Gym's personal concerns and exposure over J6 is the main motivator for him and others here, it is an act of desperation. Mark Meadows and other Republicans who want a deal from Jack will sell his ass for time off a long prison sentence. He wanted a pardon for something, and Jack will go where the evidence leads and the rats point.
I also think that next time around Gym and others involved in J6 will face challenges over the 14th to keep them off the ballot, once the ice is broken with Trump and more comes out during the trials. The whole thing was done in Georgia and other states so that the insiders in congress could pull it off with fake electors, they voted to delay even after the capitol was attacked, it was an inside job too. J6 could not have happened without inside congressional help and collusion. They had messages and phone calls that day and meetings in the WH to plan it and those they met with are in a great deal of trouble in Georgia and with Jack, most will want a deal and assholes in congress would be worth one. Gym should be worried because Jack may come calling one day, once he has Trump's scalp on his belt, Jack will grow bigger and scarier over time and convictions.
