In his capacity as chief of the Seoul Central District Prosecutor's Office, he played a key role in convicting former presidents Park Geun-hye and Lee Myung-bak for abuse of power.

[5][6] Yoon's clashes with the Moon administration prior to his resignation as prosecutor general in March 2021 led to his rise as a potential presidential candidate among conservative voters.

[22][23] His father, Yoon Ki-jung, was born in Nonsan,[24] and was a professor emeritus of economics at Yonsei University and a full member of the National Academy of Sciences of the Republic of Korea.

[26] Shortly after the Gwangju Uprising, Yoon and his colleagues held a mock trial where he acted as a prosecutor, demanding the death penalty for President Chun Doo-hwan.

[42][43] Choo attributed her decision to Yoon's failure to submit a reorganization plan for his department, which she had requested, but this was seen as retaliation by the Blue House for Cho Kuk's prosecution.

[48] On 24 November 2020, Minister of Justice Choo Mi-ae suspended Yoon from his position, citing alleged ethical violations, abuse of power, and interference in investigations of his associates and family members.

[61][62] In August, Yoon stated that South Korea's recent feminist movement was a significant contributing factor to the issue of the nation's low birth rates.

[61] Later that same week, Yoon claimed during an interview with Busan Ilbo that there was "basically no radiation leak" from the Fukushima Daiichi nuclear disaster because "the reactors themselves didn't collapse".

[67] During primary debates amongst PPP presidential candidates, Yoon appeared to have the hanja character for "king" written on his left palm, a shamanist talisman for good luck.

[72] Chun Doo-hwan, a widely maligned figure in South Korea, was responsible for numerous human rights abuses, including the torture and killings of innocent civilians.

[86] On 20 March 2022, Yoon announced that he would establish his presidential office in the Ministry of National Defense building in Yongsan District, Seoul, instead of the Blue House, which opened to the public as a park on 10 May 2022.

Pro-government advertisements featured the president's commitment and included promotional videos in movie theater displays on public buses and subways, while screens inside apartment elevators criticized "emergency room ping-pong" and "pediatric clinic open run".

[124] He also attended the United Nations General Assembly and Global Fund's Seventh Replenishment Conference in New York City; he additionally met with U.S. President Joe Biden.

In his speech to G7 members, Yoon stressed South Korea's continued commitment to maintaining the international rule of law and the need to protect Ukraine's freedom and peace.

[127] During U.S. House Speaker Nancy Pelosi's visit to South Korea on 4 August 2022, which was part of a larger tour of Asia, Yoon snubbed a meeting with her, stating that he wanted to enjoy his vacation.

[133] According to a Yonhap article published on 7 November 2024, Yoon had a 12-minute phone call with the 45th president and the 47th president-elect of the U.S., Donald Trump, where they talked about trilateral cooperation with the U.S. and Japan, as well as the North Korean situation involving Ukraine.

The three announced the Camp David Principles, a set of strategies to counter the influence of China, North Korea, and Russia as well as limit the risk of economic disruptions in the future.

[158] Some sources criticized the compromise between the Japanese LDP and Yoon governments to list Sado mine as a World Heritage Site, which distorted history by removing direct references to "forced labor" by Koreans.

[159][160] In a Reuters interview on 19 April 2023, Yoon hinted at supplying lethal aid to Ukraine, stating that "If there is a situation the international community cannot condone, such as any large-scale attack on civilians, massacre or serious violation of the laws of war, it might be difficult for us to insist only on humanitarian or financial support."

[174][175] On 21 September 2022, after chatting with U.S. President Joe Biden outside the seventh Global Fund meeting in New York City, Yoon was filmed telling his aides and top diplomats, "Wouldn't [inaudible] lose face if these saekki do not pass it in the legislature?

"[176] Although the audio is hard to discern, MBC, which broke the story on air, determined in its subtitles that he said "Biden" in an apparent reference to the latter's bid to increase the American contribution to the Global Fund by $6 billion, an act that would require congressional approval.

[180] The Korean Ministry of Foreign Affairs sued MBC "to restore trust in diplomacy"; this has been likened to the oppression of journalists by the Lee Myung-bak government in the past.

[182] Yoon was accused of covering up for senior military officials over the deaths of one South Korean marine in 2023 and two more soldiers in 2024 by blocking bills seeking to investigate the matter.

President Yoon Suk-yeol's coercive measures to punish members of the former Moon administration, along with attacks on gender equality, set South Korea to decrease its LDI levels, forming a bell-turn.

[203] As part of this, Yoon allegedly ordered the flying of drones into North Korea to provoke an armed conflict between the two countries, without the knowledge of the Ministry of National Defense or the Joint Chiefs of Staff.

[209] On 9 December 2024, the Ministry of Justice issued an overseas travel ban against Yoon following an investigation into allegations of rebellion linked to his brief imposition of martial law.

[211] Despite being suspended from public duties, Yoon will receive a 3 percent increase of about 7.5 million won to his salary compared to the previous year, according to the Ministry of Personnel Management.

[220] On 7 December, Yoon apologized for declaring martial law, describing it as a "desperate decision made by me, the president, as the final authority responsible for state affairs" and saying that it would not be repeated.

[233] On 31 December, the Seoul Western District Court issued an arrest warrant for Yoon with charges relating to abuse of power and orchestration of the 2024 South Korean martial law crisis.

[274] Kim has faced an investigation that alleged she had taken kickbacks for hosting art exhibitions, in addition to reports that circulated in the South Korean media that she inflated her resume with connections to New York University Stern School of Business.
