Rep. Darrell Issa, R-Calif., subpoenaed the Health and Human Services Department late Wednesday, a House Oversight Committee spokeswoman said.
The subpoena requested unredacted documents containing information about HealthCare.gov's technical problems, user capacity, testing, design, and software problems. Issa is also seeking information about testing and technical issues in the federal data hub and exchanges.
During congressional hearings earlier this week, both HHS Secretary Kathleen Sebelius and the Centers for Medicare and Medicaid Services Administrator Marilyn Tavenner declined to offer enrollment specifics. Issa's subpoena requested the number of health insurance enrollment attempts on HealthCare.gov and the total enrollment number. HHS has said on multiple occasions that it would release monthly enrollment reports and anticipates that October's report will be released by mid-November.
Issa's request coincides with the release of a CMS memo signed by Tavenner on Sept. 27 indicating a high-risk security threat with HealthCare.gov, and a HealthCare.gov contractor's report sent to HHS earlier in September that signaled there was not enough time to complete necessary testing of the website.
"The Administration's failure to provide answers about what led to the disastrous launch of HealthCare.gov and what is being done to fix it is completely unacceptable," Issa said in a press release. "The evidence is mounting that the website did not go through proper testing, including critical security testing, and that the Administration ignored repeated warnings from contractors about ongoing problems."
The deadline for HHS to respond to the subpoena is Nov. 13 at noon, according to the release.
