Is President Obama losing another top-ranking woman from his administration?
Deputy chief of staff Nancy-Ann DeParle is expected to leave this month, according to published reports.
DeParle, helped craft the new healthcare law, will be joining the Brookings Institution as a guest scholar in Economic Studies Jan. 28, the group's president Strobe Talbott announced.
Obama has been criticized for filling many top positions in his second term with men. Secretary of State Hillary Clinton and Secretary of Labor Hilda Solis are departing. Obama nominated Sen. John Kerry, D-Mass. to replace Clinton.
While Obama’s Cabinet remained relatively stable in his first term, several senior aides left. Political observers expect half of the Cabinet – as well as a handful of senior staffers – to change at the start of his second term. Former Presidents George W. Bush and Bill Clinton each replaced half of their Cabinets after they were re-elected.
