Judges can overrule the President’s use of Executive Privilege. Will they? Who knows.
I think the courts will find the claims of EP to be merely thinly veiled attempts to cover up criminal activity.
The problem is enforcing the orders. Historically the power of POTUS is only limited by his own willingness to be limited.
I don’t see this one ever following the law.
We shall see what comes of it, though I suspect it will be little more than some whining and maybe congressional hearings that continue to be obstructed.
At least with the senate (assuming we get a majority) there will be yet another committee for them to obstruct, withhold, and lie to.
