Live: Janet Yellen speaks to Congress

Fed Chair Janet Yellen went in front of the Senate Banking Committee Tuesday. One of the highlights so far has been a tweet from Bill Gross at Janus Capital, who said the central bank chief is speaking from "a 50-year-old textbook." She also has expressed concerns over Brexit and noted that the benefits of the recovery have been uneven.

In response to a question about presumptive Republican presidential nominee Donald Trump's proposal that he could renegotiate U.S. debt with foreign creditors, Yellen said the damage from that could be "very substantial."
