Lawmakers have questions about how and why HealthCare.gov did not work as advertised, whether the federal website meets government security standards and how much all the repairs are costing.
In a blog post early Wednesday, Sebelius said that she has asked the department's inspector general to investigate how HealthCare.gov went off track. She wants an independent review of the contracting process, management, performance and payment issues that may have contributed to the flawed launch.
The administration report found a total of 137,204 people enrolled in the states served by the federal website by the end of November, up from 26,794 in October.
The 14 states running their own websites enrolled 227,478 people, up from 79,391 in October.
