Janet Yellen: Objective is a 'robust recovery' for US economy

Janet Yellen, the woman the White House wants to run the Federal Reserve, has defended its stimulus efforts and vowed to continue them if confirmed.

In her first appearance in front of Congress, she said her objective was "to ensure a strong and robust recovery so that we get back to full employment".

Ms Yellen has been chosen to lead the US central bank once Ben Bernanke's term ends in January. To be confirmed, she needs 60 votes.
