The only way President Biden would do something like this is if he has no plans on seeking re-election. Even then, I seriously doubt he would do this. He would face a firestorm of criticism within his own party and even outside his party.Biden is going to pardon Trump. I think this is the plan the left is making to win the 2024 election.... Or neutralize Trump.
President Biden just needs to sit back, continue what he is doing, and let the legal process in all of Trump's investigations play out. There is no need for him to involve himself in any of this.
