He's their boy
The part sickens me about the atrocities at our border with Mexico, engineered by Stephen Miller, is Miller doesn't operate in a vacuum. And Miller goes to all these parties, where, out of the public eye, away from revealing cameras, the wealthy and powerful gather around him, slap him on the back and shake his hand, saying, "Good work, Stevie-boy--keep it up. We're with you all the way!"
