Mate sadly the US had 4 years of open borders, whilst Trumpster may lessen the damage its kinda too late, no one, no one, can fix this sort of damage. I am not blaming Sloe Biden, everyone, everyone, KNOWS that Sloe did not even know what state he was in, let alone the ability to make any sort of serious decision, but I would think its unlikely that anyone will find out who was making the decisions. I am kinda on the Obama Bin Liner angle, but well its all academic now.
