Tavenner apologizes for health site delays, cites progress

More than 700,000 people have created accounts to buy health insurance on state and federal health care exchanges since they opened Oct. 1, the director of the Centers for Medicare & Medicaid Services said Tuesday, although the site has been plagued by problems. Marilyn Tavenner apologized for the site's problems in her testimony before the House Ways and Means Committee, but said the agency is steadily adding more capacity to the system. "The experience on HealthCare.gov has been frustrating for many Americans," Tavenner said.
