Former President Bill Clinton has made a surprise visit to North Korea to try to win the release of two jailed US journalists. Euna Lee and Laura Ling of Current TV were sentenced to twelve years of hard labor following their arrest on the North Korea-China border in March.

Clinton may also discuss North Korea’s nuclear program during the trip. North Korea’s chief nuclear negotiator greeted Clinton when he landed earlier today in Pyongyang. Clinton is the highest-profile American to visit North Korea since his own secretary of state, Madeleine Albright, went there in 2000. The trip marks President Clinton’s first diplomatic mission abroad for the Obama administration.
