All these clowns can seem to do with power is abuse it, forget the country. Good luck trying to get inside the DOJ, it's the executive branch remember, and Joe or Garland is not gonna compromise anything for these assholes. Republican congress people won't recuse themselves, neither do republican SCOTUS justices, they don't comply with subpoenas either, so good luck getting any enforced, unless they want to embarrass and entrap the republicans.
I think it's more about trying to get away with their crimes at this point than scoring political points. Trump will want a Hunter investigation that won't end well for them IMHO. If they try to obstruct justice, they may find themselves on the wrong side of it in court. J6 could not have happed without inside congressional help and coup planning, the storming of the capitol was to give the treasonous republican congress people time to delay the certification and bring in the fake electors. It was all part of a bigger plan, taking the capitol would have been meaningless without help from inside congress to fraudulently fuck with the electoral vote count act using delay and fake electors to throw the results into confusion. For many of them J6 went horribly wrong, but 140 of them voted to delay the certification after the capitol was invaded and stuck with the illegal "plan" to make Trump king and thwart the will of the voters.
