Question for those familiar with political law: why do these powers even exist? Why is it possible for one person to unilaterally dismiss or pardon criminal charges at all?
Note that I am not arguing whether or not this instance is justified or corrupt/BS, just explaining that each administration can direct what cases they want to enforce. You can’t prosecute everything, and there is political judgment involved as to what is a priority.
The DOJ usually operates with some level of autonomy. Trump has no interest in that.
