The American Civil Liberties Union (ACLU) sued Wednesday over President Trump’s expansion of a program that allows immigration officials to carry out swift deportations. Trump’s Department of Homeland Security on Tuesday issued a rule enabling expedited removals to take place nationwide for migrants who cannot prove they have been in the country for two years.

Put simply, under Trump’s order, the children of most undocumented immigrants wouldn’t be US citizens, nor would the children of people in the country on student, work, or tourist visas. This is more than a reinterpretation of the 14th Amendment — it’s an attempt to do away with the jus soli principle that undergirds US citizenship.

The American Civil Liberties Union on Monday night filed a lawsuit challenging President Donald Trump's controversial executive order that seeks to end birthright citizenship.
