Orszag, 41, has been a key part of Obama's economic team, serving in his role as director of the Office of Management and Budget during the passage of the economic stimulus bill and this year's health care reform legislation.
As budget director, he crafted policy, but also was a prime negotiator with congressional Republicans.
As one of the main negotiators in the final hours before lawmakers passed the economic stimulus package, Orszag tried to bridge differences and was keeper of the ever-changing numbers, often crunching them in his head.
