From NBC's Domenico Montanaro
Seriously, Richardson, the governor of New Mexico, called on the government to declassify all Roswell documents. He brought it up himself when Chris Matthews was joking about Kucinich's UFO answer. He said the government hasn't "come clean" on the issue. His campaign will surely say he was joking, he has a sense of humor. But even though he was laughing in some parts of that answer, he wasn't joking about THAT.
Matthews looked on in disbelief and joked that this is shaping up to be a contest between the de-evolution party and the pro-UFO party.
