If you didn't get enough Mark Zuckerberg yesterday, you're getting several more hours of him today. 

The Facebook Inc. (FB) - Get Report CEO stands before his second Congressional committee on Wednesday morning, following a largely successful appearance before the Senate Judiciary committee on Tuesday, as shares rose significantly during his remarks. On Wednesday, a similar dynamic occurred, with shares rising about 1.2% near the end of his testimony, compared to down 0.4% before he started.

TheStreet's tech editor Nelson Wang and tech reporter Francesca Fontana are analyzing Zuckerberg's live testimony beginning at 10 a.m., which is viewable here. Please share your questions in the box at the top of the chat window.
