No. Nothing will happen, the same way that nothing will happen when trump and his administration are investigated for their wrong doings. There's a couple of reasons for that.
There's always a fall guy.
It's always legal. Shaddy, immoral, unethical etc. Sure. It's still done legally regardless of the perpetrators.
Precedent. If you open the can of worms expect a full retaliation. If one side goes after the other the next administration, or current, can expect the same. Guess what. They'll probably get caught too, so they won't go after anyone.
It's all political grand standing to make us hate each other, without an end to the corruption and greed.
