GOP-led Senate Intel Committee subpoenas Don Jr. over Russia

I’m a dotard so here’s my crazy old fart theory:
One asks oneself why the Senate Republicans care about calling in Jr. Mint specially after McConnell says it’s all over.
My take is that these geniuses want to incite, as it were, a lawsuit to quash the subpoena, taking it all the way up to SCOTUS who will quash it if lower courts haven’t thereby (they think or at least hope) that there would be a legal basis for the White House to block all subpoenas into all things Trump.
Of course, like all things Trump, there are flaws. While making the infantile POTUS happy, quashing these subpoenas on bullshit grounds, even with the current SCOTUS panel, isn’t a done deal. So this may have the opposite effect: A declaration that Crooked Donnie’s claim of executive privilege is legally bullshit. And since the House isn’t exactly rushing to action, this may actually speed things up.
Too, one of Donnie’s very few replacement tailwinds for 2020 having lost all the tailwinds from 2016 is POTUS under attack. If the process in the House moves faster, specially because of this tactic in the Senate, by the election, it won’t be POTUS under attacked but POTUS attacked and so fully documented as unfit for office that even the Trump-enabling corporate media won’t be able to downplay it. (Of course, being great goose steppers – lemmings for those afraid of Godwin’s law – they don’t need extra motivation they’re always so motivated.)
