After months of avoiding details about a divisive plan to end birthright citizenship, President Donald Trump’s administration is rolling out a series of new documents that offer a stark glimpse into how it would implement an executive order that upends the century-old understanding about the benefits of being born in the United States.

BOSTON (AP) — A federal judge on Friday blocked the Trump administration from ending birthright citizenship for the children of parents who are in the U.S. illegally, issuing the third court ruling blocking the birthright order nationwide since a key Supreme Court decision in June.

The ruling from the U.S. Court of Appeals for the Ninth Circuit brings the White House’s theory of citizenship closer to a full Supreme Court review.
