Cut through all the speculation and it boils down to one real thing. Either the NRA, through some of the people in it, broke some law(s), or they didn't.
IF there is proof that someone in the NRA has been breaking the law, in our name, then they should be identified and punished.
An accusation is not proof. An investigation is not proof. The findings of an investigation might be.
IF it comes to an actual investigation, if the NRA doesn't have every scrap of paper or electronic file about anything they are asked for, if they don't have it instantly available to turn over, they will be accused in the press of "stonewalling" or at the least being uncooperative.
We need to look at actual facts, and the law, and not just listen to the mob brandishing torches and pitchforks, chanting "burn the witch!!"
Personally, I find the idea of "Russia influencing the election through the NRA..." to be ludicrous. Does anyone actually think it was because Russian paid them that the NRA endorsed Trump over Clinton???
I'd think it was more like "thanks for the check for doing what I was going to do anyway..."
If some rules about how much can be given to whom, from where, (etc.) were broken, then the people who failed to do their "due diligence" need to pay for their failure. Aside from that, what is the issue??
