Sylvia Mathews Burwell appears assured of Senate confirmation after two panels today approved her nomination to head the Office of Management and Budget. Burwell’s nomination cleared both the Senate Budget Committee and the Senate Homeland Security and Governmental Affairs Committee on voice votes; a final vote by the full Senate could come within the next week. Burwell is an OMB alum from the Clinton administration who most recently headed the Walmart Foundation. If confirmed, she would replace Jeff Zients, who has served as acting OMB chief since January 2012, when Jack Lew left to become White House chief of staff.
