Concerns raised about security of health website

Health and Human Services Secretary Kathleen Sebelius gestures while testifying on Capitol Hill in Washington, Wednesday, Oct. 30, 2013, before the House Energy and Commerce Committee hearing on the difficulties plaguing the implementation of the Affordable Care Act. The Obama Administration claims the botched rollout was the result of contractors failing to live up to expectations – not bad management at HHS. As the public face of President Barack Obama's signature health care program, Sec. Sebelius has become the target for attacks over its botched rollout with Republicans, and even some Democrats, calling for her to resign. (AP Photo/J.
