Elizabeth Warren (born 1949) is an American academic and politician, and the current senior U.S. Senator from Massachusetts and a Democrat. She is the Leo Gottlieb Professor of Law at Harvard Law School -- where she taught contract law, bankruptcy, and commercial law -- and devoted much of the past three decades to studying the economics of middle class families. In the wake of the 2008-9 financial crisis, she became the chair of the Congressional Oversight Panel created to investigate the U.S. banking bailout (formally known as the Troubled Assets Relief Program). In that role, she has provided a critical check on the U.S. Department of the Treasury and has been a leading advocate for accountability and transparency. Since 2007, she had advocated for the creation of a new Consumer Financial Protection Agency, which was established by the Dodd–Frank Wall Street Reform and Consumer Protection Act signed into law by President Obama in July 2010.
