President Donald Trump has already inundated the country’s immigration system with enough changes to create immediate impacts along the border and across American cities.

President Donald Trump's administration has directed U.S. prosecutors to criminally probe local officials who resist immigration enforcement efforts, intensifying a sweeping crackdown that Trump launched the day he took office.
