John Podesta, a former chief of staff for President Clinton, told Bloomberg News' Al Hunt "virtually the whole Cabinet" will be in place by the end of the year.
Earlier this week President-elect Obama announced he was nominating New York Fed chairman Timothy Geithner to be his Treasury Secretary. He has also reportedly settled on Sen. Hillary Clinton for Secretary of State, New Mexico Gov. Bill Richardson for Commerce Secretary, Arizona Gov. Janet Napolitano for Homeland Security Secretary, former Sen. Tom Daschle for Heath and Human Services Secretary, and Eric Holder for Attorney General. Obama also reportedly favors keeping Defense Secretary Robert Gates in his current position.
Though Gates currently appears to be the only Republican set to hold a leading cabinet post under Obama, Podesta said there will be "multiple Republicans" in the administration.
