Obama is moving quickly to put his administration together and has given the Chief of Staff role to Rahm Emanuel, Democratic Representative from Illinois. According to the AP, "Several Democrats confirmed that Emanuel had been offered the job. While it was not clear he had accepted, a rejection would amount to an unlikely public snub of the new president-elect within hours of an electoral college landslide."
Obama has ten weeks to fill hundreds of positions, including his top level cabinet.
Emanuel was a political and policy aide in Bill Clinton's White House. Leaving that, he turned to investment banking, then won a Chicago-area House seat six years ago. In Congress, he moved quickly into the leadership. As chairman of the Democratic campaign committee in 2006, he played an instrumental role in restoring his party to power after 12 years in the minority.
