Medicare Chief Tavenner Steps Down, Took Part Health Care Rollout

Marilyn Tavenner, a key administration official who oversaw the wobbly rollout of Obamacare, announced Fridayshe will step down at the end of February.

Mrs. Tavenner enjoyed bipartisan support when President Obama tapped her to lead the Centers for Medicare and Medicaid Services, an agency in charge of massive amounts of health spending and President Obama’s overhaul.

But the Affordable Care Act’s disastrous rollout led to tension between her agency and congressional Republicans intent on dismantling the law. And last year, she had to walk back Obamacare enrollment figures she provided to the House oversight committee, after its staff realized the agency had lumped in hundreds of thousands of dental plans.

She joins former Health and Human Services Secretary Kathleen Sebelius as the second key Obamacare official to resign since the law kicked off in earnest in fall 2013.
