It is very unfortunate that he changed his testimony. He has changed his story, but the essence of his testimony is what is happening in North Korea, especially in the political prisoner camps. He changed his story of how he was tortured at age 20 and said 13 instead of 20, and he said that he was ill-treated in Camp 18 instead of Camp 14, and therefore the credibility of his testimony is being tested. That is very unfortunate, but as I said, what's happening in North Korea in the prison camps is true. I think that's why it won't affect much; to some extent, yes, but not really.
