christopher steele as a source in 2016 because of reliability and credibility, because he was going out and talking to media organizations, that's significant. when the fbi looks at sources every once in a while we've got to validate that they and the opinion of the case agent are being truthful. and so, they closed him because they felt they had credibility issues. so, that's a problem if they then turned around and used this information in a fisa search application or fisa wire tap application and never volunteered anything to the judge, but there's another aspect of that. i worked hundreds of counter intelligence cases over 30 years, this is very important. it's totally abnormal and unusual, they would then turn around and have the source briefed and debriefed by an official of the department of justice. those people are supposed to make sure there are balance in these kinds of things.
