Aaron Alexis, the 34-year-old suspect in Monday's shooting rampage at the Washington Navy Yard, had "Secret" clearance and was assigned to start working there as a civilian contractor with a military-issued ID card, his firm's chief executive told Reuters. "He did have a Secret clearance. And he did have a CAC (Common Access Card)," said Thomas Hoshko, CEO of The Experts Inc, which was helping service the Navy Marine Corps Intranet as a subcontractor for HP Enterprise Services, part of Hewlett-Packard Co. Alexis had previously worked for The Experts in Japan from September 2012 to January 2013, he said. "We had just recently re-hired him. Another background investigation was re-run and cleared through the defense security service in July 2013," Hoshko said. Hoshko said he believed that Alexis's "Secret" security clearance dated back to 2007.
