Story from the NYT:
President Obama announced Monday that the White House chief of staff, William M. Daley, was stepping down, jolting the top ranks of his administration less than a year before he faces a difficult re-election. Mr. Daley will be replaced by Jacob J. Lew, the budget director and a seasoned Washington insider with ties to Capitol Hill.
Jacob Lew had been the head of the Office of Management and Budget, which of course means he is a budget guy.
