As of my last update in September 2021, there are no reports indicating that Yoon Suk-yeol, the President of South Korea, has been impeached or is facing an arrest warrant. Yoon Suk-yeol served as the Prosecutor General and later became a presidential candidate. He was elected as President in March 2022, succeeding Moon Jae-in. It’s possible that developments have occurred after my knowledge cutoff date. For the most recent information, please consult reliable news sources.
