I hadn’t thought of that, very interesting and/or likely.
The witness list is out.

well worth reading. 5 pages
1. Devon Archer
2. Hunter Biden
3. Alexandra Chalupa
4. David Hale
5. Tim Morrison
6. Nellie Ohr
7. Kurt Volker
8. anonymous whistleblower
9. all individuals relied upon by anonymous whistleblower in drafting secondhand complaint.
IMO, 8 & 9 are where most of the fireworks will be. Perhaps Ciarmarella is the WB, but I’m inclined to think it’s someone else and C is just the patsy.
