South Korea President Park Geun Hye had a successful trip to the White House and Washington, D.C. -- her spokesman did not.

The Korean government announced that presidential spokesman Yoon Chang Jung has been dismissed over allegations he groped a 21-year-old embassy intern during Park's trip to D.C. this week.

"He was involved in an unsavory incident" and "displayed inappropriate behavior for a high-level official that was believed to hurt national dignity," presidential press secretary Lee Nam Ki said.

From ABC News:

"The summit with U.S. President Barack Obama and President Park's speech at Congress this week had been well-received, both heads of state presenting a united front against North Korean threats and visions of a stronger alliance ahead.

"On the evening of the summit, Yoon apparently drank alcohol with the intern at another hotel lobby close to where he and the President Park's team were staying, according to Yonhap News Agency.

"South Korean media New Daily reports that Yoon actually drank with the intern and his driver, and then went for another drink at his hotel room, this time inviting only the intern. He was allegedly wearing 'underwear' when she showed up.

"The intern reported the incident to the police. The next day while President Park was delivering a speech to the Congress, Yoon abruptly took a taxi to Dulles Airport, bought a business class ticket, and flew back to South Korea. He reportedly left all his belongings at the checked-in hotel."
