According to Steve Bannon, who has skin in the game and is facing 4 months in prison for Contempt of Congress (for the Bannon haters about to reply) Boris Epshteyn, made mention to SB that the VP pick has been known in the Trump Camp for some time (6-12 months) and is NOT someone that has been on the radar... to date. YMMV
I believe that the candidate in question will have extreme MAGA DNA and be beyond reproach.
I should have pinged everyone in my original post...
