoon Suk Yeol was arrested Sunday, just days after being apprehended at his home in Seoul. He faces possible imprisonment for declaring martial law last month.

South Korean President Yoon Suk Yeol is expected to make his first appearance at his impeachment trial on Tuesday, with security ramped up following the Capitol Hill-like rioting during his appearance at another court at the weekend.
