Former Health and Human Services Secretary Kathleen Sebelius

The Obama administration's timeline for having ready the new health care law's online sign-up system "was just flat out wrong," outgoing Health and Human Services Secretary Kathleen Sebelius said in an interview that aired Sunday.

The departing health chief also said the two months when healthcare.gov was plagued with technical problems were "a pretty dismal time" and the low point of her five-year tenure. But she defended the law's impact and said millions of Americans now have access to health care because of it. (AP)
