Source: Rahm Emanuel expected to resign

In this April 27, 2010 file photo, White House Chief of Staff Rahm Emanuel laughs as he takes some good natured ribbing about his recent comment about someday wanting to be mayor of Chicago while participating in the sixth annual Richard J. Daley Global Cities Forum in Chicago. Daley, 68, who has presided over the nation's third-largest city for 21 years, like his father did before him, announced Tuesday, Sept. 7, 2010, that he will not run for a seventh term. Emanuel said in April during a television interview that "it's no secret" he'd like to run for mayor of Chicago someday. (AP Photo/M. Spencer Green, File)

White House chief of staff Rahm Emanuel, widely expected to leave the White House to make a long coveted run for Chicago mayor, could make an announcement on his decision as soon as Friday, a source close to him said.

Emanuel has not made a final decision, said the person familiar with Emanuel's thinking, who spoke on condition of anonymity for that reason. The dominant factor at this point is the impact the move and the campaign would have on Emanuel's wife and three young children, who live with him in Washington, the source said.

Should Emanuel leave the White House, President Barack Obama is expected to choose an interim chief of staff. That's likely to be Peter Rouse, one of Obama's senior advisers in the White House and his former chief of staff in the Senate.

Emanuel long has expressed interest in running for Chicago mayor; the incumbent, Richard Daley, isn't running again.

Even Obama acknowledges Emanuel would have to leave soon, should he choose to run, to set up his campaign for the mayoral race in 2011.
