yes Trump set the stage, negotiated with Terrorists while blocking out the rightful gov't just as he was walking out the door and then said 'now its on you Biden. good luck'.
We all understand if you are taking over a house and as the person leaving walks out lights it on fire, it is your fault as the new home owner, as to how much damage you can stop happening.
But ignoring the arsonist who set it on fire as he left is foolish. Biden IS responsible for the elements he could control. Trump WAS responsible for the things he locked in to motion that were all disastrous.
