There is a term used that I believe applies: “reckless disregard for the truth”. Brennan didn’t care what the truth is. That is a common trait in both politicians and the CIA.
Well he didn’t want the truth to come out because he knows it exposes him and Obama. So I wouldn’t say he didn’t care, rather he cared to keep the truth hidden. Hoping to mask it in a bunch of lies so that in the end it will be a he said/she said in the voters mind. They get their antifa supporters to riot and the GOP gets scared and quits looking at it.
