Report: Trump has chosen his nominee for secretary of treasury

President-elect Donald Trump has reportedly picked Steven Mnuchin as his nominee for the secretary of treasury position, and a top Trump aide told NBC News Tuesday evening that he could make the official announcement as early as Wednesday.

Mnuchin was Trump's presidential campaign finance chairman, and also has long running ties to Wall Street. He spent 17 years at Goldman Sachs, and also worked at Soros Fund Management. Mnuchin served as chairman of Dune Capital Management and co-founded OneWest Bank Group.

After running a populist campaign that targeted Wall Street and even Mnuchin's previous employer, Goldman Sachs, the move is one that could baffle some Trump supporters.

As secretary of treasury, Mnuchin would serve as chief financial officer of the government, recommending tax policies, overseeing economic policies, and handling sanctions of other countries. The secretary of treasury also manages the public debt.

Mnuchin made headlines earlier this month when it was announced that the bank he co-founded, OneWest, had been accused of discriminating against minorities during his time as chairman.

He has no previous government experience, and if appointed, would be the third secretary of treasury who has previously worked at Goldman Sachs.
