Ten Republican senators have called on President Obama to fire Health and Human Services Secretary Kathleen Sebelius, who is overseeing the implementation of the Affordable Care Act and its troubled website. Sen. Pat Roberts (R-Kan.) and nine other senators told Obama they were concerned not only with the botched rollout of healthcare.gov, but the implementation of the broader law, which they all oppose. Dozens of House Republicans have also pushed for Sebelius' dismissal. The White House has repeatedly said it would not dismiss Sebelius, who was a popular two-term governor of Republican-heavy Kansas before taking the post.
