TBH in actual Government Employee Lingo, the verbiage is
Fuck up, Move up!
Two things here.I believe that POTUS intention, besides embarrassing this Libtard from Taxatwoshits is to draw attention to the DNA sights, and their nefarious work, however deep it goes.
Second; If Lizzy Borden Warren's Mom was part Cherokee, [significant enough for people to notice] then her Grandma would be at least a half breed, her Mom would be 1/4 and Lizzy would by simple mathematics 1/8th Cherokee. She would have a lot more distinguishing features than her "High Cheekbones" and last I checked there's a big difference between 1/8th and 1/1024 or even 1/64th for that matter. So many more generations than her Memau! IJS
But this is all trivial as it's part of the movie. It's the DNA sights,[23 and Me] and such that's important here. What exactly is it their doing, enough to get POTUSto call them out this much ?
