will your committee subpoena whitaker to answer additional questions? >> yes. i think the chairman made it clear he expected mr. whitaker to return for a deposition. if he doesn't do that voluntarily, the committee will exercise its authority to require him to appear. before he left our committee room, there were many unanswered questions, contradictions in his testimony, evasive answers the chairman made it clear we have a responsibility to get the truth. the american people deserve that. he is going to be back before the committee for that purpose. >> according to this "new york times" report, whitaker told associates over at the justice department that part of his role was to, quote, jump on a grenade for the president. he told others that the southern district of new york prosecutors needed what he called adult supervision. do you think those comments reflect any direction he might have received from the president? >> it certainly reflects the direction he thought he should take at the leader of the justice department.
