As expected Choo Mi-ae was made the scapegoat for the Prosecutor General fiasco even though she was likely taking all commands from the Blue House:
President Moon Jae-in accepted Justice Minister Choo Mi-ae’s previously offered resignation, Wednesday, following a recent court decision that granted an injunction to Prosecutor-General Yoon Seok-youl against a ministry disciplinary committee’s order suspending him from duty for two months.

Moon’s decision to replace the justice minister comes after months of calls from the public and opposition to dismiss the former five-term lawmaker of the ruling Democratic Party of Korea (DPK) who have been weary of the longstanding conflict between her and the top prosecutor. The Choo-Yoon conflict and political wrangling over the President’s push for prosecutorial reform have emerged as key factors that have significantly hurt public trust in the Moon administration.
The presidential office announced a replacement for Choo, in addition to two other ministerial posts, in a briefing the same day. The President named DPK Rep. Park Beom-kye, a former judge, to replace Choo, who will continue to serve in the post until the confirmation hearing for Park.
