When President Trump ordered a vast overhaul of immigration law enforcement during his first week in office, he stripped away most restrictions on who should be deported, opening the door for roundups and detentions on a scale not seen in nearly a decade.

Up to 8 million people in the country illegally could be considered priorities for deportation, according to calculations by the Los Angeles Times. They were based on interviews with experts who studied the order and two internal documents that signal immigration officials are taking an expansive view of Trump’s directive.
