If Barr believed it, Bash would still have a job.
Do you know for a fact that Bash was fired, or just assuming he was? If he didn't agree with his report, why did he allow a B$ investigative report to be released? You act as if he had to allow a report be published that he believed to be a lie. Did you also notice that he said he would not be releasing and documents, just because Trump said he had unsealed them?
