It was pretty hush-hush - but (of all people!) Wolf Blitzer covered but no explanation ever given for why a "private humanitarian visit" involved them looking over computers with NK military (!?!?!):
Google's Schmidt starts North Korea trip -
"A controversial private trip to North Korea by Google Chairman Eric Schmidt and former New Mexico Gov. Bill Richardson got underway Monday, according to media reports. Despite intense media interest over the past week, few details of the trip -- which is taking place despite objections from the U.S. State Department -- were known. But broadcasters in South Korea reported the delegation flew from Beijing to North Korea on Monday, and photographers spotted Schmidt and Richardson at Beijing International Airport. Sources told CNN last week that the trip is a "private humanitarian visit." It is thought that Richardson's objective will be to try and negotiate the release of an American prisoner who was captured last month in North Korea. A brief statement released by Richardson over the weekend confirmed the pair would be joined by adviser Tony Namkung and Jared Cohen, a former State Department official who now works at Google."
