A dozen South Korean lawmakers will attend U.S. President-elect Donald Trump's inauguration on Monday, local time, amid domestic political turmoil. The trip comes as the official arrest of President Yoon Suk Yeol on Sunday over his botched martial law bid last month is feared to cast a heavy shadow over the Seoul-Washington alliance.

Attendees are eager to meet with key U.S. officials to discuss ways to strengthen the alliance with their security partner and enhance economic ties with the incoming Trump administration.

First off, seven members from the National Assembly's Foreign Affairs and Unification Committee, including committee chair Rep. Kim Seok-ki of the ruling People Power Party (PPP), are expected to attend Trump's inauguration as a bipartisan delegation. It will be composed of Reps. Ihn Yo-han, Yoon Sang-hyun and Kim Gi-hyeon from the PPP and Reps. Hong Kee-won, Kim Young-bae and Cho Jeong-sik from the main opposition Democratic Party of Korea (DPK).

Yoon Sang-hyun, known for his outspoken support of the embattled president, said the delegation would assure U.S. officials that South Korea's government is operating with stability.

"We will dispel international concerns about President Yoon's impeachment trial and the Dec. 3 martial law declaration. We will share people's efforts to prevent constitutional collapse and normalize the state's function," Yoon Sang-hyun said.

The delegation plans to hold meetings with U.S. Congress members including, Rep. Young Kim, Sen. Andy Kim, Sen. Chris Van Hollen and former House Speaker Kevin McCarthy. It also plans to visit the America First Policy Institute to meet with Vice Chair Fred Fleitz, a national security official during Trump's first administration.

Noting that deepening security and economic cooperation will be at the top of the delegation's agenda, DPK lawmakers vowed to emphasize that South Korea's democracy has swiftly recovered following the shocking martial law.

"We will not only congratulate President Trump on his inauguration but ask him to play an active role for peace on the Korean Peninsula. We will also meet with Congress members and think tank researchers to deliver our commitment to deepening the ROK-U.S. security alliance and expanding strategic partnership in economic cooperation," Cho said.

Separate from the bipartisan delegation, Representatives Na Kyung-won, Kang Min-kuk, Cho Jung-hun and Kim Dai-sik of the PPP will also attend the inauguration ceremony and the subsequent balls.

"We will hold in-depth discussions (with key U.S. lawmakers and officials) on ways to respond to escalating security threats such as North Korea's nuclear advancements and its close military ties with Russia, including South Korea's attempt to go nuclear," Na said.

The PPP lawmakers also aim to discuss measures to protect the rights and interests of Korean companies, which are expected to face stricter regulatory scrutiny under key U.S. legislation, including the Inflation Reduction Act and the CHIPS and Science Act.

"We will address our concerns related to the tariffs and reduction of subsidies that Korean companies in the U.S. are experiencing and persuade U.S. officials to help resolve these issues," she added.

In addition, they are scheduled to attend a roundtable meeting with the Center for Strategic and International Studies — a nonprofit, bipartisan policy think tank in the U.S. — while holding meetings with U.S. Congress members.

Na is known to have close connections with Sen. Bill Hagerty and former U.S. National Security Adviser John Bolton. Reps. Cho Jung-hun and Kim Dai-sik are scheduled to attend the presidential inaugural ball and meet with Donald Trump Jr., the U.S. president-elect's first son, during their visit, according to Cho's office.

Rep. Kim Eun-hye of the PPP also plans to attend Trump's inauguration while holding meetings with U.S.-based nuclear power and artificial intelligence experts. Daegu Mayor Hong Joon-pyo and Incheon Mayor Yoo Jeong-bok will also attend Trump's inauguration ceremony.
