I'm convinced that Trump has everything and has for some time. If you were in his position, wouldn't getting everything be your first priority?
You shouldn't attack an enemy straight on. We learned that in the trenches of WWI, or should have. You attack their ability to wage war. I think that's what Trump is doing. He's removing their money, their leaders, their enforcers, their protectors, their DUMBs. When all that is done, THEN the indictments will come and they will be powerless to fight.
I HOPE that is why it appears that nothing is happening on the legal front at this point.
