I just hope that the Justice Department goes back to being independent, and not a tool of the administration. That is very much the norm, and it was one of the biggest red flags of the current administration. US DOJ should be making these calls independently. It should not be up to the administration to decide.
Certainly, Biden can make his AG choice in part based on their thoughts about the general approach, but he should not be getting anywhere near the decisions involving that case. Both because of the need for independence of the agency, and also because it involves his son.
