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.

Washington — President Trump invoked muscular presidential powers to begin a sweeping crackdown on immigration following his inauguration on Monday, tasking the military with border enforcement, moving to designate cartels and gangs as terrorist groups, shutting down asylum and refugee admissions and attempting to terminate birthright citizenship.

Four immigration court officials were removed from their positions on Monday. It’s unclear who is in charge at this point.
