President Barack Obama, newly re-elected, now confronts two questions that he has been avoiding for more than a year: Who will replace Treasury Secretary Tim Geithner and when.

Obama's decision, probably among the first personnel moves he makes, may set in motion a revamping of his economic and national security team, according to four current and two former administration officials who spoke before the outcome of the election was clear. Some advisers will depart and others will take on jobs that are opened up.

"The first thing is Treasury," said former White House Chief of Staff Bill Daley. "You kind of have to figure out that one before everything else."
