Ask what Korea is talking about.

The ruling Democratic Party (DP) decided Tuesday to seek a parliamentary investigation into Supreme Court Chief Justice Cho Hee-dae, with some hardliners calling for his impeachment over allegations, Yonhap and the Korea Times report. The main opposition People Power Party (PPP) denounced the move, with its floor leader criticizing the decision, according to KBS World. The DP's floor spokesperson Jeon Eun-su told reporters Tuesday that the party's lawmakers had decided to push the probe, KBS World adds. The decision follows earlier reports that the DP was considering such an investigation amid internal debate over impeachment, the Korea Times noted on Oct. 21.
