Kathleen Sebelius has resigned from her post as the secretary of the Department of Health and Human Services, a move most tea-leaf-readers in Washington see as a way for the Obama administration to move past the tumultuous rollout of Obamacare.

On Friday, Obama is expected to nominate Sylvia Mathews Burwell, currently his budget director, as Sebelius’s replacement.

Those wondering if Sebelius jumped or was pushed have been puzzling over an interview with HuffPost Live on March 30, the day before the enrollment deadline for Obamacare, in which she said she would “absolutely” remain in her position until November. “The goal really is to, for the first time, make sure people have affordable healthcare options,” she said. “This is the most satisfying work I’ve ever done.”

A White House official said that Sebelius had alerted the administration to her plan to resign in early March. When HuffPost Live host Alyona Minkovski asked Sebelius to confirm that she would be “staying for a while,” the secretary had a simple answer: “I’m in.”

The resignation gave Republicans a reason to renew their criticism of the Affordable Care Act, and many jumped at the chance. “Secretary Sebelius may be leaving, but the problems with this law and the impact it’s having on our constituents aren’t,” Senate Minority Leader Mitch McConnell said. “Obamacare has to go, too.”

“While we haven’t always agreed, Secretary Sebelius did the best she could during the tumultuous and volatile rollout of the law,” Rep. Orrin Hatch said, noting that Sebelius “had one of the toughest jobs in Washington.”

Democrats rushed to defend Sebelius—and the law. “Her legacy will be found in the 7.5 million Americans signed up on the marketplaces so far, the 3.1 million people covered on their parents’ plans, and the millions more gaining coverage through the expansion of Medicaid,” said House Minority Leader Nancy Pelosi.

In an interview about her exit, Sebelius said that, while she wished her resignation would help Democrats and Republicans come together in support of Obamacare, she wasn’t holding her breath: “If I could take something along with me,” she told The New York Times, it would be “all the animosity.”
