Where is the Alfa bank/Trump tower/Spectrum health server investigation?

Among many other unanswered questions, the server communication issue is huge for me. Suspicion of communication between servers, essentially database coordination, part of the social media complicity. Most recent article I’ve seen is here:

Impeachment is a punishment. What are the crimes? When we poll people about support for impeachment, it’s like we’re saying, “Lock her up”. But the question not being asked is - What are we impeaching for? What high crimes and misdemeanors have we identified?

I feel obstruction of justice is just so paltry when it comes to all the crap that Trump May have pulled, from emoluments to the Saudi, UAE, Israel connection, from the server issue I refer to above to all of Kushner’s shady foreign policy; from Flynn’s sanctions discussions (what was the point of a plea deal?) to Roseneft and ? Trump’s commission. What about all these issues? Who is carrying this ball?

I’d like to support impeachment, but for what charges?
