U.S. President-elect Donald Trump will likely ask a senior Goldman Sachs banker to coordinate economic policy across his administration, turning again to Wall Street for expertise in managing the world's largest economy, a transition official said on Friday.

Trump's pick of Goldman President Gary Cohn, 56, to head the White House National Economic Council comes despite Trump's past criticism of the financial sector's power.

Trump hammered Goldman and its CEO Lloyd Blankfein during the presidential campaign, releasing a television ad that called Blankfein part of a "global power structure" that had robbed America's working class.
