Recounting White House aide Stephen Miller’s eastern European roots and his family’s efforts to enter the U.S. through chain migration, Miller’s uncle, David Glosser, slammed his nephew for his devotion to restricting legal immigration.

In a new op-ed in Politico magazine, Glosser claims that if the policies that Miller is advocating for now had been in place when his grandfather immigrated to the U.S. and eventually launched a chain of supermarkets and department stores, Miller likely wouldn’t be a citizen today.

“I have watched with dismay and increasing horror as my nephew, who is an educated man and well aware of his heritage, has become the architect of immigration policies that repudiate the very foundation of our family’s life in this country,” Glosser wrote.

He said his nephew had spent too much time in the “theater of ring wing politics” and has become “numb to the resultant human tragedy and blind to the hypocrisy of their policy decisions.”

Enacting deep cuts to legal immigration, including the method of chain migration that his ancestors used to gain entry to the U.S., has been a staple of Miller’s tenure within the White House. Miller also reportedly is advocating for policy that would make it more difficult for immigrants who entered the U.S. legally to become U.S. citizens or get their green card if they had ever used governmental services like Obamacare or food stamps.
