Obama nominates 'great team' McCarthy for EPA, Moniz for Energy chief

Burwell has long been considered the leading choice for the director's spot at the Office of Management and Budget. She served as deputy director of the agency from 1998-2001 during the nation's last budget surplus under President Clinton.
