Via Tengrain, I heard the news that Donald Trump Jr has been subpoenaed by the Senate Intelligence Community. Seeing as the GOP holds power in the Senate, I am suspicious of this maneuver... Chairman Burr doesn't seem to be the sort of guy to break ranks with his party. I have a feeling that the Senate Intel Committee will lob softball questions at dopey Donnie (funny that pop culture portrays Eric as the stupider of the two) so he can cobble together a narrative that he can fall back on in case testimony before a hostile House takes place. Steve Bannon infamously opined that Bob Mueller could crack Don Jr like an egg, and I imagine that Adam Schiff could do the same.
I can't imagine Donald Sr taking this lying down, but I haven't seen any indications that he has turned on Burr or the rest of the Republican Senate. This leads me to believe that he knows it's a softball lazily lobbed so his son can hit it, rather than a shot across the bow. I'd like to believe that Burr is genuinely perturbed by the dictatorial turn which the PotUS has taken, but I just don't trust him or anyone in his party.
