The Trump administration is pushing for the the U.S. Supreme Court to allow some restrictions on birthright citizenship even as legal battles continue over President Donald Trump’s orders to end what has long been seen as a constitutional promise.

Acting solicitor general Sarah Harris filed a request to restrict orders blocking Trump’s executive order on birthright citizenship restrictions signed earlier.

Donald Trump took the fight over his attempt to restrict automatic U.S. birthright citizenship to the Supreme Court on Thursday as the Republican president's administration asked the justices to narrow a judicial block imposed on this key element of his hardline approach toward immigration.
