United States Health and Human Services secretary Kathleen Sebelius resigned from her position today, some six months after the debacle that was the rollout of health insurance marketplace Healthcare.gov. Sebelius, who held the spot for five years, will likely be replaced by Sylvia Burwell following a formal nomination from President Obama tomorrow morning, reports The New York Times. The paper added that the decision was Sebelius' following conversations with the President about her future.

Healthcare.gov's launch — which Sebelius oversaw — was stymied by numerous problems, not the least of which were people being unable to enroll, or running into issues getting the site to load. It was so bad, in fact, that only six people were able to enroll in programs during the first day the site was online.

Sebelius took office in April, 2009 after serving as the Governor of Kansas. Before that she was the Kansas Insurance Commissioner and a member of the Kansas House of Representatives. Her resignation comes less than two weeks after the end of enrollment at Healthcare.gov, a date that was extended by another six weeks following additional issues with the site. US health officials announced earlier today that more than 7.5 million people had signed up for the service since its launch, a figure that was bolstered by a recent campaign by President Obama. That campaign was seen on places like Quora, as well as Funny Or Die's Between Two Ferns with comedian and actor Zach Galifianakis, which quickly became Healthcare.gov's top referrer.
