President Donald Trump has begun to radically change how the U.S. government handles immigration, from challenging long-held legal concepts about who gets citizenship to using the military to transport migrants back to their countries of origin.
Trump’s administration is doing more than reshaping the approach of the federal government toward migrants: It has now ordered state and local officials to comply with all federal immigration laws, including any new executive orders. It has warned that if those officials refuse, it may criminally prosecute them.
