An appeals court will not allow the Trump administration to end birthright citizenship for certain children of immigrants, in a ruling that could propel the issue to the Supreme Court.

A U.S. appeals court on Wednesday let stand an order blocking President Donald Trump from curtailing automatic birthright citizenship nationwide as part of the Republican's hardline crackdown on immigration and illegal border crossings.

The 9th Circuit Court of Appeals declined Trump's request to suspend an injunction blocking his executive order to ban birthright citizenship.
