Pyo announced his candidacy for the
2016 parliamentary election, saying that he wanted "to realize justice through politics". He was elected to the
National Assembly as a member of the
Democratic Party. In November and December 2016, Pyo made several comments accusing supporters of
Park Geun-hye to have mindsets of group rapists, based on
neutralization theory. At the same time, he released a list of politicians who opposed President Park's impeachment, now known as the Pyo Changwon List. This was criticized by his opponents as a direct act against
representative democracy, an act of political terrorism, and an act against the right to vote as provided by the
Constitution of South Korea. On January 20, 2017, Pyo hosted a galleria at the parliament which included artworks satirizing Park. One such artwork,
the Dirty Sleep (), depicted a naked Park and was criticized by women's rights organizations. Pyo was put under investigation by the Ethics Committee of the Democratic Party of Korea, and was banned from holding a post within the party for six months. == Post-political life ==
