The Obama administration's top health official is visiting South Florida to talk up the Affordable Care Act as fallout from the new law grows.

Department of Health and Human Services Secretary Kathleen Sebelius will be in Miami on Tuesday to discuss website enrollment.

Sebelius and Obama have repeatedly apologized for a dismal launch of Healthcare dot gov, which consumers in 36 states were supposed to use beginning on Oct. 1 to sign up for coverage.
