President Moon has to get someone appointed as the Justice Minister to slow down all the corruption investigations into the Blue House:
Choo Mi-ae, a five-term ruling party lawmaker, has been nominated for the position of justice minister, Cheong Wa Dae announced Thursday amid keen attention to her role in the South Korean government’s push for prosecution reform.
President Moon Jae-in picked Choo to fill the post that has been vacant for several weeks since Cho Kuk stepped down in the face of state prosecutors’ probe into alleged irregularities involving his family. (……..)
For Moon, the choice of Choo is viewed as a card to counter the prosecution’s thinly veiled pressure on Cheong Wa Dae with intensive probes into high-profile corruption suspicions, involving longtime confidants to the president, under the leadership of Prosecutor General Yoon Seok-youl.

Speculation is running high that Choo will shake up the prosecution as soon as she becomes minister. As of now, the prosecution is carrying out at least three investigations that involve allies of President Moon. Probes are ongoing into an allegation that the Moon Blue House carried out a political operation to influence the 2018 local election; the suspicious suspension of a Blue House probe into Moon’s associate Yoo Jae-soo; and the continuing investigation of corruption allegations involving Cho Kuk and his family.
