I'm sure Jack could put in a good word for Mark in Georgia, if he coughs up enough republican congress people, after Jack is done with Donald or has him well on the way to a cell. Jack could probably shave many years off Mark's Georgia sentence, if he were to testify on TV in Georgia against Trump, I imagine it would also help to shave years off his sentence. Trump and the magats will go nuts if Mark flips on Trump and people in congress should worry too, Mark knows where all the bodies are buried. The TV trial in Georgia will have the biggest political impact IMO and Donald might be already in federal custody when his trial begins in Georgia. Also, the rules for witness tampering and intimidation during pretrial in Georgia are very strict and result in jail until trial.
