I’ve assumed the story is false. But remember, the story was being used not to attack Newt, but to attack Brit — when people were upset that he wasn’t kissing up to Newt, this story came out to “explain” why Brit hated Newt, and therefore couldn’t be trusted to tell us the truth about Newt.
So, what we are SUPPOSED to believe I guess is that the story is patently false, and ALSO that Brit for some reason believed the story is true, and therefore hated Newt.
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.
So what if the story was outed it should have been. This is a big deal, a journalist and married congressman having a gay affair? This was obviously a very troubled individual and it is doubtful that this one event was the primary cause of his decision to take his own life.
You believe the word of an aggreived father (Brit Hume) who set the record straight upon his retirement from a highly public position.
Neither Newt Gingrich, nor republicans in Washington, killed Brit Hume's son however much the rumor might serve people like Pelosi.
