Washington - Rahm Emanuel, the new chief of staff under president-elect Barack Obama, is a long-time Washington insider known for a hard-nosed but successful style.
Emanuel, 48, served as a senior advisor in the administration of former president Bill Clinton, distinguishing himself during Clinton's unlikely rise to power in 1992.
After being elected to the House of Representatives in 2002 from a district in his home town of Chicago, Emanuel rose quickly through the ranks in Congress.
