Sen. David Vitter (R., La.) speaks to TheStreet's Joe Deaux in an exclusive interview following Federal Reserve Chairwoman Janet Yellen's first testimony to the Senate Banking Committee. Vitter says he thinks the Fed's historically low interest rates have only served to offer markets a 'sugar high' and that a day of reckoning rests ahead. Vitter says Yellen won't be aggressive enough on too big to fail banks. The senator also says he hopes Yellen is more vocal about income inequality.
