There's a spicy debate underway in Washington, D.C., about who actually calls the shots at the Department of Homeland Security. On paper, DHS is led by a Senate‑confirmed secretary. But in private corridors of power, one name keeps coming up as the real force shaping US immigration strategy: Stephen Miller, the hardline adviser whose fingerprints are all over the country's most controversial immigration initiatives.
The issue exploded into the open when Democratic Senator Andy Kim of New Jersey took the unusual step of publicly questioning whether the department's official leaders were really in charge. In blunt terms, Kim warned that Miller, an unelected White House policy aide, was effectively running the show at DHS — especially on immigration.
