Pay close attention to the people around the Bidens because in a second...
POOF! Out of nowhere appear the girl in WHITE and the girl in PINK...
And POOF! They’re gone again...and it’s a different group again.
And POOF! They’re back again!
And POOF! They’re gone again...never to reappear...
Where did they go? And who are they?
What on earth did we just watch? Is anything real in this satanic world of lies?
