Jan 11 (Reuters) - Timothy Geithner, who played a lead role combating the global financial crisis as U.S. Treasury secretary, will step down from his post on January 25.
President Barack Obama on Thursday nominated White House chief of staff Jack Lew to succeed him.
If Lew is not confirmed by the Senate by the time Geithner departs, Deputy Treasury Secretary Neal Wolin will serve as acting secretary, a Treasury official said.
