The most insightful line is the last sentence of his bit where he ties in the “pre-existing narrative” of the Tea Party with low taxes...madmen..you do the math George..
Notice Jon DIDN’T condemn trying to associate the Tea Party with terrorists... he even kind of reinforced it, with the “with low taxes...madmen..you do the math” line.
Brian showed his bias and Jon’s doing damage control.
He conceals the real issue (Brian Ross trying to falsely associate the Tea Party with terrorists) by reprimanding Brian for failing to fact check and falsely accusing an innocent guy of mass murder.
People who hear it come away with the idea that Brian Ross was lazy in his reporting, as opposed to the idea that Brian Ross was intentionally trying to demonize the Tea Party.
