Obama Chief-of-Staff Bill Daley Resigns Effective End of January

WASHINGTON (The Blaze/AP) -- William Daley is resigning as President Barack Obama's chief of staff just one year into the one of the most pivotal jobs in politics, senior administration officials said Monday.

Daley's job as day-to-day manager of the White House operation had already been changing - if not diminishing - as senior Obama aide Pete Rouse took over more of those duties in November. At the time, the Wall Street Journal reported Daley's responsibilities had been cut back, and Business Insider said he was, in effect, "demoted."

Yet Daley was not expected to leave the job and return to Chicago, where his family has long held a political dynasty, until after the November presidential election.

Officials confirmed the news on condition of anonymity because the president had not yet announced it. The president planned to do so later Monday afternoon.

Obama will now have the third chief of his staff of his presidency in the midst of a re-election year.

Daley is to be replaced by Jacob Lew, now the White House budget director. The change will be effective at the end of the month.

Obama chose Daley to be his White House chief of staff in January 2011, but the former banker and veteran political fighter Daley has had a somewhat rocky tenure.

In the least, the job has not seemed like the best fit.

Daley had been brought in to improve relations with the business community, Republican lawmakers and others with whom he had built ties over the years. He replaced Rahm Emanuel, who is now Chicago's mayor.

Daley served as commerce secretary under President Bill Clinton and ran Al Gore's 2000 presidential campaign. He's the brother of recently retired Chicago Mayor Richard M. Daley and the youngest son of legendary Chicago Mayor Richard J. Daley.

Daley's resignation was first reported by the Chicago Tribune/Los Angeles Times.
