The Grand National Party on Friday disclosed a CD containing conversations between one of Kim’s American fellow inmates at a Los Angeles detention center and his lawyer, while citing an article of a newspaper. The fellow prisoner told his lawyer about the involvement of high-ranking Korean pro-government officials and their attempt to make a big deal with Kim.

According to the English conversations recorded in the CD, Mr. Zigetta, the fellow convict, said, “I think people who seemed to be top level pro-government officials from Korea visited him (Kim Gyeong-jun) from March. Kim told me that things are going smoothly and they proposed him a special deal.”

“Kim Gyeong-jun told me that he had to testify something he knows in return for a pardon or a lighter punishment,” he added.

The GNP not only launched its own investigation team to probe the claim, but also called for prosecutors to immediately launch an investigation into the allegations.

“The prosecution must dispatch prosecutors to the U.S. at once to find out who visited Kim. A simple examination of the list of visitors to him in the detention facility will suffice to unveil the purported visitors,” said Ahn Sang-soo, floor leader of the GNP.

"It is time for United New Democratic Party candidate Chung Dong-young to answer whether he was directly involved in the dealing with Kim Gyeong-jun and whether he orchestrated Kim’s return," said Na Gyeong-won, GNP spokesperson.

In response, Rep. Chung Bong-ju of the United New Democratic Party said, “Lawyers have to pass a thorough security check like that of the airport at the Los Angeles Federal Detention Center. Therefore, they cannot enter with any type of (recording) device.”

“Attorney Dennis Jang, who conducted the interview with Mr. Zigetta, has been renting the DAS’s lawyer’s office which belongs to candidate Lee Myung-bak’s older brother and his brother-in-law. His identity arouses suspicion,” Rep. Chung added.

However, Jang refuted the claim in an interview with media. “Although my office is in the same building, I have been running a separate office for a long time. Chung’s claim that devices like recorders are not allowed shows that he doesn’t understand the situation in the U.S.”
