President Donald Trump’s administration asked the Supreme Court in a series of emergency appeals Thursday to allow him to move forward with plans to end birthright citizenship, elevating a fringe legal theory that several lower courts have resoundingly rejected.

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.

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

The Trump administration asked the Supreme Court to stop appeals court rulings that blocked Trump’s order to end birthright citizenship, which would deny U.S. citizenship to children born in the U.S. if their parents are undocumented or on temporary visas.

The Trump administration is asking the Supreme Court to allow restrictions on birthright citizenship to partly take effect while legal fights play out.

Judges in Maryland, Massachusetts and Washington have issued nationwide orders blocking President Donald Trump’s executive order to ban birthright citizenship.
