As the president awaits an impeachment trial, the country’s interim leader may face an ousting of his own. The currency has plunged as the crisis has deepened.

Acting President Han Duck-soo on Thursday said he would not appoint any justice nominees without bipartisan agreement as the opposition-controlled National Assembly on Thursday passed a bill to recommend three nominees to fill in judicial vacancies at the Constitutional Court.
