Medicare chief who oversaw rollout of Healthcare.gov steps down

WASHINGTON >> Medicare chief Marilyn Tavenner – who oversaw the rocky rollout of the president’s health care law – says she’s stepping down at the end of February. In an email Friday to staff at the Centers for Medicare and Medicaid Services, Tavenner says she’s leaving with “sadness and mixed emotions.” Tavenner survived the 2013 technology meltdown of HealthCare.gov, but was embarrassed last fall when she testified to Congress that 7.3 million people were enrolled for coverage.
