2014: In the wake of the botched rollout of HealthCare.gov, Kathleen Sebelius (far right) resigns as Secretary of the United States Department of Health and Human Services. During the same news conference, President Barack Obama also announced he was nominating Sylvia Mathews Burwell (second from right), the director of the Office of Management and Budget, to replace Sebelius. Burwell's nomination was confirmed by the Senate in June 2014.
