Kathleen Sebelius is resigning as secretary of the U.S. Department of Health and Human Services, a White House official said Thursday.
President Barack Obama intends to nominate Sylvia 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 into her most recent position 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 of HealthCare.gov, the website central to the new law’s implementation.
