Health and Human Services Secretary Kathleen Sebelius said Friday that the health care website is being fixed and remained optimistic that the number of Americans enrolling for insurance through the marketplaces will increase.
"The system is working a lot more smoothly for a lot of people now," said Sebelius at an education and outreach session at the Community Health and Social Services (CHASS) Center in southwest Detroit. "We want people to use the website—it's very much up and running and it's working."

Sebelius also answered several questions from participants regarding President Barack Obama's recent health-care law fix, which will allow a one-year health plan renewal for insurers whose policies would otherwise be canceled.
