Democratic officials say Barack Obama’s fellow Chicagoan Rahm Emanuel has agreed to be White House chief of staff. One of Obama’s first decisions as president-elect was to ask the Illinois congressman to run his White House staff.

Emanuel accepted Thursday after struggling over family and political considerations. Emanuel serves in the House Democratic leadership and will have to resign his seat and put aside hopes of becoming House Speaker.

Emanuel is a fiery Democrat who served as a political and policy aide in the Clinton White House. His selection is a shift in tone for Obama, who chose more low-key leadership for his presidential campaign.
