Who are complicit in this entire money laundering/obstruction of justice fiasco with Trump, his cabinet, and all the rest of the GOP, prior to the Senate impeachment trial?

Otherwise, it seems to allow them to cast judgment on the guilt or innocence of Trump when they are complicit in the same crime. That would be a major miscarriage of justice, a blight on our democracy, an affront on justice and the rule of law. To me, an impeachment that ends in Trump's acquittal based on the votes of co-conspirators in the crimes he is accused of cannot be allowed to advance. Surely the Dems in power see the same thing and feel the same way.

I can imagine a scenario where one Congressperson is brought to justice by his or her colleagues, but what if the cancer is so pervasive that it would ensnare a dozen or dozens of them? Could such a sweep be successfully tackled by the Dems, and prior to the Senate hearing at that?

Not asking this as a Democrat. Asking this as an American.
