World Bank President Robert Zoellick speaks at an opening news conference of the spring International Monetary Fund (IMF)-World Bank meetings in Washington, in this April 19, 2012 file photo. Economists, investors and veterans of past administrations are appraising potential successors to Treasury Secretary Timothy Geithner. Zoellick, whose term as World Bank president expires in June, might prefer running U.S. diplomacy to overseeing the nation's troubled finances.
