What possible motive would there be for someone close to Newt to try to concoct a suspicion by anyone that Newt was involved in Hume's suicide? It could only harm Newt, and badly. Your theory makes no sense.
I’m talking about here at FR. The first place I read this story was in a thread where pro-Newt folks referenced it to explain why Brit was being so hard on Newt. Then they said it should have forced Fox to remove Brit from the debate because he couldn’t be fair.
I have no idea who actually generated the story — I’m only talking about how I heard about it here from pro-Newt folks attacking Brit.
