Daniel Roque Olivares was driving to work on U.S. Highway 81 in Oklahoma when a state trooper pulled him over and detained him for violating federal immigration laws. The stop is part of a broader crackdown enabled by deputizing Oklahoma Highway Patrol officers as immigration agents, a program pushed by Lance Schroyer, Trump's nominee to lead ICE. Oklahoma's enforcement has been described as harsher on undocumented immigrants than almost any other state.
