Elijah Cummings, D-Md., on Capitol Hill in Washington, before the start of the committee's hearing on the implementation of the Affordable Care Act’s HealthCare.gov website. The top cybersecurity officer for the federal Health and Human Services department was concerned about potential vulnerabilities ahead of the launch of the Obama administration’s health care website. Issa, investigating the chaotic rollout of the website contends the administration risked the personal information of millions of Americans in its zeal to meet a self-imposed Oct. 1 deadline. Cummings says the administration addressed the potential security issues through added vigilance instituted before the site went live. (AP Photo/J. Scott Applewhite, File)
