President Obama will announce this week that Elizabeth Warren, the Harvard Law School professor who first proposed the Consumer Financial Protection Bureau, will be named to a special position reporting to both him and to the Treasury Department and tasked with heading the effort to get the new federal agency standing, a knowledgeable Democrat told ABC News.

Warren's title will be Assistant to the President & Special Adviser to the Secretary of the Treasury on the Consumer Financial Protection Bureau.

Warren currently chairs the Congressional Oversight Panel of the Troubled Assets Relief Program and has been seen by many on the Left as a force for greater accountability and transparency, and a check against the forces in the Obama administration more closely allied with the financial sector. Many officials in that sector eye her warily as too anti-business.
