My ancestors escaped to the U.S after escaping violent, state-sponsored anti-Jewish persecution (pogroms) in their village of Antopol.
Stephen Miller, the U.S. political adviser serving as Deputy White House Chief of Staff — and the architect of Trump’s sweeping immigration deportation plan — comes from a Jewish American family whose ancestors immigrated to the United States from Eastern Europe.
Family origins
• Miller was born and raised in a Jewish family in Santa Monica, California. ([Wikipedia][1])
• His maternal ancestors (his mother’s side, the Glosser family) were Ashkenazi Jews who emigrated from the Russian Empire, specifically from Antopol — a town that is now in modern-day Belarus. ([Geneanet][2])
• His great-great-grandfather (Wolf Lieb Glotzer, later known as Louis Glosser) and his wife Bessie came to the U.S. in the early 1900s, escaping anti-Jewish persecution and pogroms in that region. ([Geneanet][2])

In summary:
Ancestral roots: Ashkenazi Jewish ancestors from Antopol, in present-day Belarus, who emigrated to the United States in the early 20th century. ([Geneanet][2])
