(AP) — Federal prosecutors say a Northern California man has been charged with stockpiling weapons, including pipe bombs, and the FBI said he sent texts that could be seen as threats against the governor's office. The Justice Department announced weapons charges against Ian Rogers of Napa on Wednesday after weapons and explosives were found at his home and auto repair shop. An FBI court affidavit says Rogers talked about wanting to blow up a building and made references that could be to the governor's office and Twitter and Facebook headquarters. His attorney says the texts were just "drunken bluster."
