President-elect Donald Trump is expected to name former Goldman Sachs partner and Hollywood financier Steven Mnuchin as his nominee for Treasury secretary, a source said on Tuesday, putting a Wall Street veteran in the top U.S. economic Cabinet post for the first time in eight years.

Mnuchin, who was Trump's presidential campaign finance chairman, could be named as early as Wednesday, said a Republican source close to the decision.

Mnuchin was chosen over several high-profile candidates, including JPMorgan Chase Chairman Jamie Dimon and Republican Rep. Jeb Hensarling, chairman of the powerful House Financial Services Committee.
