Administration officials have confirmed that budget director Peter Orszag will leave his post in July, making him the first member to leave Obama's Cabinet. Presidential advisers have named two likely successors: Laura D’Andrea Tyson of Berkeley's Haas School of Business, a member of the President’s Economic Recovery Advisory Board, and Gene Sperling, a counselor to Treasury Secretary Tim Geithner. Sources report that Orszag had been debating leaving this summer or early next year: "He went back and forth and couldn’t quite commit,” a colleague of Orszag's told Politico. Reportedly, Orszag is itching to move on after guiding the White House and Congress through such massive expenditure laws as the stimulus bill and the health-care overhaul. Orszag led the Congressional Budget Office for two years before heading to the Office of Management and Budget in 2009.
