President Bush nominated Trade Representative Rob Portman as the White House budget director, turning to a Washington insider and longtime friend as part of an effort to re-energize the administration and boost the president's record-low approval ratings. Mr. Bush also selected Susan Schwab, the deputy trade representative, to move up to the top job, replacing Mr. Portman. If confirmed by the Senate, Mr. Portman will succeed Joshua Bolten, who stepped down as director of the Office of Management and Budget to become White House chief of staff.
