For the first time, someone in the Obama administration apologized for the problem-plagued Obamacare website. Marilyn Tavenner also said on Tuesday that the online troubles were being resolved and the overall program was working, albeit slower and less successfully than hoped. In the first congressional testimony from a government official on the botched launch of HealthCare.gov, the head of the federal Centers for Medicare and Medicaid Services told the House Ways and Means Committee that the "vast majority" of consumers would be able to successfully use the site by the end of November. "I want to apologize to you that the website does not work as well as it should," she said, adding that HealthCare.gov "can and will be fixed."
