Yellen, President Obama's nominee to lead the U.S. Federal Reserve, is sworn in to testify at her U.S. Senate Banking Committee confirmation hearing in WashingtonWASHINGTON (Reuters) – The Senate Banking Committee on Thursday licensed Janet Yellen's nomination to transform the primary lady to guide the Federal Reserve, sending it to the entire Senate for a closing vote. If established, as is extensively anticipated, the current number two at the primary financial institution will replace its chairman, Ben Bernanke, when his term expires on January 31, making her probably the most powerful woman in world finance. The vote was once 14 in favor and eight against. (Reporting Via Alister Bull and Margaret Chadbourn)
