South Korea's president vows to fight on

On Thursday, South Korea's embattled President Yoon Suk-sol vowed to fight on until "the very last minute" as members of his own party seem poised to side with the opposition in a second impeachment vote this weekend. Yoon justified his declaration of martial law last week as defending South Korea's democracy against "legislative tyranny."
