White House Budget Director Peter Orszag will step down from his post in the next few weeks, several news outlets reported Monday night.

Kenneth Baer, a spokesman for the White House’s Office of Management and Budget, said late Monday night that he could not confirm that Orszag is leaving. The Washington Post and Reuters cited anonymous sources confirming the OMB director’s departure.

Orszag’s exit would make him the first member of President Barack Obama’s Cabinet to leave. As OMB director, he has played an important role in helping to advance two of the president’s key legislative efforts: a health care overhaul and economic stimulus legislation.
