Janet Yellen, considered as one of the world's top economists, was on Tuesday sworn in as the first female Treasury Secretary of the United States.
Yellen, 74, was administered the oath of office by Vice President Kamala Harris.
Former chair of the Federal Reserve, Yellen was confirmed by the Senate by 84-15 votes on Monday.
