It might be deal time for Mark, but only if he can deliver Republican congressional heads, they don't need him to put Donald away for good, so not much of a deal to be had there. However, Mark controlled access to Trump and knows about all the pardon requests from congress, we only know about a half dozen, so far. Mark was the hub of a hub and spoke conspiracy and several plots, some involving congress people, Mark was also Donald's cock and brain for much of the fiasco. If anybody is gonna get a deal it will be Mark, he just doesn't have enough incentive to do so, yet and I'm sure his lawyer is working on one if Mark's got a fucking brain. If he rat's out enough congress people to Jack, he might just earn himself a get out of jail free card, or a reduced sentence and limited charges.
If Jack could nail Gym Jordan and a few others I'm sure it would make his day. The job is not done until he goes through congress over the J6 conspiracy, and he would be doing that this year and next if Mark and a few others crack. Arrogance, stupidity and hubris lead them to this point of a provable conspiracy with receipts, witnesses and no shortage of rats.
