I believe Congress might have the last say. Which is it. The evidence was not strong enough or Barr is just not going to charge the guy that gave him the job. You are all over the place.I think a group of lawyers will say anything you want them to say if you pay them enough.
Barr has the last say on obstruction and conspiracy charges. That say is based on Muellers findings and evidence.
The evidence was not strong enough to support charges.
End of story.
