In a sign that the White House is seeking to avoid a nomination fight, an official said Obama was tapping Burwell, the director of the Office of Management and Budget, to replace Kathleen Sebelius, who has resigned as Health and Human Services Secretary. Burwell was unanimously confirmed by the Senate for her current post. (AP Photo/Carolyn Kaster, File)
