Health and Human Services Secretary Kathleen Sebelius said Wednesday that the ailing health insurance website was improving thanks to "relentless" efforts to work out the bugs, and she cited an uptick in enrollment as evidence that the program is back on track after a false start.
But she told a congressional panel she has launched an investigation into what policies and management failures may have contributed to the initial failures of HealthCare.gov, the main portal for people in 36 states to buy private insurance plans under the health-care law.
The administration announced Wednesday that about 365,000 Americans chose health plans during the first two months of the federal and state insurance marketplaces, bringing the total to more than triple the meager enrollment from October.
