White House officials said Friday that President Bush is "moving forward" in the search for an economist to replace Federal Reserve Chairman Alan Greenspan.
Mr. Greenspan heads the U.S. central bank and is scheduled to retire in less than four months.
He has been helping the Federal Reserve guide the world's largest economy since 1987.
News reports say Mr. Bush is probably considering several candidates, including Glenn Hubbard, a past economic advisor to the president, Harvard economist Martin Feldstein, or Ben Bernake, chairman of the council of economic advisors.
