WASHINGTON (AP) - A senior administration official says President Barack Obama will nominate Walmart's Sylvia Burwell as his budget chief.

Obama will announce Burwell's nomination Monday. Burwell runs the Walmart Foundation, a philanthropic arm of the retail giant.

Burwell previously served as the deputy director of the Office of Management and Budget during the Clinton administration. If confirmed by the Senate, she would replace acting OMB director Jeffrey Zients.

The official requested anonymity in order to confirm the nomination ahead of Obama's announcement.
