volume two for reasons you explained special counsel did not make a determination whether there was an obstruction of justice crime committed by the president. is that fair? >> yes, sir. >> in explaining what special counsel didn't make a decision, the report on the bottom of page 2 of volume 2 reads as follows. the evidence we obtained about the president's actions and intent presents difficult issues that prevent us from conclusively determining that no criminal conduct occurred. while this report does not conclude that the president committed a crime, it also does not exonerate him. now, i read that correctly? >> yes. >> now, your report and today you said that all times the special counsel team operated under was guided by and followed justice department policies and principles. so which doj policy or principle sets forth a legal standard that an investigated person is not exonerated if their innocence from criminal conduct is not conclusively determined?
