On the afternoon of Sept. 21 local time, presidential secretariat chief Kang Hoon-sik told President Lee Jae-myung he wished to resign. South Korean analysts link the move to controversy over Lee's recent personnel reshuffle. At a Sept. 18 press conference Lee apologized for falling approval and the reshuffle after reporters raised questions about lax vetting of appointments.
