Here's a brief Wikipedia summary bio for Elizabeth Warren:
Elizabeth Warren (born Elizabeth Herring; June 22, 1949) is an American attorney, law professor, and United States Senate candidate. She served as Assistant to the President and Special Advisor to the Secretary of the Treasury for the Consumer Financial Protection Bureau. She is also the Leo Gottlieb Professor of Law at Harvard Law School, where she has taught contract law, bankruptcy, and commercial law. In the wake of the 2008-2011 financial crisis, she became the chair of the Congressional Oversight Panel created to oversee the U.S. banking bailout (formally known as the Troubled Assets Relief Program). She long advocated for the creation of a new Consumer Financial Protection Bureau, which was established by the Dodd-Frank Wall Street Reform and Consumer Protection Act signed into law by President Barack Obama on July 21, 2010. As the special advisor she worked on implementation of the CFPB.
On May 24, 2010, Time magazine called Warren, Federal Deposit Insurance Corporation Chairman Sheila Bair, and Securities and Exchange Commission Chairman Mary Schapiro the "New Sheriffs of Wall Street" in a cover story. On September 17, 2010, she was named a special adviser by President Obama to oversee the development of the new Consumer Financial Protection Bureau. The position included the responsibility of recommending a director for this new entity. She was not chosen for the post, with Obama instead nominating Richard Cordray, subject to Congressional approval.
