WASHINGTON – President Donald Trump’s attempt to sharply limit who is automatically an American could affect the legal status of as many as 255,000 babies born in the United States each year, according to some estimates.

In addition, the parents of millions more would have to prove the citizenship status of their newborns.

Those are some of the major consequences at stake when the Supreme Court debates on April 1 the legality of Trump’s order.

Here’s who could be impacted if the court, which has a 6-3 conservative majority, sides with Trump.

The 14th Amendment grants automatic citizenship to “all persons born or naturalized in the United States, and subject to the jurisdiction thereof.”
