There's an entire Congress up there, of which Trey Gowdy is a very visible part. But he's not the only one and I don't think it's fair to lay the blame on him alone. That said, I think Mr. Gowdy's work during the Obama years laid the groundwork for what is happening today with the IG report that is coming up, and today's House memo.
Especially knowing what we now know about how incredibly corrupt the Obama machine was from top to bottom, not to mention the spaghetti-spined NeverTrumpers, I'm not surprised Gowdy was not as successful as we would have liked. It was a stacked deck.
