I expect the Rats will use their favorite method to stop this: A Federal District Judge in a leftist circuit will issue an injunction.
I'm not so sure that will be necessary.
IMO the pushback is going to come from the agency chiefs regarding what Barr wants access to. Even though Trump has given Barr the power to request what he believes that he needs, I'm not so sure that they are going to comply very easily. That will set up some direct faceoffs between Barr and the chiefs. How far will Barr push it?
And even though Trump has appointed them, it is naive to believe that Wray, Haspel, Coats are "Trump people." We always need to remember that it is a small set of people that the Senate (regardless of which party controls it) will deem 'acceptable' as appointments to these positions.
