The White House continues to reject calls for delaying parts of the new healthcare law due to the troubled rollout. Appearing before the Senate Finance Committee, Health and Human Services Secretary Kathleen Sebelius said delay is off the table.

Kathleen Sebelius: “People’s lives depend of this. Too many hard-working people have been waiting for too long for the ability to obtain affordable health insurance. If we want to save families from going bankrupt, if we want to save the lives of more of our friends and neighbors by allowing them to detect medical issues early, if we want to keep prices down, delay is not an option.”

Sebelius said figures set for release next week will show enrollment to be low, but the administration remains confident it can hit its target of signing up seven million Americans for insurance plans by March. Democratic Sen. Max Baucus, a co-author of the healthcare law, criticized the rollout’s troubles.

Sen. Max Baucus: “When we asked for updates on the marketplaces, the responses we got were totally unsatisfactory. We heard multiple times that everything was on track. We now know that was not the case. But that’s in the past. Now it’s time to move forward and figure out how to fix it.”

Wednesday’s hearing came as a top official at the federal agency responsible for the federal healthcare website resigned. Tony Trenkle served as chief information officer at the Centers for Medicare and Medicaid Services. Trenkle is taking a job in the private sector. It is unclear if his departure is linked to the website’s troubles.
