sources. i'd like to ask you a few questions about it. your investigation found the use of confidential human sources was consistent with existing rules. correct? >> correct. >> the use of confidential human sources here was not solely to gather first amendment protected information? >> correct. and that is the standard currently in the rules. >> and you found no evidence that the decision to use confidential human sources was motivated by political bias. is that correct? >> correct. >> with regard to your policy recommendation, what, if anything, do you believe should be changed and why? >> so as i mention in my opening statement, i think we were surprised to learn and concerned to learn that in an investigation of any political national party political campaign, the confidential human source usage could be approved by only a first-level supervisor. in this insubstance as we note here, some of them were approved at the assistant director level.
