A federal judge has again blocked President Trump's order to end birthright citizenship, meaning the citizenship status for babies of undocumented immigrant parents is protected for now.

A US District judge from New Hampshire today granted class action status to a lawsuit challenging the order brought on behalf of a pregnant immigrant to immigrant parents and their infants by the ACLU.

But the ruling applies to immigrant children nationwide.

Now, New Jersey Attorney General Matt Plantkin led the initial multi-state effort defending birthright citizenship.

And the ruling comes just after the US Supreme Court declined to rule on the merits of that case and instead limited the ability of federal judges to issue nationwide injunctions against the president's policies while also though leaving the door open for challengers to bring class action lawsuits.

The judge's order includes a 7-day stay.

That's to allow the Trump administration to appeal.
