Washington ? Steven Rattner, who led the Obama administration’s efforts to restructure General Motors and Chrysler through swift, government-led bankruptcies, plans to depart his post, officials said Monday.

Rattner will be replaced by former steelworkers official Ron Bloom, who has been a key member of the task force and adviser to Treasury Secretary Timothy Geithner. The administration said Monday that Rattner had decided to return to private life and his family in New York City.
