Christian Science Monitor: FBI agents executed search warrants Thursday at the headquarters of California solar panel manufacturer Solyndra, which received more than $500 million in federal loans before filing for bankruptcy last week. Blue-jacket-clad agents swarmed the company's headquarters in Fremont as part of an investigation with the Department of Energy's Office of Inspector General into the manufacturer once touted by President Barack Obama as a beneficiary of economic stimulus, FBI spokeswoman Julianne Sohn said.
