well then he should ask for Trump's birth certificate. Then ask for the long form bc. Then news reports and hospital records (from GMS clinic in Moscow, obviously). etc.
He should do exactly what he is supposed to which is to investigate and act as he should.
I get your frustration but at some point we have to stop wanting to get even. The guy who shot the senator wanted that and our nation is slipping in his direction more each day. Yeah we can say that Trump or the Republicans are to blame, but as far as the shooting goes it's always the guy who pulls the trigger who is at fault. Someone has to be the adult in the room and let the law work or we might as well all take up arms against each other as we did a bit over 150 years ago.
Someone might say "the Republicans", well yes the Republicans. They still hate Hillary and Obama beyond all reason, or enough of them do. They'll whine and complain but we can't become like them unless we are pretty good with weapons.
I used to think this hyperbole but there is a possiblilty of an armed insurrection but not for a goal of self determination vs the end of slavery, but a great hatred finding an outlet in death and destruction.
Our current situation is not tenable so we will pull back or advanced towards violence unless something changes. In the meantime I don't want to poke that bear and so I'll wait for people like Mueller to do ther job without taking up that stick either.
