CBS News reports:

CBS News has learned that the project manager in charge of building the federal health care website was apparently kept in the dark about serious failures in the website's security. Those failures could lead to identity theft among buying insurance. The project manager testified to congressional investigators behind closed doors, but CBS News has obtained the first look at a partial transcript of his testimony.

Henry Chao, HealthCare.gov's chief project manager at the Centers for Medicare and Medicaid Services (CMS), gave nine hours of closed-door testimony to the House Oversight Committee in advance of this week's hearing. In excerpts CBS News has obtained, Chao was asked about a memo that outlined important security risks discovered in the insurance system.

Chao said he was unaware of a Sept. 3 government memo written by another senior official at CMS. It found two high-risk issues, which are redacted for security reasons. The memo said "the threat and risk potential (to the system) is limitless." The memo shows CMS gave deadlines of mid-2014 and early 2015 to address them.
