Someone posted this on Reddit likening the Weisselberg subpoena to DoJ following the script on how to roll up a criminal organization like the maffia:
1. Get a low level person to flip (Papadopolopolous, Page, whoever). **CHECK**
2. Keep flipping people upwards till you get the consigliere (Cohen). **CHECK**
3. Have the consigliere flip on the money man (Weisselberg). **CHECK**
4. Flip the money man, because he has paper proof on everything else. **YOU ARE HERE**
5. Roll up the rest of the organization (TrumpCo, GOP) with the evidence from those two.
