WASHINGTON, Feb. 13 (Xinhua)-- Steven Mnuchin, a former banker, was confirmed on Monday by U.S. Senate as Treasury Secretary.

Mnuchin won in a 53-47 Senate vote in which only one Democrat, Senator Joe Manchin of West Virginia, voted in favor, and the rest supports are all from Republicans.

The confirmation is expected to help President Donald Trump's administration to push ahead with its goals to dismantle financial regulations and slash taxes.

Mnuchin, 54, was Trump's top fund-raiser during the presidential campaign.

The U.S. Senate Finance Committee once postponed votes on him out of concerns that the treasury secretary pick may give false testimony on foreclosure practice by OneWest Bank, of which Mnuchin was former chairman.
