Office of Management and Budget director Peter Orszag will leave the Obama administration in the next few weeks, Democratic sources familiar with the situation tell ABC News.
The administration declined to comment, but Orszag was director of the Congressional Budget Office for two years before becoming OMB in January 2009. Eighteen months is approximately the median amount of time for the OMB director position, and Orszag is said to want to move on, having served in his position during the passage of the $862 billion stimulus bill and the nearly $1 trillion health care legislation.
Now would be a good time to leave in order to get a successor in place: If Orszag were to stay on much longer into the summer, he would get into the next round of budgets.
A possible replacement is Gene Sperling, a counselor to Treasury Secretary Tim Geithner.
Bloomberg News's Hans Nichols reported earlier today that Orszag was planning on leaving in the next few months.
