Maybe he just wanted some fresh air? U.S. Ambassador Jon Huntsman is making headlines in China, where he was spotted at a pro-democracy demonstration in a busy Beijing commercial neighborhood. Someone in the crowd recognized him and accused him of wanting “to see chaos in China,” which he denied before taking off. But the incident was caught on tape and is circulating on nationalist Chinese websites. The U.S. Embassy said he was en route to a museum with his family. Huntsman, a Republican and former Utah governor, is stepping down on April 30 to pursue a potential bid for the 2012 presidential nomination to run against his current boss, President Obama.
