Rep. Kim Sang-wook's banner installed in favor of impeachment is abusive.

Police have launched an investigation after abusive language was found on a banner posted by Kim Sang-wook, a member of the National Assembly in Nam-gu, Ulsan, who expressed his support for the impeachment of President Yoon Suk Yeol.

A banner hung near Representative Kim's Ulsan office said, "I apologize for the martial law disaster," and swear words were written in red paint on it.

The banner was installed by Representative Kim's office on the afternoon of the 14th, the day of the impeachment of President Yoon, and police are looking for people who scribbled by analyzing CCTV and others.
