"There are 15 million illegal aliens," Miller said adding that "if each were given a full trial, deportations would take centuries"

White House Deputy Chief of Staff Stephen Miller said in a video that went viral on Friday that undocumented immigrants are not entitled to due process protections when being removed from the United States, arguing that providing full legal proceedings would make deportations unworkable.

"There are 15 million illegal aliens," Miller said. "If each were given a full trial, deportations would take centuries. They had no due process entering the country, and they are not entitled to it when being removed."

Supreme Court precedent has long held that constitutional protections apply to noncitizens within U.S. territory. In Wong Wing v. United States (1896), the Court ruled that the Fifth Amendment's due process clause protects noncitizens from arbitrary detention or punishment.
