Official: Health Secretary Kathleen Sebelius Resigning

Kathleen Sebelius - who weathered heavy criticism over the flaw-filled launch of the Obamacare website, then saw the program through as it topped a major milestone - is resigning as secretary of the Department of Health and Human Services, a White House official said Thursday.

President Barack Obama intends to nominate Sylvia Mathews Burwell, current director of the Office of Management and Budget, to replace Sebelius, according to the official.

A former Kansas governor and, before that, state insurance commissioner, Sebelius was sworn in as HHS secretary in April 2009.

Her time as head of the federal health agency coincided with the passage and implementation of the Affordable Care Act, the bill often referred to as Obamacare.

Sebelius came under fire last fall for the rocky rollout ofHealthCare.gov, the website central to the new law's implementation.
