What to expect in James Comey's upcoming testimony

Benjamin Wittes, a friend of fired FBI Director James Comey, spoke to Yahoo News and Finance Anchor Bianna Golodryga and Yahoo News Deputy Editor Dan Klaidman about the fallout from Comey's dismissal and his scheduled testimony. Wittes, editor in chief of the Lawfare blog, said, "I would fully expect him to walk in the door having thought very carefully about ... what the maximum amount he could say is and wanting to be as forthcoming as he possibly can be, given the gravity of the situation at hand."
