Citing national security risks, Obama on Friday, Sept. 28, 2012, blocked a Chinese company from owning four wind farm projects near a Navy base where the U.S. military flies unmanned drones and electronic-warfare planes on training missions. It was the first time in 22 years that a U.S. president has blocked such a foreign business deal. (AP Photo/Carolyn Kaster, File)
