He was involved in what was a multi-agency response. It was office of the vice president. It was the office of the president ... in every obstruction case, in every perjury case, the key issue is motive and the underlying offense. Even though the underlying offense is not charged, in every perjury case the real question is did the person have a reason to lie. So the underlying offense is always in play."
