Perhaps Stauber is more concerned with being on Trump's good graces, than he is with the economy of his constituents. A move is timely if he pressures the mentally declining man and his economic advisor pool, before it is too late. With Vance seeming disinclined to exercise 25th Amendment duties, Stauber may either see what a stonewall looks like, or he moves the needle.
Either way, he has to try. And that involves contact and discussion with JD.
Emmer cannot avoid having a role.
